Long story short: Been suffering random crashes and reboots since building my system in April. Thoroughly tested and found out it’s due to the strain of 96GB dual rank ram on the IMC.
– CPU: 7950x
– GPU: 3090,
– RAM: 96GB dual rank 6400 32-39-39-84
– motherboard: MSI Carbon x807e
I’ve been tweaking a ton over these last months and still experienced crashes, almost always after sleep or cold boot. I think this set up may get the best performance with stability after I’ve been trying to learn more but I want some feedback on it.
Is core clocks supposed to be 4.5-5.5 at idle? This was about five mins after logging in and just sitting on desktop. I know background processes were probably running but I want to know if this seems too high.
Any temp readings suggesting uneven thermal paste application?
I would also appreciate any feedback on the voltages and timings I set and open to any suggestions
Btw in my BIOS some of these settings repeated across three different areas (Overclocking, AMD CBS, and AMD Overclocking. I changed them only under Overclocking because i was worried changing all would cause conflicts
