AMD Ryzen 3000 Memory Benchmark & Common RAM Mistakes (fClock, uClock, & mClock)

memory speed on rising has always been a hot subject with AMC's 1000 and 2000 series CP is responding favorably to fast memory while at the same time having difficulty getting past 30 200 megahertz in Gen 1 the new rise in 3,000 chips officially support memory speeds up to 3,200 megahertz and can reliably run hits up to 36 hundred megahertz with extreme overclocks up to 50 100 for most people this type of clock isn't achievable but frequencies in the range of 3200 to 4000 are relatively easily done the looser timings then become a concern today we're benchmarking various memory kits at X and B settings with a rise in memory DRM calculator and with manual override overclocking we'll look at the trade-off of higher frequencies versus tighter timings to establish the best memory solutions for

lot on the motherboard there's some testing parameters that are important so to kind of cover that stuff briefly first keep in mind that with memory it's really it is primarily the motherboard and the BIOS that defines how it performs the memory to an extent does matter obviously it needs to be able to hit the timings on the frequencies that give the performance that you might want but also only so much data can fit into XMP you can't fit all the tertiary timings you can't fit all the secondary timings even and there's even unsurfaced timings which we talked about in our first how memory timings work video there are surface timings that won't even appear in the motherboard BIOS for you to tweeks if even if you wanted to so motherboards matter a lot and we ended up testing two boards for this instead of just using one because we were a little concerned that if we used one we might see a scenario unfold that might not be true on another so he is the gigabyte X 570 or s master that's the board we've used for most of our reviews we wanted consistency there so we could compare the data three views and we also use the msi god-like motherboard the x5 sony godlike which is basically the best memory overclocking motherboards for Rison that exists it did a 5100 in the early demo so we trusted that one to have good memory timings but it does matter if the kits you're using or on the QV else - I'd be the qualified vendor list so one of the biggest things before we even get into the data is when you're building a system for any Intel AMD doesn't matter for any platform you should look at the motherboard you're considering buying check the qualified vendor list they call it a qvl and make sure the memory you want is on there and if it's not it means it hasn't been independently qualified by the motherboard manufacturer so that's on the motherboard maker they go out they ask for the kit or buy it from the memory maker and then they test it make sure it works and if it's a popular kit like a lot of these g.skill tried and z ones are the motherboard manufacturers will also go through and sort of pre configure how the timings are adjusted in BIOS so that's all really important to know for this as far as our testing today we did a lot with XMP so this is sort of like a memory review in that we took kits we applied XMP and we tested them onto motherboards just to have the data there in case we needed two sets of data if one looks weird or something and that'll help you figure out the standard scenario which is I want to buy a kit of memory for Rison 3000 I don't want to do any work I don't apply XMP so we've answered that with this set of kits obviously a lot more out there and then we also did manual tuning we did this two ways one is what the at this point pretty popular and well-known rise in RAM profiling tool which it's a dram calculator they call it it's a software solution you input a good amount of data so it's it doesn't do any work for you you just put the data in of regarding the kit that you have and it spits out a bunch of timings it recommends and then you have to write those down screenshot or whatever and manually input them in BIOS and then we also did manual overclocking which we've got some experience with not great at it but pretty good for for something like this so we did manual tuning beyond the DRAM calculator to see if it mattered anymore and for all of that we use only the X 570 godlike because we just we didn't want to fight with a board more than we had to doing memory overclocking is hard enough once don't really want to do it multiple times so that's the outline for how we did the testing and there's more in that article below but all the tests were run in dual channel with only two sticks we did a gigabyte sticks each in the recommended memory slots for the board and we abbreviated our usual CPU testing suite to only 1080p gaming the 1440p stuff doesn't really matter the special test mentioned we run because of the way AMD handles memory clocks past 30 600 megahertz normally the M clock or memory clock the u clock or the memory controller clock which is on the CPU and the F clock or the Infinity fabric clock are run at a 1 to 1 to 1 ratio for example 1600 megahertz for all 3 when a 30 200 megahertz X MPA is supplied would be one of the common scenarios remember running double data rate memory at 3200 mega transfers per second means an actual M clock of 1600 megahertz because DDR memory can transact on the rising and the falling edge of the clock with memory speeds greater than 3600 megahertz or M clock greater than 1800 megahertz F clock caps at 1800 megahertz on the AMT Rison CPUs and you clock switches to a 1 to 2 ratio with M clock here's the quote from AMD to clarify further they said enabling 2 to 1 mode crosses clock domain boundaries imparting a dram latency penalty of approximately 9 nanoseconds that may be overcome with additional memory clocks higher CPU frequencies or sub timing adjustments in other words 2 to 1 mode Hertz performance but not so badly that it can't be made up for elsewhere we took the G scale 38 66 kit and ran it on the godlike board 5 different ways straight XMP XMP with memory set to 3,800 and F clock set to 1900 manually XMP with the memory set to 3800 F clock 1900 M clock to u clock ratio force to 1 to 1 ie everything running at 1900 megahertz and then again with everything running at 1900 megahertz and DRAM timings optimized by the DRAM timing calculator which is really us putting in the numbers that it tells us to put in and so you know with primary timings of 16 16 16 32 and then finally at 4200 with the highest clocks and tightest timings we could manage without blowing out the voltage the thirty two hundred megahertz CL 14 tried in Z RGB kit used for this testing is the same that we used for CPU testing but the results aren't directly comparable since we only applied Aksum P for this test while we normally specify timings manually to ensure consistency between boards and improve performance for benchmarks and reviews on the screen now are the times we used initially when optimizing the 38 66 kit to run at 38 hundred megahertz instead of 38 66 note that the kit we used was actually single rank and the calculator would have output slightly tighter timings if we had specified that but the numbers from this profile were still significantly better than stock we did some further tuning here too so for example we tried setting the frequency to 42 hundred megahertz it worked no problem this was on a 38 66 megahertz kit so for this we end up running 4200 slightly looser timings but still tighter overall and it worked it ran the main things we changed were TF aw or for active window so we set that down to 24 and that was from something closer to like 40 from the DRAM calculator output and we started seeing diminishing returns below 24 where it could technically run at 20 or 22 but stability became suspect and the results start getting worse in the tasks we were using we also set TR FC or the refresh cycle to 280 and refresh cycle is pretty important especially for things like gaming benchmarks 3 marks a great example of something that's really sensitive to our FC and then we ran into an interesting challenge beyond that so to further improve the timings which we have done again in our competitive overclocking streams to further improve timings we'd have to push the SOC voltage higher and the memory voltage higher to get stability the big and interesting problem with this is that the more voltage you push to those things like especially SOC which is part of the rise in CPU package the more voltage you push there the higher the heat is on the processor and even though it's not the part of the processor that contains the physical cores however many that may be 812 it is still contributing heat to the overall processor package and because Verizon is so temperature dependent where every couple of degrees you start dropping a bit more off the clock you actually end up in a scenario where yes it's possible for us to tune the memory further with this particular kit which is rated at 3600 but we can run above 4,000 it's really damn good it's possible yes but pushing more voltage through the CPU without changing the cooling solution means the CPU gets hotter and so those gains from tightening the timings further by increasing voltage are lost because the CPU is starting to drop clocks now so there's a really interesting balancing act there that we don't normally have to account for because typically a CPU just it stays at one setting and doesn't move further SOC voltage to pay on the board but SOC voltage if increased past one point one volts with some biases will drop the PCIe generation from gen 4 to Gen 3 now it's not particularly relevant unless you're running a Gen 4 SSD but it is something to note so if you do need to push up for stability it might not be a good idea if you need Gen 4 and if your board has that same results from increase in that suze voltage civilization is first up with an AI benchmark scored on average turn completion time rather than fps this benchmark has proven mostly indifferent and these high core counts but memory speed is a slightly different story the twenty four hundred megahertz G scale kit scored a bit better on the gigabyte master that on the god-like but as the lowest frequency can't we tested both results are predictably right at the bottom of the chart more surprisingly the 3200 guile kit is also near the bottom below the 3200 vengeance healthy x kit with loose or primary timings and even below the 3000 megahertz ALP acts in 2666 Crucial Ballistix the elite kits we should note that AMD provided the guy hit with the RF 5 CPUs on a previous review cycle so you'd hope it'd be better but part of this depends on if the motherboards tuned for it the middle of the chart is populated by the greater than 3600 kits running with Auto settings so that's two to one mode with 1800 F clock while the 3,200 and 3,600 kids top the chart for straight XMP results that includes the 3600 CL 16 Triton Zinio and 3200 CL 14 Trident II RGB that we use in testing though we tune timings even more this backs up our decision to switch to Trident II RGB for testing instead of the 3200 vengence lpx kit as it should avoid bottleneck and while still retaining compatibility with the older risin generations that have limited memory compatibility that's the key but the 3600 g.skill Trident Zinio and 3,600 G skill tried indeed Royal kits were essentially tied although neo is specifically marketed as Rison compatible and has AMD logos on the packaging for the 38 66 try Danzig hit straight XMP it was clearly the worst of these high tier results and the result with optimized timings was the best followed closely by the 42 hundred megahertz results and the other two were tied in the middle so it seems that AMD may be right about 2 to 1 mode not being a huge deal Geoff's boosting F clock by 100 megahertz and lowering M clock by 33 megahertz to sync them both at 1900 megahertz had a more significant effect the 40 200 megahertz tests still had F clock running at its highest stable speed of 1900 so the clocks were distinct and the potential performance gained from the memory clock increase was cancelled out if we highlight the best and worst results here the bottom of the top maximum improvement potential was a difference of about a couple seconds 33 to 31.5 or so the dots between the best results and a 3200 CL 14 like Trident II RGB @ 32.2 seconds is about 2.2 percent this indicates that depending on memory price is a 3200 CL 14 kit may be a good choice to split the difference in cost the 4000 megahertz HyperX kit with CL 19 x proves unsurprisingly that latency matters for games more than just a higher frequency that's especially true with automatic adjustments rising 3000 makes when running memory faster than 3600 you'll notice going forward that the guy'll kit is always among the worst on the bench if not the worse on the bench but note one thing here after validating a few kits over this we also validated the guy'll kit to me it's numbers look the same after multiple reconfigurations and tests so this isn't just rerouting the tasks but actually rebuilding the system a few days later and doing it again it validated it perfectly on the gigabyte board meaning that the guy'll kit remained in exactly the same spot in the charts we then tested it on the MSI board and found that Emma sized board auto configured better timings than gigabyte did for this guy'll memory to significantly improve the performance it's an interesting example of how the motherboard matters more than just memory in some instances we'll show those lines where they were most significant which will be Tomb Raider and hitman at the end of all the other charts so if you want to see how they differ keep an eye out for those too at the end of this game chart section until then we'll just show the guile kit on the gigabyte board for simplicity and then we'll expand on and explore up a bit in the DX 12 games the next benchmark looks at GTA 5 at 1080p as with the civics test the 2400 G skill kit did the worst of the bunch thanks to the low frequency the guy hit did a bit better relatively outperforming the 2666 ballistics by 2.3 percent as expected the 36 hundred megahertz kids performed the best with straight XMP landing at about 108 FPS average and the two kits greater than 3,600 land in the middle of the chart and around 104 FPS average the tweaks 38 66 megahertz kits again fill the top including the 38 66 at 3800 mega Hertz CL 16 maxing out at up to 117 FPS average with the one to one to one ratio and optimized timings result averaging 12 percent better than the baseline XMP results about 104 FPS average for the same kit if anything this testing has made us more confident again in our choice for CBO testing versus the other kits on the chart here because well while retaining compatibility it does pretty well the 3200 Trident II RGB is keeping pace with a 3600 kits that we own anyway and that's without manual tuning that we do for the reviews in the 3200 CL 14 the 3200 Corsair Vengeance kit we were using previously isn't far behind but it is inferior the 4000 HyperX predator is suffering here and showing its weakness frequency and latency are two sides of the same coin and this is a CL 19 memory kit running at a frequency that rise in 3000 fully support so you get some changes in the other clocks the bottom of the top performance range is considerable in this game at 17.8% or 9.7% solely using XMP remember it's not just primary timings but all those tertiary and even unsurfaced timings that get sat on boot if the board hasn't been validated with a kit and the kit isn't on the QB LS there's a chance it'll be horribly automatically configured upon boot consider that the 3216 1818 LP x kit has outperformed the 3216 1616 dial kit so far it's clear that memory choice has a significant impact on performance and a lot of these kits are similar in price so you should check the qvl before buying something everyone 2018 benchmarks are next this lineup should be familiar by now twenty four hundred and twenty six sixty-six kits are at the very bottom the high frequency XMP kits are in the middle and the tuned at thirty eight sixty six kit is at the very top for once the forty two hundred megahertz overclock tied to the thirty eight hundred megahertz optimized result instead of falling slightly behind landing at 296 FPS average for a 10 percent improvement over base XMP results 268 FPS average the two to one and want Awan results remain almost identical to each other 0.1 percent performance is too variable here and unreliable for this level of granularity so we moved it from the plot to reduce confusion as the point 1 percent load data lacks consistency in the specific game and once you're down to memory instead of CPUs it just becomes pointless the wild card guile kit had another bad run here landing just above the 2666 result instead of with the other 32 hundred megahertz kids the improvement bottom to top of 17.2% which is pretty wild stuff without making any changes to the CPU or the GPU at all I think it's actually kind of insane that's the type of change you can get with like a massive GPU upgrade memory isn't usually at the top of the list when looking for FPS improvements but memory choice should not be made lightly especially now that memory isn't quite as overpriced as it has been in recent years shadow of the Tomb Raider finally shows a noticeable advantage for the 40 200 megahertz OC over the tune to thirty-eight hundred megahertz average with a 2.5 percent performance uplift for the higher clock speed moving 155 MPs average from 151 FPS average and a massive 16.3% improvement over XMP is 38 66 megahertz the 132 point nine FPS average for that 38 66 XMP result the AMD provided guile kit landed at the absolute bottom of the chart for the first time a significant step below even the 24 hundred megahertz G skill kit the range is a massive 41 FPS average or 36% improvement potential bottom to top the 3200 CL 14 kits can be seen as above average while maintaining relative affordability and compatibility although these days it is kind of hard to find 3200 CL 14 kits in the US at least so you may add up having to buy 3600 anyway just because it's more available and that seems to be what the memory makers are leaning towards so for Tomb Raider here's the big note on this one when retested on the msi board the guy old memory climbed to 130 FPS average 116 an improvement of 12 percent over the gigabyte board at the same memory we retested and validated this three times on the gigabyte board this is a motherboard tuning difference but because the memory isn't on the qvl it isn't really a problem it's not really a gigabyte issue because they never said it was rated to work with the board anyway hey man 2 is next and shows a much more pronounced spike and performance with memory tuning than the other results 4200 Hertz at 133 FPS average was the best overall plotting a 4.6 percent gain over the 3800 megahertz 1 2 1 2 1 CL 16 results 127 FPS average and a 21.6% improvement over the 38 66 megahertz XMP result of 109 FPS average all the other straight XMP results were fairly close at about 109 FPS to 149 PS average so nothing to stress about the improvement from 24 hundred megahertz g.skill to 36 hundred megahertz CL 16 neo was just 6.9% for instance so don't worry too much about this one the HyperX 4000 megahertz unit does a bit better here than some of the other games there's a massive 45% scale from worst to best in this benchmark thanks to the unusually bad score for guile but most of the results are clustered within 4 to 6 percent of each other like tomb raider hitman 2 also serviced the tuning between a messiah and gigabyte for the guile kit Imus I ran at 111 FPS average whereas gigabyte ran at 91 average with both tests validated and retested over a period of a few days apart the guy Auto timings were better configured on the msi board out of box again this is exactly why you should make sure the board and the RAM are explicitly friendly with one another just to avoid any kind of weird auto timing issues like we're seeing on the gigabyte board total war war hammer to his battle benchmark is next the battle benchmark for a total war Warhammer - is one where we see GB bottle back into a degree even at 1080p but it seems that there's some room for improvement with memory as well we're back to the x11 titles again in the 30 200 megahertz guile KITT has bounced back above the 2400 bagger Hertz Ripjaws but still not to the level of the other 3200 Hertz kids the tune 240 200 megahertz and thirty-eight hundred megahertz results at the top of the chart and are essentially tied down to even the point one percent lows and the average for the 4200 Hertz test shows a 7.4 percent increase in performance over XM peas 155 FPS average at 38 66 megahertz the manual tuned results shows slightly worse point one percent lows on average and this title is actually consistent in frame time performance so we trust the data here and it exits run - run variance within the testing this isn't most likely caused by some borderline instability in t RFC and TFA w-4 that manually tuned KITT doing a bit worse in the lows the last benchmark is the campaign test for Warhammer which is usually better at highlighting differences between CPUs and we have less reason to think that there's a GPU bottleneck in the scenario the tune 42 hundred megahertz and 3,800 Hertz results are still close here but the 40 200 megahertz average has a small 1.5 percent advantage instead of being completely tied but with a similar 7.6 percent increase over XMP this is the final game benchmark and the results have been shaken up yet again and that's possibly due to many of the results being practically the same the 3200 Trident II RGB kit and the gigabyte board is many places above the same kit MSI board on this charge but that's from a performance improvement of only 2.2 percent the 2666 crucial kit and the 24 hundred megahertz G scale kit are tied for last place while the guy'll kit performs as well as the 32 hundred megahertz lpx kit for once the 4038 66 kits put up a valiant fight here but we're still outmatched the 36 hundred megahertz kids running without any tuning beyond XMP talking conclusions then for anyone who isn't interested in manually tightening timings and adjusting voltages a thirty six hundred megahertz XMP kit or a high-quality thirty-two hundred megahertz kit is the obvious choice it'll come down to price availability in your region things like that thirty six hundred is the clearly defined limit of easy performance gains from memory frequency on Rison and we saw our thirty-two hundred megahertz CL 14 tried in Z RGB kit perform at nearly the same levels as our g.skill thirty-six hundred megahertz CL sixteen kits and most tests when using only XMP timings are important and that's where we've seen the difference for what it's worth we didn't see any glitches or huge performance losses past thirty-six hundred megahertz in any of these tests performance just sort of stops scaling or takes a minor hit infinity fabric clock like any other frequency on the CPU is going to be defined by silicon Madhuri luck of the draw so on platforms where F clock can be pushed a little higher than 1800 megahertz we could do 1900 on the CPU it may be worth considering one of those thirty 866 kits and running at 1900 for the F clock and then drop down thirty 866 to 3800 so you can run one one one for everything so from what we gather achieving the F clock at 1900 megahertz is relatively uncommon and pushing M clock isn't really worth it if it means giving up the one to one to one ratio so that's important as well it's really easy for you to go in there try to improve things and end up with numbers that are technically higher like frequency but actually hurt your performance so just be aware of that make sure you do testing before your changes and after times pi is a great way to test this CPU only and then 8 o 64 has a dram and cache test that you could use as well but we would recommend strongly using gaming tests not just the bandwidth because gaming matters if that's what you're doing further if you are pushing for higher F clock from what we've gathered from MSI it sounds like 1800 1833 is kind of where a lot of the CPUs will stop nineteen hundreds less common going over that is very uncommon so it is you know don't feel too bad if you can't get much higher Andy has decent plug-and-play support for kits that are greater than 3600 megahertz but making these kits actually perform better than their lower frequency tighter timing alternatives is pretty difficult and you start getting into fighting a lot for tiny gains and performance users will likely end up seeing greater performance gains from buying a trusted 3600 CL 16 kit and following the rise in dram calculated recommendations or learning how to tune it yourself then you would see from trying to run a higher frequency kit with XMP so that's the takeaway and then as far our sweet spot 3600 we suppose is in a good spot but 3200 CL 14 is also very good it's really close and a lot of those charts to the 3600 kids it is typically pretty affordable and readily available but depending on DRM price has changed so much these days that if it's a few bucks away from 3600 kit that's actually good you might as well go to 3600 and if it's a big gap 1020 dollars something like that it's really you're not losing the time by going 3200 TL 14 but that gives you a good idea of what you should buy based on your money available and that will cover it for this one thank you for watching subscribe for more you can go to store documents axis thot net to

this is why I need to begin my 3800 dream journey again even with 3733cl14 1.52v B-Die Chasing that 3800 always seems to always get me with the Dram Calculator perhaps now that I finally after so long found where power down mode was to disabled I can maybe stop getting 1 in 5 chances of computer not posting and resetting my bios. Regardless videos like these really make me want to try again. Even if it means days of trying...again...and again... -.- I spend way too much time trying. Perhaps ill just wait till after the boost behavior boosts patch comes out to try again since updating deletes all my timings which I pretty much have memorized now or take pictures of. x_X

Took a whole day to get to 3600cl14 with good timings. After some hesitation I tried 3800cl16 and got it to work after under an hour.

Is the Corsair Vengeance LPX 3200mhz/CL16 equivalent to the Crucial Ballistix 3200/16 in peformance?

So i can use the difference between that and 3600/cl16 kits as a reference for how much fps i would gain OCing my own RAM (i have crucial RAM)

[u/Old_Miner_Jack]

picking the right memory kit on paper is one thing, spending hours tweaking timings will always make a difference in the end.

The review is interesting, but there are so many parameters involved in memory settings that CL and frequency dont tell all the story. Subtimings are so impactfull on the final results that some loose or bad subtimings can alter or reverse the gain from lower CL or higher frequency. That's why some of GN results could look somehow counter-intuitive. Manual tweaking is the only way to get all the juice from any memory kit.

I know this isn't the right thread, but can anyone point ne to a good, detailed, ryzen overclocking tutorial? I must have tried at least 5,6 times overclocking my ram and each time I would end up having to short 2 pins on the motherboard because it wouldn't boot properly and reset all bios settings. I don't know how to set the timings properly and what voltage to increase aside from DRam voltage. I might be asking for a lot here but it would be of great help if anyone with overclocking experience would guide me directly.
