I think I will do that. Presumably the ram xmp settings should be the same for both Ryzen 7 chips.
Sythe fuma rev.b cooler comes tomorrow, so I'll open it then. I can test 3 processors : 1600af (aka 2600), 5700x and x3D.
Even picked out the games to test, a mix of old and new to see how the 3d cache reacts.
Witcher 3, metro Exodus, kingdom come deliverance (since I know it really is affected by cache) and crysis warhead.
Heck I'll throw Spyro ignited in there since I'm currently playing it (runs at 120fps 1080p on 1600af, could probably hit 1440p but my tv can't do 1440p 120)
Normally I would test at 1080p but since I "only" have a rtx 3060, I am going to test at 720p to see how the x3D will scale with the new 4xxx series and onward.
