Hmm. So i got my new 5900x and the problems persist. My write speeds are always messed up. Across all caches the read/ write/ copy ALWAYS vary across l2 and l3. For the l1 cache it very often. From what i understand a variation in over 20 gb/s shows some sort of instability. This problem is even on stock. I cannot figure it out i have replaced everything. Last thing i have is i replaced my PSU with the same PSU model. Maybe 5900x doesn't play nicely with corsair rm850x? But then again my laptop is starting to come out of sync too. (4800h). Could i have like bad electricity that is frying my hardware?
Did you already RMA your 5900X and this is a new CPU? Got any screenshots of this?
I have to admit I don't care about cache results much. There's too much that can impact that - AIDA being AIDA, unstable CPU OC, unstable RAM OC, unstable IF, insufficient VSOC or minor voltages, bad windows config (too corrupted/damaged, or too many background programs), bad CPU, bad board...... As long as it's roughly in the right ballpark I haven't paid too much attention.
After my experience, I would probably look towards the board and the RAM. Did you say you were on DJR? If you're able to I'd just pick up a B-die kit from Amazon (30 day returns) and see if anything changes.
20GB/s seems wayyyyy too stringent a requirement for any L1/L2/L3. If you're running at stock then even the boost algorithm alone will naturally account for run-to-run variances bigger than that.....100GB/s is where I'd call it instability, and 200GB/s a bug.
