Constant crashes

[BrokenBlack]

Hello everyone,
my System keeps crashing very often, especially when the CPU needs to do lots of heavy lifting, like in Unreal Engine 5. Also while playing games I often experience these issues.

Resulting in Software crashing (when lucky), or the whole PC rebooting or resulting in blue screens.

I was able to reduce crashes by disabling XMP, and downgrading from 32GB RAM to 16GB RAM (removed two sticks).

My Specs:

I5-13400F

B760M Pro RS/D4 WiFi

MSI RTX 4070

(now) 16GB RAM @2666MT/s (could be 3600MT/s)

PSU: CX750F RGB

Windows 11 Home

Is there anyone who has had any experience with these issues?

exact same issue as mine.. crashes are tied to memory stability.. Disabling XMP and pulling sticks back to 16GB improving things kinda confirms that...

...but I tried to update my BIOS as memory compatibility fixes often come through updates

you can also run MemTest86 on each stick. If one fails, you found the culprit. Mixing two separate kits (even same brand/model) can cause instability. Always buy a 2x16 kit instead of 2x8 + 2x8 later

Instead of XMP, manually set frequency/timings/voltage in BIOS. Start with 3000–3200 MT/s and work up. That CX750F is decent, but try swapping or testing with another PSU if you suspect power instability. Use Prime95 or OCCT. If it BSODs even with safe RAM settings, it could be CPU or VRM related...

reset RAM, GPU, cables. Simple but sometimes fixes flaky connections. 

In your case, I’d start with BIOS update + MemTest + only using a proper 2-stick kit. That fixes 80% of these exact issues...
