Will I need to overclock RAM again? (reddthat.com)

I'm saving up to get a 5700X3D around Christmas, upgrading from a 5600G, but I want to make sure I prepare properly before I do the swap.

The RAM I bought couldn't match the C18 @ 4000 M/Ts advertised and still remain stable, but I managed to manually overclock to C16 @ 3666. Should I drop to JDEC specs before I upgrade, or is it a non-issue?

So AMD (AM4) is not good for running over 3800mts. 3600 is the "sweet spot" and may actually get more performance than 3666

MaxxMem is a good free program to test the performance and use Occt to test memory stability

*With the exception of APUs. I believe 3800+ (even 4000) is fairly achievable on Cezanne

3666 produces a good latency with C16, and I was able to boost Infinity Fabric up past the default to 1967 (it's complicated, but it's something you can do under certain circumstances). I had to get the highest speeds I could manage, because the original build was a stopgap before GPU prices dropped.

Unless I can get the RAM to work at C14 @ 3600, it won't be much of an improvement over what I have currently.

My stability suite is a mix of OCCT, TM5, and Prime95. Takes about 3-4hrs to get through all of them. 😅
