AMD Ryzen 7 7800X3D Overclocked to 5403 MHz With ROG Crosshair X670E Hero | SkatterBencher #60

hello and welcome back in today's video I'm overclocking the AMD ryzen 7 7800 x30 processor all the way up to 5.4 gigahertz using the Asus Rog Crosshair x670e hero motherboard and EK Quantum custom Loop water cooling in an ironic Twist of events I found that the successor to the locked 5800 x3d is the most tunable x3d processor yet and I genuinely enjoyed exploring the various overclocking strategies to squeeze more performance out of this 7800 X3 processor I hope you equally enjoy the video that I've prepared for you alright we have a lot to cover too so let's get started the AMD ryzen 7 7800 x3d is the direct successor of amd's very first x2d CPU the ryzen 7 5800 X 3D it is also part of the third wave of AMD ryzen 7000 am5 processors the first wave of Zen 4 ryzen 7000 processors launched on August 29 2022 and consisted of four x skus ranging from the 6 core Horizon 5 7600x to the 16 core ryzen 9 7950x the second wave of horizon 7000 processors launched on January 4 2023 it consisted of three non-x skus ranging from the 6 core ryzen 5 7600 to the 12 core ryzen 9 7 900. the third wave of Verizon 7000 processors also announced on January 4 but only available since February 28 consists of exclusively x3d variants with the 3D V cache the lineup consists of three skus ranging from the 8 core ryzen 7 7800 X 3D to the 16 core ryzen 9 7950 x3d we already overclocked the right 2009 7950 X3 and scatterbrancher number 56 the ryzen 9 7900 x3d and scatterbanger number 58 and the 5800x3d and scatterbanger number 39. I won't say too much about the technical aspect of 3D V cache as plenty of other media will cover that part of the x3d story long story short AMD has a 3D stacked additional L3 cache on top of the CCD to expand the ondi cache capacity that in theory should help improve the performance in latency sensitive workloads the ryzen 7 7800x3d has a 1 8 core CCD and 16 threads the base frequency is 4.2 gigahertz and the maximum listed boost frequency is 5 gigahertz the TDP is 120 Watt and the PPT is 162 Watt in this video we will cover 5 overclocking strategies first we rely on AMD PBO and Expo performance boost Technologies second we use the Asus x3d OC profile available in the Bios third we tune Precision boost overdrive with curve optimizer fourth we rely on asynchronous e-clock mode lastly we pursue a manual overclock however before we jump into the overclocking let's first have a look at the hardware and the benchmarks that we'll be using in this guide the system we're overclocking today consists of the following Hardware the amalab's easy fan controller is the base version of the efcsb that I already covered on my channel I also have already covered how I used the Elmo Labs easy fan controller in my overclocking guides to make a long story very short I connect the EFC to the evc2 device to monitor the ambient temperature water temperature and fan duty cycle I also include these results in my Prime 95 stability tests I also use the almolabs ESC to map the radiator fan curve to the water temperature without going into too many details I've attached an external temperature sensor from the water in the loop to the EFC then I use the low high setting to map the fan curve from 25 to 40 degrees of water temperature I use this configuration for all overclocking strategies the main takeaway from this configuration is that it gives a good indicator of whether the cooling solution is saturated we use Windows 11 in the following Benchmark applications to measure performance and ensure system stability before we start overclocking of course we have to check the performance at stock settings please note that the Precision boost 2 boosting algorithm governs or manages the performance over base specification the standard parameters of the Precision boost algorithm for the ryzen 7800 x3d are as follows we used the xiaomino Boost curve and Super PI 32m to check the CPU boost behavior and per core maximum effective clock frequency the Boost frequency when one thread is active is about 4758 megahertz and trails off to 4486 megahertz when all cores are active we also find that 4 out of the eight cores are boosting beyond the maximum advertised boost speed of 5 gigahertz that's not surprising as we know that the programmed if Max is 5050 megahertz but it's always nice to see a processor over deliver on its promise here is the Benchmark performance at stock here are the 3dmark CPU profile scores at stock when running prime95 small ffts with AVX 512 enabled the average CPU effect of clock is 4285 megahertz with 0.937 volts the average CPU temperature is 65.7 degrees Celsius the ambient and water temperature is 24.9 and 29.9 degrees Celsius the average CPU package power is 71.9 Watts when running Prime 95 small ffts with AVX disabled the average CPU effect of Glaucus of 4531 megahertz with 1.011 volts the average CP temperature is 75.7 degrees Celsius the ambient and water temperature is 24.8 and 29.9 degrees Celsius and the average CPU package power is 75.7 Watts now let us try our first overclocking strategy but before that make sure to locate the clear CMOS button pressing the clear CMOS button will reset all your bios settings to default which is helpful if you want to start your bios configuration from scratch however it does not delete any of the BIOS profiles previously saved the clear CMOS button is at the rear i o panel in our first overclocking strategy we make advantage of AMD exclusive Performance Tuning Technologies Precision boost overdrive 2 and Expo with the launch of Zen 3 AMD introduced an improved version of precision boost overdrive they call this Precision boost overdrive 2. this toolkit gives us manual control over some of the parameters that are governing the Precision boost to boosting algorithm Precision boost overdrive 2 builds on the PBO implementation of Zen 2. In addition to the platform overclocking knobs from Zen plus PPT TDC and EDC and processor overclocking knobs from Zen 2 boost override and scalar Precision boost overdrive 2 introduces curve Optimizer there are essentially three levels of precision boost Overdrive amd's stock values which can be set by disabling PBO the motherboard vendor values which are programmed into the BIOS to match the motherboard vrm specification and can be set by enabling PBO and custom values which the end user can program I explore the ins and outs of precision boost overdrive 2 tuning in my AMD rafale overclocking launch video in this overclocking strategy we're simply enabling PBO whereas in the next strategies we'll also start tuning with some of the PBO tools we rely on the motherboard's pre-programmed PBO parameters by enabling Precision boost overdrive we find that the following values have changed for previous ryzen CPUs increasing the platform boost parameters substantially impacted the performance especially on higher core counts CPUs for Horizon 7000 X Series processors however amd's default platform parameters are relatively unconstraining for the 7800x3d it's clear that the platform boost limiters are not a constraining factor during a prime 95 non-avx workload we see that the maximum values for PPT TDC and EDC are 175 watt 60 amps and 60 amps respectively the main limiting factor for the 7800 x3d is the maximum allowed voltage of around 1 volt under a high load Expo stands for AMD extended profiles for overclocking it's an AMD technology that enables ubiquitous memory overclocking profiles for AMD platforms supporting ddr5 memory Expo allows memory vendors such as g-skill to program higher performance settings onto the memory sticks if your motherboard supports XPO you can enable higher performance with a single bios setting so it saves you from a lot of manual configuration while our memory kit is rated at ddr5 6400 I had to run it at ddr5 6200 because higher frequencies weren't stable with this particular CPU upon entering the BIOS go to the extreme tweaker menu set AI overclock tuner to Expo 1. set memory frequency to ddr5 6200 enter the Precision boost overdrive submenu set Precision boost overdrive to enabled then save and exit the BIOS we use the xiaomino Boost curve on Super PI 32m to check the cpu's Boost behavior and per core maximum effective clock frequency since enabling PBO doesn't alter any of the cpu's operating frequencies there's no difference to stock we rerun the benchmarks and check the performance increase compared to the default operation as expected enabling Precision boost overdrive does little to improve the system performance after all the CPU is primarily limited by the operating voltage not by any platform power parameters thanks to enabling Expo we still get a performance Improvement of plus 4.71 percent in geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4289 megahertz with 0.936 volts the average CPU temperature is 67 degrees Celsius the ambient and water temperature is 25.3 and 30.7 degrees Celsius and the average CPU package power is 84.8 Watts when running Prime 95 smaller 50s with AVX disabled the average CPU effect of clock is 4532 megahertz with 1.007 volts the average CPU temperature is 81 0.3 degrees Celsius the ambient and water temperature is 25.1 and 30.4 degrees Celsius and the average CPU package power is 89.1 watts in our second strategy we leverage the Asus x3doc profile that's embedded in the Bios why recently Asus has relied almost exclusively on their AI overclocking technology to provide a means for automatic overclocking Asus has a long history of providing customers with easy paths to extra performance those easy paths typically consist of having hard-coded bios profiles which the user can enable with a single click of a button the x3d OC profile is a return to this old-fashioned style of overclocking the profile uses a synchronous e-clock to overclock the ryzen 7 7800 X3 processor we'll get back to how this works later in this video for now it suffices to say that the profile sets the e-colic frequency to 104 megahertz and this overclocks rcpu by four percent note that the x3d OC profile does not adjust the Precision boost power limits so you want to enable Precision boost overdrive and ensure the PPT TDC and EDC are set accordingly to maximize the performance upon entering the BIOS go to the extreme tweaker menu enter the overclocking presets submenu select load x3doc profile leave the overclocking presets submenu set AI overclock tuner to Expo 1. set memory frequency to ddr5 6200 enter the Precision boost overdrive submenu set Precision boost overdrive to enabled then save and and exit the BIOS we use the xiaomino Boost curve and Super PI 32m to check the cpu's Boost behavior and per core maximum effective clock frequency the x3d OC profile increases the Precision boost frequency by about four percent thus our new fmax is 5250 megahertz this overclock translates nearly one to one to both the Boost curve and the per core maximum effective clock frequency the Boost curve now runs from 4852 megahertz to 4668 megahertz and we find that 4 out of our eight cores are now boosting Beyond 5.2 gigahertz in light workloads we rerun the benchmarks and check the performance increase compared to the default operation with a four percent CPU overclock the performance increased by about four percent in all of our benchmarks including the single threaded workloads we now have a maximum performance Improvement of plus 8.42 and geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4446 megahertz with 0.935 volts the average CPU temperature is 69.1 degrees Celsius the ambient and water temperature is 25.7 and 31 degrees Celsius the average CPU package power is 88.1 Watts when running prime95 small ffts with AVX disabled the average CPU effective clock is 4700 megahertz with 1.004 volts the average CPU temperature is 83.6 degrees Celsius the ambient and water temperature is 25.4 and 30.8 degrees Celsius the average CPU package power is 92.1 watts in our third overclocking strategy we will use the curve Optimizer tool included in the Precision boost overdrive 2 overclockers toolkit as I mentioned already curve Optimizer is a very important new tool included in the Precision boost Overdrive to toolkit curve Optimizer allows us to fine tune the vft curve of every core inside our CPU the vfd curve is a factory fused curve that defines what voltage is required to run a CPU at a certain frequency and a certain temperature the higher the frequency or the higher the temperature The More Voltage you need curve Optimizer adjust the vft curve by offsetting the voltages of the factory fused vft curve by setting a positive Offset you can increase the voltage Point conversely you decrease the voltage Point by setting a negative offset you can offset the entire curve by up to 30 steps in a positive direction and up to 300 steps in a negative Direction the traditional approach of a ryzen overclocking is to use a negative curve Optimizer two things happen when you do that first you tell the CPU that it needs less voltage for a given frequency and as a consequence at a given voltage it can apply a higher frequency second the CPU temperature will be lower because you use less voltage at a given frequency that extra thermal Headroom will also encourage the Precision boost algorithm to Target higher voltages and frequencies as I mentioned already curve Optimizer is available on a per core basis and that gives us a tangible benefit because some cores overclock better than other cores however for this OC strategy I will stick with an all core curve Optimizer the manual tuning process for curve optimizing can become quite convoluted because it spans a wide range of scenarios from single light threaded workloads to heavy all core workloads my particular process for curve optimizing this ryzen 7 7800 x3d was as follows in my case I used an all core curve Optimizer of -35 I will show you the bio settings in a minute but first please note that these values the curve Optimizer values are very CPU specific and the optimal values for your CPU may be substantially different than the values that I've used for this CPU upon entering the BIOS go to the extreme tweaker menu set AI over clock tuner to Expo 1. set the memory frequency to ddr5 6200 enter the Precision boost overdrive submenu set Precision boost overdrive to enabled enter the curve optimizer submenu set curve Optimizer to all course set all core curve Optimizer assigned to negative set all core curve Optimizer magnitude to 35 then save and exit the BIOS we use the xamino Boost curve and Super PI 32m to check the CPU boost Behavior and the per core maximum effective clock frequency while curve Optimizer doesn't increase the cpu's maximum boost frequency it does push the CPU to run at higher frequencies we find that the Boost curve has risen by about 200 to 300 megahertz compared to stock that every single of the eight cores now boost to 5050 megahertz that's 50 megahertz higher than the AMD advertised boost frequency of 5 gigahertz talk about over delivering on your promise we rerun the benchmarks and check the performance increase compared to the default operation curve optimizing this Horizon 7 7800 X3 processor surprisingly effectively extracts more CPU performance while unlike with the LC profile we can't increase the maximum boost 3 frequency in medium to heavy workloads curve optimizing pushes the CPU frequency higher than the x3doc profile hence we see a nice performance Improvement in most benchmarks we get the maximum performance Improvement of Plus 9.19 in geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4538 megahertz with 0.915 volts the average CPU temperature is 67.1 degrees Celsius the ambient and water temperature is 25.6 and 30.8 degrees Celsius the average CPU package power is 85 Watts when running prime95 small ffts with AVX disabled the average CPU effect of clock is 4800 megahertz with 0.986 volts the average CPU temperature is 81.5 degrees Celsius the ambient and water temperature is 25.6 and 30.9 degrees Celsius the average SCP package power is 89.1 Watts in our fourth overclocking strategy we will Leverage The Return of e-clock mode e-clock stands for external clock and is exactly what the term suggests we can use an external clock for the reference clock this was previously available on a ryzen 2000 pinnacle-rich CPUs but was removed afterward until now the standard Raphael platform has a 48 megahertz Crystal input to the integrated cgpl clock generator the cgpl then generates a 48 megahertz clock for the USB PLL and a 100 megahertz reference clock 40 fch which contains the cclk PLL for the CP cores and several SOC plls the external clocks are inputs to the fch there you can configure how you want to use the external clocks Raphael supports up to two external clock modes they're called e-clock zero mode and e-clock one mode and e-clock a zero mode an external 100 megahertz reference clock is used for both the CPU and SOC plls in other words it's a reference clock that affects the CPU core clocks as well as the pcie and SATA clocks and e-clock one mode there are two distinct external 100 megahertz reference clocks one clock provides the 100 megahertz input for the CPU PLL and another provides the 100 megahertz reference clock for the so or cplls in previous scatter Venture guides you know the ones before a ryzen 7000 I refer to the practice of using reference clock overclocking as super charging PBO but unlike previous ryzen processors reference clock overclocking is very well supported on the ryzen 7000 CPUs and it provides us with a viable path for overclocking the overclocking strategy with e-clock is the polar opposite of what we are used to with ryzen CPUs OC strategy number three shows that ryzen overclocking is typically done with a negative curve Optimizer that pushes the Precision boost algorithm to reach higher boost frequencies with e-clock we still build on the fact refused vft curve but adjust the frequency by adjusting the reference clock for example if the Precision boost has a vft point for 4500 megahertz at one volt at 50 degrees Celsius with an e-clock of 105 megahertz the actual point will be 4725 megahertz at one volt at 50 degrees Celsius the default voltage for this vft point won't suffice for stable operation so counter-intuitively we use a positive curve Optimizer to increase the voltages of the vft point for example a plus 30 curve Optimizer may increase the voltage by 150 millivolts thus the resulting vft point will be 4725 megahertz at 1.15 volt at 50 degrees Celsius note that the voltage increase is still subject to the Precision boost limiters the maximum voltage for a 7000 X3 processor is 1.2 volt regardless of the curve Optimizer setting suppose curve Optimizer doesn't provide you with sufficient additional voltage in that case you can always add a voltage offset via the vram controller configuration one more critical point e-clock also affects the maximum frequency ceiling with an e-clock of 105 megahertz the newly programmed if Max 40 7800x3d is 5.3 gigahertz if that's too high for your CPU you can always reduce the f-max by setting a negative CPU boost clock override the manual tuning process for using e-clock reference overclocking can become quite convoluted because it spans a wide range of scenarios from single threaded light workloads to all core heavy workloads the process that I followed for this ryzen 7 7800 x3d was as follows in my case I used an e-clock of 107 megahertz and a curve Optimizer setting ranging from -5 on core 6 and plus 10 on core 3. I'll show you the BIOS configuration in a minute but first please note that these settings are very CPU specific and the optimal values for your CPU May differ substantially upon entering the BIOS go to the extreme tweaker menu set AI overclock tuner to Expo 1. set ecoc mode to asynchronous mode set bclk to frequency to 107. set memory frequency to ddr5 6200 enter the Precision boost Overdrive submenu set Precision boost overdrive to enabled enter the curve Optimizer submenu set curve Optimizer to per core set Core 1 and core 3 curve Optimizer assigned to positive set core one curve Optimizer magnitude to 5. set core 3 curve Optimizer magnitude to 10. set core 6 curve Optimizer assigned to negative set core 6 curve Optimizer magnitude to 5. then save and exit the BIOS we use the xiaomino Boost curve and Super PI to check the CPU boost behavior and per core maximum effective clock frequency by setting the e-clock frequency to 107 megahertz the new maximum boost frequency increased to 5.4 gigahertz all CPU cores can achieve an effective clock frequency above 5.3 gigahertz two cores almost hit 5.4 gigahertz we also find that the one thread boost is now over 5 gigahertz and the Boost curve has increased by 250 to 350 megahertz compared to stock we re-ran the benchmarks and check the performance increase compared to the default operation as I've demonstrated in plenty of scatter Venture guides combining Precision boost overdrive with asynchronous e-clock has proven to be the most complex yet most effective OC strategy for ryzen 7000 CPUs generally we get the most significant performance uplift in single threaded and all core workloads that is exemplified with this 7800 X 3D as we see a plus seven percent Improvement in single threaded workloads and a maximum performance Improvement of Plus 10.71 in geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effect of clock is 4593 megahertz with 0.932 volts the average average CPU temperature is 71.1 degrees Celsius the ambient and water temperature is 26.5 and 31.2 degrees Celsius the average CPU package power is 90.2 Watts when running Prime 95 small ffts with AVX disabled the average CPU effect of clock is 4855 megahertz with 1.001 volts the average CPU temperature is 86.9 degrees Celsius the ambient and water temperature is 26.5 and 31.8 degrees Celsius the average CPU package power is 94.4 Watts in our final overclocking strategy we will pursue a manual overclock and that may come as a surprise to some of you because officially ryzen 7000 x3d CPUs do not support OC mode in fact if you go into the BIOS you'll see that there's no way to manually set a CPU ratio however we can mimic OC mode by disabling the Precision boost technology so the CPU works at its base frequency of 4.2 gigahertz then we can use a synchronous e-clock to overclock our CPU as if we were in OC mode do note though that by disabling Precision boost we also lose the benefit of that really high single threaded boost frequency so whereas the 7800 actually can boost to 5050 megahertz when Precision boost is enabled in our manual overclock the maximum boost frequency will be our fixed frequency now to understand how we can overclock this 7d800 xtd in manual mode Let's have a look at its clocking and voltage topology the clocking of AMD Rafael is similar to the previous generation of Zen 3 Vermeer desktop CPUs the standard rafale platform has a 48 megahertz Crystal input to the integrated CG PLL clock generator the cgpl then generates a 48 megahertz clock for the USB PLL and a 100 megahertz reference clock for the fch which contains the CCL kpl for the CPU cores and several SOC plls the cclk PLL 100 megahertz reference clock drives the 200 megahertz vco which is then multiplied by an FID and divided by a did as a whole this provides CPU clock frequency granularity of 25 megahertz as with Vermeer each CCX has its own PLL with the cores within that CCX running at the same frequency in a typical operation all cores within as CCX will run at the same frequency the effect of clock will differ if the core is in a different P state the soc plls include a wide range of plls on the i o die the ones most relevant for overclocking are f-clock u-clock m-clock and gfx clock the soc plls are not particularly relevant for manual CPU core overclocking Raphael supports up to two external clock modes they're called e-clock zero mode and e-clock one mode and e-clock one mode one clock provides the 100 megahertz input for the CPU PLL and another provides the 100 megahertz reference clock for the soc plls from the voltage topology perspective zen4 or Raphael is very similar to zen3 Vermeer the processor still relies on a combination of internal and external power supplies to regulate the voltages there are four primary power supplies from the motherboard vrm to the processor the vddcr voltage rail provides the external power for two internal voltage Regulators vdd CR CPU and vddcr V DDM vdd CR CPU provides the voltage for the CPU cores in the CCX on CPUs with multiple ccxs each CCX has its own vddcr CPU voltage rail but the voltage will be identical the voltage rails can work either in regular or bypass mode but it is always in bypass mode on Raphael that means the voltage is always equal to the vddcr external voltage the vddcr voltage rail can be directly controlled via the svi 3 interface by CPU configuration the end user can also directly control the vddcr voltage rail as the Motherboard BIOS provides the means to program the voltage regulator directly choosing the appropriate manual voltage will always be a trade-off between increasing the overclocking Headroom dealing with the thermal issues or thermal challenges related to increasing the voltage and of course consideration of the CPU lifespan it's with that last thought that we kick off our menu manual tuning process ultimately the thermal solution will be our main limitation and that's because power scales exponentially with voltage and temperature scales somewhat linearly with power consumption the limiting factor for our voltage will be our worst case application or worst case stress test scenario in this case I pick my worst case scenario to be the same as any of the previous overclocking strategies Prime 95 small ffts with AVX 512 enabled the next step is to check the maximum temperature when running our workload and increase the operating voltage if there's thermal Headroom once we know the maximum voltage we can tune the e-clock frequency until the applications show instability in this case we end up with an e-clock frequency of 114.3 megahertz at a voltage of 1.035 volt that results in a CPU frequency of 4.8 gigahertz upon entering the BIOS go to the extreme tweaker menu set AI over clock tuner to Expo 1. set e-clock mode to asynchronous mode set bclk to frequency to 114.3 set memory frequency to ddr5 6200 set the CPU core voltage to manual mode set CPU core voltage override to 1.035 then save and exit the BIOS we use the shamino Boost curve and Super PI to check the CPU boost Behavior and the CPU per core maximum effective clock frequency when we perform a manual overclock with a fixed frequency unsurprisingly the frequency is fixed across the board and for each core we rerun the benchmarks and check the performance increase compared to the default operation as expected we see a performance deficit against stock performance in single threaded applications as manual overclocking loses the benefit of the Precision boost 1T frequency in multi-threaded applications however we see a nice performance up lift of up to Plus 8.63 in geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4799 megahertz with 1.022 volts the average CPU temperature is 85.7 degrees Celsius the ambient and water temperature is 26 and 31.9 degrees Celsius the average CPU package power is 101.6 Watts when running Prime 95 small ffts with AVX disabled the average CPU effect of clock is 4794 megahertz with 1.028 volts the average CPU temperature is 91.8 degrees Celsius the ambient and water temperature is 26.8 and 30.4 degrees Celsius the average CP package power is 91.8 Watts in this overclocking strategy I've shown you how to think about or how to go about manually overclocking your 7800 x3d but of course if you don't care about prime 95 with AVX 512 enabled stability you can always pick another test as your worst case scenario for example in Final Fantasy 15 I could run 5.1 gigahertz with 1.15 volt and a maximum temperature of 70 degrees Celsius however I must emphasize that the ryzen 7 7800 x3d processor is very sensitive to voltage even if you increased the voltage a little bit you will very quickly run into thermal issues in my experience anything over 1.15 volt isn't really usable in a daily situation as you will very quickly hit the TJ Maxx the ryzen 7 7800 X3 may also have a sufficient Headroom to satisfy the competitive overclockers and benchmarkers I could push this CPU up to 5.6 gigahertz with water cooling all right let's wrap this up at the very beginning of this video I said it was ironic that the 7800 X3 processor turns out to be the most tunable x3d processor yet and I stand by that comment given all of the overclocking strategies we went through in this guide and how locked the 5800 x3d was so we have to give credit and say thanks to the folks at AMD that decided to give a little bit more performance leeway for the ryzen 7000 x3d processors I genuinely enjoyed exploring all the various ways that we could extract more performance out of this CPU and I really feels that the more you go down the rabbit hole the more effort you put into fine tuning the more extra frequency and performance you can find but I must again raise your awareness or Point your attention to the fact that voltage is the real main danger for the 7800 x3d realistically I don't think any voltage above 1.15 volt is going to be good for your CPU good in a sense that it will not cause you to hit TJ Maxx anything above 1.15 volt with any kind of a medium to high workload really pushes your CPU to the you know to the maximum temperature if you go beyond 1.15 volt then thermal choking might generally damage your CPU so be very careful if you want to go over 1.15 volt anyway that's it for me today I thank you for watching and I thank the patrons for their support as per usual I will put up a written version of this video up on my blog if you want to go through the bio settings or check the performance results if you have any questions drop them in the comment section below and see you next time foreign [Music]

An interesting video showing an example of what can be possible overclocking the 7800x3D. I'm going to be upgrading from an OC'd 8700k to this and wasn't familiar with what sort of possibilities there were with getting more performance out of the CPU.

I was under the impression that the CPU would be pretty "locked down" (again, I don't have much experience with OC'ing in the AMD ecosystem) so it's awesome that there's potential!

Best of luck to everyone trying to get it tomorrow!

EDIT: Was able to snag a 7800k this morning on AMD's site a minute before it sold out - apparently people still have had luck on Newegg setting their option to "pickup" in the US. The CPU doesn't come in a week so I'd love to benchmark some comparisons between the two chips if there's any interest (especially in VR).

[u/NateST]

A few AMD boards have an eclock generator, which allows the base clock to be adjusted for oc rather than the multiplier. Make sure you have this option if you're thinking about buying this with oc in mind.

[u/frissonFry]

This video shows that curve optimizer is still probably the easiest way to extract the most out of the chip, safely.

[u/Background_Summer_55]

Any ideas which are the cheapest boards that support overclocking with clockgen? Or is the asus rog for 600bucks your only option?

[u/metahipster1984]

Anyone know whether an Aorus b650 Elite AX could theoretically do this?

[u/MerAnd84]

The parameter “Max CPU Boost Clock Override” of the PBO2 allows to increase the max boost of the 7800x3D or not? SkatterBencher always skipped this option: why?

[u/p1rate88]

Hm. I upgraded from 7700x and now getting lower results in 3dmark cpu test. Previously I had AI overclocking enabled in my MB Asus B650E-E but now it seems like it’s not working anymore. Anybody else experiencing the same issue?
