Question on Ram thinking of going with the Vengeance RGB Pro 3600 CL18 2x16gb or Dominator Platinum RGB 3600 2x16gb or Vengeance RGB Pro 3600 2x32gb CL18. All are Samsung C-die right? I’ll max my board out at some point with whatever one of the three I go with. Will I see a performance drop from my 4x8gb Balllistix 3000mhz micron CL15 over these? like 1-5 FPS and the whole 10 to 8.xxxx ms?

Doing the whole buy a bunch of ram and use this pc for the next 8-10 years with 2-3 GPU upgrades during that time. The whole so much ram any game that launches with resource issues/memory leaks I will muscle though it like I have the last eight years on my old pc. Would rather not lose 1-5 FPS right now if that is the case. On intel so know there is not a huge advantage in going with faster ram until you go to the 4000-5000mhz mark.

mhz and CL are linked.  As mhz increases CL decreases.  You want the highest mhz and lowest CL you can afford.

This isn't true. RAM timings are somewhat independent of its clock. Typically, faster clocks will mean slower timings. There are websites that can tell you the real-time speed of your RAM based on its clocks and its timings. Higher clocks and lower timings are better. Thus, 3600 cl16 is better than 3600 cl18, but honestly not in such a way that's worth the extra money.

Agreed. The performance difference you will see is not equivalent to the increase in price

higher frequency and lower latency is the desired target...you can find a formula that showing the results on your ram

The problem with RAM is that for the CPU ram is insane slow compared to the L1-L3 registers. That is the reason why high performace computing always happens inside the main registers. This means that RAM speed is not so important you will always hit the sweet spot with the midrange RAM. So I agree to s response "The performance difference you will see is not equivalent to the increase in price".

Your best memory also depends on your CPU. For example, when it comes to the ryzen 5000 series, 3600MHz seems to be the sweet spot. After that, upgrades just do basically nothing in terms of performace. There is testing out there for almost all combinations of CPUs and RAM you can imagine. Just gotta go digging.

3600mhz is what you want for the ryzen 5000 series.

will 3200 work fine too

don't even bother with high end RAM. when search for ram in 2021, just get whatever 3200-3600 is on sale. unlike CPU or GPU, RAM is something that you are very unlikely to notice. it gives you the least performance gain per value.
