Hi all,
I've been trying to tweak my memory but I feel like I've hit a wall. I'm running a 9950X3D on MSI MPG X870E CARBON WIFI, with 2 kits of 2×48 Corsair CMK96GX5M2B6000Z30. Current timings are in the screenshot, currently tested with 3hrs of Y-cruncher VT3 and 1hr of OCCT. Some insights into what I've encountered so far:
– out of the box the memory boots with the 6000cl30 EXPO profile, although its unstable in Y-cruncher (crashes almost instantly)
– any voltage adjustments while the EXPO profile is loaded results in failed memory training (Ab on motherboards debug LED)
– at first I ran the memory at 5600 38-38-38-96, but was disappointed with the performance, which resulted in the last 2 days of trial and error
– for now I've tested the EXPO profile timings bumped down to 5800 with tREFI set to 50000, temperatures are below 55C and it passed 3hrs of VT3 (will test further with GPU heat accounted for, maybe get some kind of cooling solution?)
– 9950X3D curve optimizer is set to -10 on both CCDs, lower values didn't bring any performance improvements, ccd0 -25 ccd1 -20 +200mhz would crash on VT3
– I get ~43500 cinebench r23 with the current setup
Usage is mixed, 3d visualization (Blender, 3ds max, UE5) as well as some gaming – was particularly disappointed with BF6 beta performance, I have a 5090 FE and was below 160fps most of the time at 1440p
I feel like 6000 is somehow possible with some tweaks, I just need some tips on the correct approach for this. I already researched previous threads (thanks u/Scarabesque for the very helpful post) but figured I'd ask here. Maybe 5800 would work better with some tweaks to the CPU – but at the same time 6000 is said to be the sweet spot for AMD?
