Hey, guys, TECHOSAUR here. For the last few days I've been quite busy, Undervolting my 14700k
while keeping performance in mind. As you know, the 14700k
got 4 more cores than the 13700k, but that also introduce a challenge
to cool it down. So in this video I'll guide you through
how to run it consistently at 5.6GHz across all P-cores And 4.3GHz on all E-cores while still maintaining
optimal thermals and power saving. The motherboard I'll be using
is ASRock Z790 PG Sonic, but most of those techniques are applicable in other models
by ASRock as well as other brands. So you can follow along and should you need any help, please don't
hesitate to ask in the comments below. So with that being said,
we are now ready to start our tweaking. Let's get started. Here I am in the BIOS settings
and by default it Boots to the EZ mode,
which basically shows you useful stuff such as BIOS version, CPU specs,
and DRM information. For example,
I'm using 2 Kingston sticks of 16GB DDR5
running at 7200MHz. By using the XMP profile, it also shows you
the storage configuration and fan status. For CPU cooler I'm using EK-Nucleus 240mm AIO Up here, It shows you the current temps of the CPU and motherboard
as well as CPU voltage. So I think I covered everything
I wanted to show here. We can now head over to the advanced mode
by clicking here or pressing F6. Now let's go to the OC Tweaker tab. And here
I wanted to show you a new feature that wasn't present until recently,
which is the CPU indicator. This shows you the quality of the P-cores
and the E-cores. And according to the statistics,
the average P-core quality is 82, Top 1% is 90, and Top 10% is 86. Mine is below the average. But I think it counts
also for the 14900k. So anyway, you can check yours
and hopefully if it was higher you might be even to undervolt it
more than I did. I just wanted to clear that point. Now we can go back and starting our Tweaking
stuff in the CPU configuration for CPU P-core ratio. I have it
set on all core with the ratio of 56. Now you can also know which
P-cores are the fastest by changing it to Specific Per Core For example,
mine is Core 4 and Core 5 As you can see, 56/56 while for other P-cores it's 55
and I set it to 56. This way you'll know your fastest
P-cores. As for the AVX2 ratio, I dialed it down by two points,
making it 5.4GHz, as AVX workloads are heavier
and cause more heat. For the E-cores, I have it on All Core with a ratio of 43. That's the maximum stable
I could get, as a bonus tweaking. I changed the BCLK frequency to 100.28. Scroll down here and I want to show you that
I have disabled UnderVolt Protection. This eventually will let you
to Undervolt in Intel XTU Tool. So if you are interested in that,
make sure to disable it here. I also have all intel technologies
enabled like Speed Step, Turbo Boost, Speed Shift,Turbo Boost
Max 3, as well as Thermal Velocity. By default they are all enabled
except for the Dynamic Tuning Technology in a previous video,
I showed you as the uplift it makes for the 14700k,
so make sure to enable the DTT technology. Let's scroll down and here
I have the CPU Tj Max Set as 100
as well the fast throttle threshold. The PL1 I have is 265 and the PL2 as 270, but for the majority of time
it wouldn't hit those limits. But just to make sure it doesn't
lower core ratio due to power limit. So now that we are done from here,
we can go to the DRAM configuration. If you are using an XMP supported
RAM, you can enable the profile here. I also wanted to show you
some additional features. If you scroll down to the bottom,
here you can make sure to enable the ASRock DRAM
frequency optimization. I also set the MRC training time
to slowest to enhance stability and enable MRC training on warm boot. This would ensure good memory
training at all time. Now exit that menu
and We’ll head now to the voltages area for the CPU Core/Cache Voltage, I have it set on auto and the Load Line
Calibration to Level 3, In order to have a balance
between Vdrop and thermal. In addition to that, I want to show you
that I have the IA AC load line and the IA DC load
line both set to auto, For me They came in this way. Just wanted to point that out in case
you have them modified in a different way. For my tweaking,
I won’t change them from auto. Now exit that menu and go to the FIVR
configuration, which basically How we’ll
do the Under Volting. Select the V/F Offset mode from legacy
to selection. And here you can see different
ratio points making a curve. It's not impossible
to tune it, with some trial and error. You will get it right because I am not quite certain
if my curve points will work for everyone. But anyway you can give it a try
and see for yourself. I have it set as the following: Ratio 8 -500. Ratio 14 -400. Ratio 24 -300. Ratio 34 -200. Ratio 43 -185. Ratio 51 -175. Ratio 53 165. Ratio 55 -155. Ratio 56. -150. So the higher the ratio,
the less negative offset we apply. For me,
this technique is way more efficient than using the global voltage as in that
one, you can't go below negative hundred. And in this way we can reduce thermals in a very good way,
as you will see later on. You can also use the retrieve VID
as a refinance to get an idea. It's quite handy, but as they write
here, it's not very accurate. So make sure to not rely so much on it. So with the CPU under volting done. For the rest of voltages. I have them all on Auto. Other Settings I would like to show
you are found in the Advanced tab. So go there. Starting with CPU configuration, here,
I enabled all the C-states to save more power when system is idle
and also to lower thermals. I also have Intel Virtualization
Technology to OFF. Now go back and go to chipset
configuration. Here I have the VT-d to disabled,
which is linked to Intel virtualization. Also make sure you have above 4G decoding
and to enable Clever Access Memory to enable resizable BAR. We’ll skip the tools tab
and head straightly to the hardware monitor where you can change the fan mode, setting it from standard
to performance depending on your need. Now we can head over to the Boot tab and here
I have Fast Boot to Ultra Fast. A nice feature
I like is the Boot Failure Guard Count basically if the system fails to Boot, it would revert back to previous settings
after number of attempts. I've set mine to two, Another thing
I want to point if it was stable enough. You can save your profile in the OC Tweaker down here. So I think we are good to go. We can now head over to the array of
stability tests and benchmarks I've prepared so you can get an idea of the results. See you there. First we’ll start with Cinebench
multi-core and single core test. It's quite impressive. We managed to achieve a score of 37,000
in multi-core and 2212 in single core. However, it's early to call it
a stable system without doing an OCCT test. And we're going to test it
with three different workloads which are SSE, AVX2 and AVX512. As for the data set I'll be using,
it will be small in order to maximize the stress
on the CPU and also for the mode I’ll choose the extreme one. Also to maximize the stress on cooler
and the CPU. So let's begin. It passed all three tests flawlessly. But even so, we'll move on to AIDA64
stability test and run it for a minimum of one hour. Here it also manage the test
without any issues as well. And now for our final test, We’ll use Y Cruncher
Component Stress Tester, Let's Go! Having passed
this test too, makes me quite confident that our tweaking caused zero
instability. It's really a moment of joy whenever
you see your system stable after tuning. But I also wanted to go through various metrics
gathered from the entire set of tests. So the maximum VID recorded was 1.229V
with all P-cores reaching 5.6GHz
and the E-Cores reaching 4.3GHz. Regarding temperatures,
the peak was 88 degrees Celsius, which is well within the safe
range for Intel CPUs. Under all this heavy stress. We also stayed within the defined power
limits without any thermal throttling. As for the maximum Vcore it's 1.264v. So overall, given that we are using a 240mm AIO Cooler Those results are very promising. It appears that Raptor Lake
refresh CPUs can handle a significant under volting even at high clock
speeds, for gaming benchmarks. I prepared a set of different games. As for the GPU I'm running,
it's Intel ARC770. It might bottleneck it a bit, but
I'll do my part and set it to all 1080p. Low Settings to ensure it's not. Let's check it out. So as you have seen, even in games, there's a quite significant drop
in temperature and power consumption. Yet performance remains superior. It might even be better given that the GPU
might have caused a bottleneck in certain times. I really hope that this guide will help anyone
looking to optimize their 14700k. If you found it helpful, please give it a like and subscribe
