True, but in my country, due to occupation, there are few options to choose from. So I have to choose the cl36 ones I came here to chick if the difference is huge!
Primary timings in DDR5 are not nearly as important as secondary timings. I’ve seen kits with tuned secondary timings perform 10-20% better in AIDA than standard XMP/EXPO profiles. It also doesn’t affect FPS so much as it improves stutters. You’ll usually see higher 0.1% lows with a low latency, tuned kit, which for titles sensitive to memory such as MSFS can make a noticeable difference.
Wait: WHY does the CL36 Ram have (in many games) better 1%-Low (higher FPS) than the CL30 Ram (for example Cyberpunk)??? Can somebody please explain. Thx!
It's because the CL30 ram has lousy sub timings 30-38-38-96 vs 36-36-36-96. Them 38 sub timings is killing the performance as it delays the clock cycles of the primary, so having a sub timing of 38 = primary timing is effectively also 38. If it was 30-30-30-76 then it would be faster.
6000mhz cl30/32 (36 less comparable but still fine) is ideally the best for its price, but i would consider 6400mhz CL32 the ideal speed for ddr5 speed for a gaming ramkit. Compared to a more comparable lower-end speed like 6000mhz CL30 the 6400mhz cl32 raw preformance wise is hardly different, but it can handle marginally better sustained frametime making the average fps more reflective of the actual framerate relative to the frametime without the microstutters and ect, both of these benefits wear off fast the more its utilized but under high fps i would see this as more ideal preformance wise for what you can buy those ramkits for 2x32 if you have the extra money to spare, although ur gonna have to have fun getting it to work properly with the amd ryzen 7 7800x3d it can be done but if you want a straight out of the box easy installation 6000mhz cl32/30 would be the most benefical for its price and better optimization that doesn't need to be messed with unlike with higher speeds, dpeends on how much money you have but i would definitely use slightly higher bandwidth ram like 6400mhz with a slightly higher cl rating like cl32 at the minimum.
Cas Latency in gaming is dependent on the title. Some feed on bandwidth and others on Latency. Lower latency in most games doesn't boost the fps but it keeps the 1% lows more stable equating to less dips and stutters. A good example is hogwarts being played on a 4060, it will still be a horrible experience but for bench purposes you will see less dips overall. Also running tests at 4K on an entry level to mid tier gpu may yeild some telling results due to the gpu using near max VRAM it then starts to use the dimms to speed up cycling data to and from the cpu while also releaving its load to stay operating without crashing in this case lower latency will matter more. Testing on a 4090 will show lowest differences in latency due to its 21GB/s memory speed @1313mhz default memory clock over the 384bit bus gives us a overall memory bandwidth of 1008GB/s. At 1080p this 6 core ryzen is the bottleneck so the dimms dont have much to do except send info back to the gpu. Which DDR5 has more cycles. 3D V-Cache has lower bandwidth but low latency as its directly on the CCD but yet they seem to be the only cpus that wont bottleneck a 4090 (not including i9 13 & 14). I understand the logic behind these 1080p tests as the cpu relies on the Ram but CL wont matter as much because of how fast DDR5 cycles information back to the gpu that isnt stressed at all with PCIE 4 x16 slots rates to 64GB/s I believe the gpu is feeding directly to the cpu and recieving data from the Dimms.
I don't think this guy tested 2 types of ram. Videos like this will usually take one type of ram and infer the other type. I have 2 types of DDR5 6000mhz CL36 and CL30, I almost can't tell them apart.
1 fps difference in most cases. Get the cl36 or higher if its a lot cheaper. I personally will get cl36-38-38 2x32GB for 200$ instead of 2x16 cl30 for 120
Sounds about right. FPS is per second and not per cycle. And when talking cycles cl30 is indeed faster. But translate this back to seconds and well... not much left of the obvious difference discussed in nanoseconds 😁

Hello you are using AMD Ryzen 5 7500F in this test. 7500F Max Memory Speed Cpu spec page DDR5-5200mhz, so 6000mhz rams working but giving realy better performance in games ?
6000 (MT, not MHz) is still considered overclocking. 5200MT is max. recommended for all Zen 4 CPU, it’s basically a disclaimer that everything beyond that is at your own peril. Actual max. speed can be much higher. For instance, I’ve got a 8700G - also Zen 4/5200MT - that happily runs DDR5-8000.
If you game at 4k ultra, there is NO difference. Likewise if there is NO difference between the Ryzen 5800X3d and the Ryzen 7950X3D.

At which case, yeah. Deffo get the 3d version of AMD, if that's your bag.
@@TaidaDave do the math or just check what the Ram Latency (ns) is. Example 6000mt/s CL38 is 12.6ns I believe and 6600mt/s CL40 is 12.12ns but I would say the sweet spot is 6000 CL30 for me and my 7800x3d 7900xt build.
Games do not require more than 32GB of RAM. In fact, the majority of games do not require more than 16GB to perform optimally. 32GB of RAM with a high frequency and low timings is the ideal configuration for gaming. I can say with great confidence that 32GB of DDR5 6000 MT/s CL30 will outperform 64GB DDR5 6000 MT/s CL40, albeit by a small margin. Basically, just get whatever you can afford.
It always depends on what you consider good enough. You may not get the full expected performance out of your processor but you will still have at least 80-90% of the performance (depends on game to game basis). If youre the type that likes to upgrade, then I would recommend getting a CL30 kit as you likely wouldn't need/want to upgrade until DDR6. But if you build your PC once then never touch it again until your next build then compromising would save you some money overall. Alternatively, you could just buy a CL36 kit and manually tune your RAM to CL30 but this is a bit of a gamble because the scaling of your RAM in overclocking is never a guarantee.
