"It's only wednesday and it's been a long week" I felt that

[@tmorris93]

9:40 I own both a 3950X system and a 3990X system. In Ryzen Master, you can set clocks by core, by CCX, by CCD, or all core, as well as turn entire CCDs off. The issue (in my admittedly somewhat limited testing) is that you cannot set the voltage per CCD-at least, not through Ryzen Master. So all that fancy undervolting we might be able to do (for example, my 3990X is stable with up to a .075V offset and the clocks otherwise left to auto, and I can run my 3950X at 1.10625 and still hit 4150MHz all-core) is wasted when we have to give the okay to 1.3V+ just so a single CCD can hit that higher clock. It would be really nice if Ryzen Master let us set per-core or per-CCD voltage, that way we could set our programs' affinities so we have a low heat, decent clock on most of the CPU, but then have our 4-8 cores set up to be a little higher clocked for gaming. More granularity is always better, if the user takes the time to understand what it is they might be tweaking of course! As far as the ideal RAM clock speed, Steve made a really detailed video a few weeks or months back (what even is time?) that explained how the uclock, mclock, and fclock like to be in ratios with each other, and pushing fclock past 1800 whacks out the uclock to be 2:1 instead of 1:1 (basically cuts its clock in half), which robs you of...I want to say 9ns. But of course depending on your kit, if you just push even harder on your mclock and tighten the timings even more, you can still overcome this drawback. For normal people who want to spend their time using their computer instead of tweaking it (both of which endeavors are valid and good fun), 3200C14 or 3600C16 are some pretty attainable sweet spots currently.

[@nightstorm10]

Just to clarify the bit about the FCLK (Infinity Fabric clock) at 8:26 and 12:04 - you do NOT want to run FCLK at half the speed of the memory, you want to run it at the same speed as the memory (1:1 ratio). Keep in mind the effective clock speed of DDR memory will always be double the memory clock speed shown in BIOS because it is double data rate. Just bringing this up so people won't go and set their FCLK at 1:2 by accident for 3600 speed or lower. So, like Jay says at 11:53, this is why the general consensus is that 3600 speed memory is the sweet spot for Ryzen. Most (if not all) Ryzen CPUs will do 1800 MHz FCLK for a 1:1 ratio with DDR4-3600 memory. As to 14:29 - you absolutely can run 4200 memory if you want on Ryzen without any additional effort (assuming XMP/DOCP for your memory kit works at that speed on your motherboard without additional tweaking) but you would probably be looking at setting FCLK to 1050 MHz in 1:2 ratio and lose some or all of the performance difference. And it costs a lot more, so probably not worth it.

[@ppmguire]

Best case scenario after fiddling with Ryzen for the first time was lock my cores to 4.3 and set faster RAM to 3600 with tighter timings and run 1:1 with IF. PBO was always inconsistent even under water for my 3700x. I find it comparable to my 7800x locked at 4.8GHz in gaming while also having 2 extra cores.

[@Noksus]

Fabric clock isn't half of memory speed when it's half of *reported* RAM frequency. DDR means Double Data Rate, which means RAM talks twice per clock. That is shown as double actual frequency. Fabric clock is exactly RAM freq when it's "half", probably also why it gives the best performance because they are in sync.

I wouldn't say 3600 is a 'sweet spot' at all. It is for Ryzen 3000 if you don't manually OC your FCLK cuz it maxes out at 1800mhz by default. That said 3600 cl16 is a great kit of memory for out of the box XMP/DOCP. There's a lot of 3600 CL 18 kits out there which is technically slower than 3200 CL15

[@amcdonald7479]

[@webcodr]

Since the Infinity Fabric clock is directly related to the latencies of inter-ccx/inter-ccd communications, Zen 3 will be large step in reducing latencies. With Zen, Zen+ and Zen 2 each CCD/chiplet has to two CCXes with 4 cores and 16 MB L3 cache each. So, if Core 1 on CCX 0 wants to talk to Core 2 on CCD 1 or access the L3 cache on a different CCX, it needs to go the way around and use Infinity Fabric. The almost doubles the latency compared to an access to a core on the same CCX. Zen 3 will introduce a new CCX design with eight cores and 32 MB L3 cache. One CCD will only have one CCX. No more way around when cores on the same CCDs are communicating. This will help especially on the mainstream CPUs with only one CCD (4, 6 and 8 cores). Within a CCX AMD has a lower cache latency than Intel. Inter-CCX latency is currently about 70 ns, it depends on the RAM/IF clocks and the timings. With a good Ryzen 3000 that can maintain 1.900 MT/s IF clock and really sharp timings, it's possible to reduce the latencies to lower 60 ns values. This greatly improves the performance in certain games and engines (f.e. Far Cry 5), that favor clock speeds and a low cache latency. With Zen 3 those 70-something ns will drop to about 40 - 45 ns on the same CCX. Together with improved clock speeds thanks to TSMC's N7P process and further IPC provements, AMD could finally beat Intel in those games.

I don't know about you but ordering multiples of twin packet sticks (ie x2 packs of two sticks/pkt for 16GB DDR4 @3600MHz) saves a coupla hundred, compared to 4-pack 'matched' ram. Its much like Crossfire and SLI to me. The bet I make is to stack twin stick packs in the A1 B1 +A2 B2 dimm slot order so the electronic abstraction sees each matched ram pair in their own channel (if I have that right). **Can't wait to finish my build: now 64GB of 3600MHz ddr4 richer, just arrived. G.Skill Ripjaws V Black, in a Black Corsair Crystal 280X mATX case with its glass top pane sitting on stacked nylon washers and the grommets upside down for extra standoff height, main glass side panel grommets reversed to set panel flush against case, front panel dust filter removed.

Almost everything going on inside my case is black, except the brushed aluminium heatsinks of the Asrock X570M Pro4 mobo, and its white printed stuff, and the Ryzen 9 IHS. Not a fan of pretty lights. I might custom build a puppet theatre stage curtain-esque drape to the glass side panel .. I'll think it over.

[@MatWilson2612]

IPC multiplied by clock speed is what gives gaming performance. Example. 5.2GHz FX8350 gets destroyed by a 8700k @ 3.6Ghz (MCE off). You cannot use clock speed to measure performance unless it's the same line of CPU. E.G 9700k @ 5.1ghz vs 9700 @ 3.8ghz, you can get an understanding of it for say a 8700k vs a 9700k as it's the same architecture but still a different configuration.

[@tech4u2022]

You can tune the Ryzen cpu's any which way you want with Ryzen master. If you turn OFF precision boost and Cool&Quiet (in the BIOS) you can use Ryzen master to maximize all overclock components to the max. without risking damage. I currently got a Ryzen 5 3600 running at 4.3 Ghz all cores with overclocked RAM (2666 to 3200 Mhz) just buy changing the core clocks and FCLK within Ryzen master. These settings resulted in the best scores ever reached with this configuration in benchmarking tests (novabench,userbenchmark, etc..) It took a lot of testing but it seems to me there are 2 realistic options for Ryzen owners : 1. keep it at stock settings and use ODCP/XMP (which i actually recommend for the majority) 2. find the sweetspot and keep it there (or at least find the highest stable overclock) HINT : if your motherboard can exceed the limits of your cpu then use ryzen master so you don't have to clear the CMOS all the time after a lock up ...

There is a reason that AMD specify Max supported memory speed of 3200 with Zen2. (F-CLOCK is to be at max 1600 FOR 100% STABILITY) Rest is OC, and therefore stability varies. And deminishing returns in performance. Use as good memory you Want to pay for. Set it to 3200 MHz. Instead of higher clocks, lower timings as much as possible at the XMP rated 1.35V (you can generally set higher than rated voltage for even lower timings - at own risk). Check Actually Hardcore Overclocking for more info om RAM / Voltage scaling.

Gigahertz does not reign Supreme. The combination of gigahertz and instructions per clock does. You can overclock a bulldozer to 5ghz if you want, and you'll still be slower than a 3ghz Ryzen 3.

[@leviathanpriim3951]

tl:dr 10:42

[@TrueThanny]

08:26 No, it's when FCLK exactly matches the memory clock. You're just forgetting that DDR memory is reported in MT/sec, not MHz, because there are two transfers per clock cycle. DDR4-3866 has a clock speed of 1933MHz.

[@b747xx]

Yes, you can set coef multiplicator per CCX. Mine is 44, 43 ,42 ,42 (3950X)

[@ReivecS]

I definitely want to see a timing video. Maybe take 3600Mhz since that was your recommendation and test various timings on that. I have long held the view that getting a lower timing on memory was better than squeezing out a few hundred Mhz on the clock speed. I would like to see how that assumption holds up since that ultimately comes from dated information.

[@timsteiniger2011]

I bought 2133mhz Hyperx Fury black for my ryzen 1400 3 years ago. Today i started playing around a little bit and at first got it to 3200mhz but got a blue screen after 1 hour. Now at 3066mhz it work flawless.

[@timsteiniger2011]

I have someting in the 2-3 percent performance increase in sintetic tests. But i notice battlefield games with less fps drops.

[@n1kobg]

Jay, you can make a chiplet OC and that way set the individual cores to different speeds. Also play with NUMA modes.

[@praetorxyn]

Buildzoid did testing on this last year I think. Best I can remember, the sweet spot was 3600 MHz / 3766 MHz / 3800 MHz (can't recall which) with the IF overclocked to 1900 MHz. Since I wanted dual-channel and 32 GB, and the daisy chain controller, I got the Trident Z Neo 2x16 GB 3600 MHz CL16 kit, and I haven't had issues. But then I haven't messed with manual memory timings or the IF, I've just rolled the XMP.

[@charlesharris9784]

This is why I have been so damn confus d with my ryzen 9 and best suggested ram . Going nuts

[@TheCantarelli69]

My 2 x 8Gb 3600mhz cl 16 RGB by crucial for 110$ is a big leap from the cheap 2 x 4Gb 2666mhz or less. People all time asking for B die timings, that is time spended for "OVERCLOCKERS" . To regular users is relevant

[@gusgo187]

Thanks Jay. Took my 3700x system from 4947 to 5010 in cinebench R20.

[@hendrikschepkens6455]

I game at 1440p ultra wide with a 6700k @4.5ghz I dont feel the need to upgrade realty soon Skylake was a huge boost towards everything before.

[@seanshah1651]

i tested those high end mainboard like x570 godlike can OC right from bios . The ryzen 4000 will be running even faster for Fclock too which mean can use faster memory .

[@albertnavara7700]

About the single core clock, I think that you can do per thread overclocking in Ryzen Master so you won't lose that single core performance by locking it 4.2 GHz all-core.

[@aryannarose]

Ryzen 9 5900 G Skill Trident Z Neo cl14 3800mhz 4x8gb tight and stable increased my FPS in games by 20-30 fps.

[@JMayer-rg5nu]

you can adjust individual core clocks in Ryzen Master.

[@GlobalGarageAus]

Not your best work... Timings do matter a lot. For example 3200 at CL14 = 8.75ns latency. 3600 at CL17 is actually slower at 9.4ns even though the packet advertising says otherwise.

[@mattking4483]

Can get my 3800X to 4.5 GHz all-core at 1.325 volts for gaming, 1.375 for AVX instructions. Maybe try something you can clock higher rather than going for the 3950X and gimping it at 4.2? Then again, 3800XT can supposedly get to 4.7, possibly all-core. Also, Ryzen Master (and the B550 boards in BIOS) allow for per CCX 'overclocking'.

[@aleksandergjengst782]

The weird thing is..after overclocking my ram from 3200 to 3666 with the clock values from ram calculator,it didnt realy show in cinebench or other benchmark software..BUT !!! IN WARZONE2 it made a huge impact!! 20-30 fps..no cap🔥🔥 im extatic😅

[@georgekennedy9299]

I dabbled with this myself, I got a 3800 cl14 kit, Set it to DOCP, it runs good, but then raised the fabric clock 1866, and it's pretty impressive, I couldn't get fclk to 1900, it posts, but freezes at windows splash screen, tried turning ram down to 1866 to match and I actually lost 60 points in cinebench, so I've left them un-coupled for now

[@quipalco]

I don't know if it's just my board or all 450 boards, but I can't get mine to go passed 3200 mhz for RAM. It is GSKILL Ripjaws V 3600 mhz ram. I have an ASRock B450M pro4 MB. In the UEFI I can enable the XMP and turn it to 3600 but it turns the voltage to 1.35 and it's red. It let me save and exit, but it kept changing it back to Auto and 2133 mhz, and also being unstable when I would try to reboot after enabling XMP. But, If I enable XMP and turn it to 3200 with 1.3v, it actually stays and runs smooth and seems to run better than the 2133. This is my first build. I think the board can only do 3200 mhz for the RAM unless I'm just a complete noob. Using Ryzen 5 3600.

[@PERSPECKTiVE]

"3.5 is SLOW nowadays!" ....Man reminds me of when the AMD Athlon 860k was out back in 2015. People raved about its 3.7ghz clock and $100 price tag (or $80 sale price).

[@andibiront2316]

About all RAM setting itself to 2133MT/s. Not true. DDR4, as with any other standard, will configure itself to any JEDEC profile common to all DIMMs. Maximum JEDEC standard for DDR4 right now is 3200MT/s. That's why AMD Zen 2 CPUs provide official support up to 3200MT/s DDR4, they can't go above the standard. Which I think uses CAS 22. You usually see 2133MT/s or 2400MT/s on XMP enabled memory because they are using 2133 or 2400MT/s memory ICs binned and configured outside of spec. Another thing. Timming is crucial on Zen 2 CPUs, which have the IMC off die. That means you have to jump to a different chip, crossing the Infinity Fabric, which adds latency. Also, JEDEC timmings tend to mantain the access latency across the range, and only provide more bandwidth. Not using real timmings but supose a DDR4-2133 DIMM with CAS 14, it will have the same access latency when overclocked to DDR4-4266 CAS 28 (let's say all other timmings also doubled). It's not that hard for the memory IC when this happens...

[@paetonlaturner759]

You really should have tested a 3600 cl16 bdie kit and tightened the timings down for the best results

[@jessehughes88]

I actually was just looking for a timing video because I thought it would be nice to tighten up my timings on these trident z neos I have.

[@wow1371]

I have learned a lot from your channal Jayz. You are really good.

[@old_newbie9498]

Isn't there a ram divider that kicks in after certain ram speeds that essentially reset memory performance? You need to test 3200, ~3400, 3600, ~3700, ram speeds as well, and check when the dividers kick in. There are certain ram speeds that will peak performance at a particular divider, but then drop after a new divider kicks in (ie. 3600 is peak of one divider, but a new divider kicks in at 3700 and performance drops down a bit).

[@Eskoxo]

got myself gskill 16gb x2 3600 cl 16 kit for 150 to use in my 9600k build while waiting for that ryzen 4000 upgrade.

[@Meglenger]

I bought a 1700 way back that wouldn't let me even touch my ram clocks. To this day they are stuck at 1866 mhz. Gonna be upgrading here soon tho.

[@haydenvaughn00]

Alright...so what about a 16GB kit of DDR4 3600 CL14. More specifically talking about the Teamgroup T-Force Xtreem ARGB kit. Would the faster speed and really low latency be a huge/noticeable boost for Zen 2?

[@korbensc7218]

Thanks! This video was actually helpful. Don't get it wrong, lot of your videos are helpful/informative (or, at least, entertaining ;)), but I am currently planning a new AMD build and was not sure about reusing my old RAM.

[@israellewis5484]

I'm pretty sure you can set individual clocks for cores in Ryzen Master
