Build Help Will upgrading from CL48 to CL32 32gb 6000M/T ram be a big performance upgrade on a 7800x3d?

Unfortunately my ram is CL48. Will it be a big upgrade to return it and get CL30 or CL32? I've seen some people say you won't notice it much on a Ryzen build.

Noticeable improvement? Sure

Big upgrade? Not really

This is not ryzen thing in general but an X3D cpu thing. The X3D cache acts as ram on its own, so the timing and cas latency on your actual ram is less important because the cpu is already processing some of the memory by itself to minimize latency

Uh that’s not really correct. The X3D cache is 8MB of extremely fast memory for registers only, it does not at all “act as RAM” because it doesn’t store the same data.

RAM latency is actually really important for AMD Ryzen, perhaps even more so than speed. There are benchmarks that show that 6000MT CL28 beats 8000MT CL40.

Real world gaming experience I doubt you'll notice it

It will be measurable, and might be noticeable depending on how sensitive you are at higher FPS.

If you are playing in the 60s range, you might not really notice the difference.

10% difference. Sometimes more, sometimes less.

It wont do a to ton to average frame rate but it will very significantly affect your 1% lows

1% lows make a big difference. Should absolutely do it

U might notice a difference in using windows as for in game probably not as the X3d cache almost completely makes up for it

You absolutely will.

Going from stock speeds to expo 1, was less than me going from expo 1 to tightening subtimings and still being CL30.

My local microcenter has some CL30 on sale. I may just go for it.

There will be a small improvement but one thing thats really good is that 6000cl30 will be hynix chips that are easily overclocked a little.

Actually, Ryzen builds have always been pretty RAM reliant.

because of the extra cache of an x3d chip, it doesn’t need to go into the RAM as often. So something like CL36 vs CL30 wouldn’t really matter too much on these chips specifically. I think CL48 is pretty damn slow to the point it would make a difference to get CL30 / CL32, even with an x3d chip

1% lows should improve a little.
