I own four RAM sticks from Corsair. They aren't listed in the motherboard's QVL, but my motherboard still works with 3200MHz speeds without any issues. My PC has been freezing and stuttering recently—could that be related to the RAM? Is the problem with the RAM itself or is my motherboard just too slow for it? I’m hoping you can help me figure this out, especially since I have an i9 9900k Z390 AORUS Master Corsair Vengeance RGB 32GB. The latency might be around 16ms. Thanks!
here’s what else you might need to know about your setup. since amd offers strong performance around 3600 mhz, it seems like you’re using an intel processor. on your 9th gen i9900k, the issue was likely due to excessive cooling pressure—tightening the screws slightly improved stability. you mentioned having four sticks and enabling xmp, but that’s not a direct fix for this problem. there are many possible solutions depending on your specific hardware and configuration.
i9 9900K Z390 AORUS Master Corsair Vengeance RGB 32GB, 3200MHz, latency likely around 16ms. That seems reasonable.
This setup has an older system, so results are uncertain. We don't know if the RAM or motherboard is the problem. Try running the machine with only two sticks of RAM and let us see how it performs. I use a 4x8GB G configuration and have set it up successfully on my Z370 without any issues.
Or consider alternative RAM options. My main concern is the sudden instability. When was the last time you updated Windows? It could be due to a downloaded file or extra apps causing problems. There might also be a software-related issue.
