Can you show AMD Ryzen RAM OC in terms of hitting the limits of speed and latency? The new Zen 4 bios supports very high RAM speeds now ... up to 7200 MHZ depending on silicone lottery IMC.

Ryzen DDR5 8000 on a 7900X [youtube=mEnOu57x3wE] It looks like a dual ccd is needed to take advantage of higher memory speeds, a single ccd has other bottlenecks then the memory speed, leading to very little difference. 8000 speeds are barely faster then 6200 1:1 because of the divider used. My 7800X3D scales like crap because of the single CCD and 3D cache makes memory less used anyway.

I've learned something like this just yesterday during my research as well. Searching for fitting RAM kits for the 7800X3D I want to get for my upcoming build.

for my upcoming build.

Hmm, I cannot be sure if this is fake news and when it comes to computing an industrial standard. But yeah, if its a legit claim then I expect the new build to have so much style that it gives you whip lash. Anyway, looking forward to seeing what ever form it takes. 🙂 The thing with ram is be it DDR or GDDR is that its just never fast enough. In fact it so slow that we now have cache on our CPU's and GPU's In L1,2,3 and 4 and these caches are getting real big in some cases, like 1GB big. Obviously this is all to compensate for how slow ram is. If ram was fast enough to not need to rely on L cache, then how fast would it be. DDR? and GDDR? 😛
