Niedrige Spannung von 12600k führt zu Absturz beim Start
Hello. I started exploring undervolting and overclocking my 12600k, which is now paired with a 7900xt. I increased the clock speed and it was okay except for the temperatures, so I moved on to undervolting. The problem is that even with a 0.05V reduction, I experience crashes at the Windows login screen. It works briefly but then freezes. This seems to be the point where a crash occurs. My current settings are 4.6ghz, 0.035 UV, with temperatures in the mid to high 80s during the furmark CPU burner stress test. I’d like to raise the clock speed a bit, but temperatures are the main concern. Is there anything I can do? Does this suggest I’m hitting the UV limit and overclocking too much? Any guidance would be appreciated. Thanks.
If it crashes right away on startup, it suggests the hardware isn’t reliable. Did you run stress tests after overclocking and lowering the voltage? I think the system was already struggling but didn’t show issues under normal use. The only fix is to avoid pushing temperatures too high and overclocking excessively—otherwise you’re just wasting your chances.
I mainly rely on occt for CPU testing. It handles heavy tasks, though it's not as powerful as ycruncher and realbench+r23.
Thanks in advance. It doesn’t seem like I’m missing anything. I’ll check if I can adjust it, but it’s already what it is. I mainly play VR, so it’s usually GPU dependent. Appreciate the feedback.
Avoid running r23 as a stress test, okay. Large mixed varied is better, prime is good.
Many 12th Gen CPUs react strongly to adjustments in cache voltage or speed during undervolting. Cache configurations often cause crashes. Consider using ThrottleStop to target just the core, not the cache. This approach may succeed on some systems but not others. Test Cinebench with and without core-only voltage offsets to observe performance or temperature changes. While Cinebench isn’t ideal for stability testing, its outputs remain fairly consistent across runs as long as thermal or power limits aren’t triggered. ThrottleStop can also reduce the cache’s maximum speed. Some motherboards automatically cap cache speed at the CPU base frequency—around 3.70 GHz for the 12600K—which lets you undervolt further without BSODs. Set the Cache Ratio Max in the FIVR window to 37 for control. Another option is the new ThrottleStop 9.6.5 feature, which lets you tune only core voltage without affecting cache voltage. This could offer a practical fix. TS 9.6.5 will likely be available soon.
