Identify issues causing random app crashes on your PC.
Identify issues causing random app crashes on your PC.
Your CPU is severely affected (specifically an Intel 14th gen model). The best way to resolve this is by slowing down your P cores. For me, lowering the 6GHz cores to 5.7GHz is sufficient. You might need even lower speeds—possibly all cores at 5.6GHz. There’s no advantage in going through a return merchandise authorization. I already had my first 14900K covered under warranty after it became unstable, and my latest unit also failed after six months. The new chip only uses the updated microcode, but it doesn’t fix the problems. I can still RMA it now, but the next one will likely fail too. If you reduce those two P cores from turbo to 5.7–5.6GHz, the crashes should stop—this points to a hardware fault. That’s the only real solution left. I’ve tried hundreds of troubleshooting steps by mid-2024, and this is the only path forward.
Consider trying a lower clock speed for all P-cores. It might be a better way to handle the problems without risking too much performance loss.
I tested both CPUs with only a slight reduction in clock speed, specifically lowering the two 6GHz cores, and they ran smoothly without any crashes. I’m unsure if performance will drop further, so if issues arise again I’ll know to try even lower speeds before investigating other factors. If reducing all P cores to around 5.5-5.4GHz still causes problems, it’s likely another component is involved. I haven’t tried running them below 5.7GHz yet—possibly not long ago—and still experienced crashes, suggesting the CPU design for 13th and 14th generations struggles above that frequency.
It's good to hear it's improved! You're usually able to complete the test runs in about 4-6 minutes, but now you've managed a 15-minute session. That suggests stability has been achieved.
No certainty about whether the slowdown is limited to exceeding 5.7GHz or if it gradually reduces CPU performance over time. I maintain 5.7GHz because the system remains functional at that speed, even though it might eventually drop further. I plan to return for an RMA once noticeable performance drops occur. For testing, I relied on a simple overnight test—watching if the PC restarted upon waking up. If it stayed running without any restarts, it’s likely fully stable. Avoid relying on minor updates like Windows patches that could mislead you about stability.
It’s on my agenda to let it rest for a while. If 5.7GHz is fine for you, trying 5.5 could give me extra reassurance. By the way, do you have XMP turned on on your device?
I use AMD EXPO certified memory, two 32-bit DDR5-6000 CL30 modules, not stable for overclocking but works well as is. I previously owned a pair of 16-bit DDR5-6000 CL30 (identical speed and timing, just smaller) Intel XMP RAM, which didn’t improve CPU performance.
