System stabil bei niedriger Spannung, aber Startprobleme bestehen.
I recently moved from a 12600k to a 13600k. Right away I started with some undervolting and possibly even overlocking if the chip supported it. The changes were small mainly to cut heat and power use. What matters is that I ran stability checks to verify everything was fine. About an hour of OC tests passed without any problems; Cinebench R23 and R20 can each last 30 minutes. Y cruncher works perfectly, and aida64 doesn’t cause any crashes. The chip stays under 280mm and temperatures never rise above 75°C. I’ll share my specific overclock/undervolt values later if they help. My main problem is that my PC won’t cold boot properly. It restarts fine, but leaving it off for a while makes the fans spin loudly without any post or boot. I have to press the power button to shut it down, then restart a few times. Eventually it shows up a screen saying “overclock failed” and I have to press f1 to adjust settings. From there I either raise or lower the overclock offset by 100MHz, save and reboot, and eventually get back into Windows where the overclock/undervolt works smoothly. Relevant details: MSI Z690-A DDR4 board with the latest BIOS 7D25v1l1 (beta version), though it still had issues on 7D25v1H; the beta BIOS was a troubleshooting step. I’m running a 32GB 2x16 Kingston Fury DDR4 at 3600MHz CL 16-20-20-39 with XMP settings. In BIOS, voltage offset mode is set to -0.090V, short-term power limit 205W, long-term 180W. Load line calibration is on mode 3, Intel power mode on mode 5, and a 100MHz boost on both P and E cores. There’s also a 200MHz boost for the P cores when changing settings to get a boot. Fastboot is disabled in Windows and BIOS, which might be part of the issue. What could be wrong? Are my adjustments too aggressive? I’m puzzled—how can it pass all tests but still struggle with booting? I’ve searched extensively but haven’t found a clear solution. Thanks in advance for any insights.
Interesting observation. It's working fine when using only XMP, and the BIOS fastboot feature is active by default. The issue seems to be caused by the undervolt setting.
Sometimes undervolt behaves oddly, stays steady during long stress tests but then crashes unexpectedly on the desktop or won't start at all.
It seems you're experiencing challenges with CPU performance during startup despite stability in other tests. You might want to continue adjusting settings and increasing the voltage to see if it improves things.
Think about using ThrottleStop for controlling your undervolt settings. Adjust the BIOS to default voltage, and apply the undervolt only after logging in and when ThrottleStop begins. Another helpful option is the Sleep Defaults Voltage setting in the FIVR window. Checking this box just before sleep resets the undervolt to zero, and it won’t reapply until you restart. When using Windows Defender, look at the ThrottleStop Options window for the Windows Defender Boost box. This often leads to more stable benchmark results.
Usually I'm wary of extra applications on my PC when the BIOS runs smoothly. However, after trying again with more conservative configurations back at home, it still didn't boot. It looks like to manage heat and power limitations on Intel's newest chips, I might need to install Throttle stop or Intel XTU. Appreciate the advice!
Thanks for the updates. PDifolco clarified the issue was with my settings, and unclewebb provided a helpful solution. I’ll close this now.
