Prime 95 continues to run after several minutes without any crash in Windows.
Hi guys,
I'm just starting out with overclocking.
My setup includes an i7-8700k on an MSI Z370 A-pro board, 32 GB DDR4 RAM, a Duke GTX 1080 Ti, and an EVGA CLC 280 with 4 Noctua ippc 3000 chips in push/pull mode.
Currently I'm at 4.8 GHz across all six cores with a 1.195 Vcore. AVX is set to -3 and LLC mode is 4 (straight line).
I ran a Prime95 version 26.6 small FFT and reached a maximum of 57°C. This test lasted for 8 hours without any issues.
Now I'm trying to lower the minimum Vcore needed for 4.8 GHz. I've experimented with values like 1.19, 1.185, and 1.18.
For these settings, my system boots normally and runs games smoothly. But when I run Prime95, it works for about 30 minutes before suddenly shutting down (the program just exits without any BSOD or crash).
There was no error message or crash at all—just a clean exit.
What issue am I facing? Is there some kind of throttling happening?
Any suggestions to improve my overclock?
Thanks for your help!
TBH, you've got a decent all core OC with very nice voltage, and excellent temps for Prime stressing. There isn't much more to tweak. You can try bump the LLC up one notch, and try the lower voltage, but keep an eye on the temps.
Apart from that, the exits for Prime seem like a glitch, so maybe update to latest version. It could be linked to the lower Vcore, but then Prime should fail a CPU test as opposed to just exiting. That's the purpose of it.

Right you articulate my problem very well. That was exactly what I was wondering.
Because when I tried vcore values like 1.7 or 1.65, prime would run for like 1 minute and windows would crash, I would get a blue screen. This way I know for sure my oc was not stable.
However for those upper values, prime just simply exits after 20-30 minutes and the system remains running perfectly fine. That's why I was confused
🙁
Ideally you wouldn't manually adjust your vcore above 1.4 with Intel chips. A value of 1.651.75 poses significant risks. During auto-setting, when cores boost, voltage spikes can occur—normally reaching 1.4 to 1.5. Monitor voltage levels using HWMon and be cautious with the LLC setting; it can sometimes cause overvoltage. Overall, you're in good shape. Apply the latest update and observe your performance. With some adjustments, achieving a rating of 4.9/5 at voltages between 1.2 and 1.3 is possible.
Roland Of Gilead says it's usually not necessary to manually adjust the vcore above 1.4 with Intel chips. A value of 1.651.75 is quite dangerous. When auto-setting increases, voltage spikes can occur occasionally—normally they reach 1.4-1.5. Use HWMon to monitor min/max voltages. Consider raising the LLC setting slightly and watch for unusual spikes. LLC can sometimes overvolt, so proceed with caution. Overall, you seem fine. Try the latest update and see your results. With some adjustments, you might achieve 4.9/5 at voltages between 1.2-1.3+. Oh god that went terribly wrong. Typos... I meant 1.17 and 1.165 LOLLLL... Yea, I don’t want to know what would happen with a 1.7 Vcore... Anyway, appreciate your input.

In general, it's not necessary to manually adjust the vcore above 1.4 with Intel chips. A value of 1.651.75 could pose risks. During auto-setting phases, when cores boost, voltage spikes may occur—this is typical and usually ranges between 1.4 and 1.5. Monitor with HWMon for minimum and maximum voltage readings. Consider increasing the LLC setting slightly and be cautious of unusual spikes. Using LLC can sometimes cause overvoltage, so proceed with care.
As far as I see it, you're fine to proceed. Apply the prime update and observe your performance. With some adjustments, you might achieve a rating of 4.9/5 at voltages between 1.2 and 1.3.
P.S. Typos again... I meant 1.17 and 1.165 LOLLLL... I don't want to find out what happens with a 1.7 Vcore...
Anyway, thanks for your input.
No worries, you're welcome. Feel free to reach out if you need more assistance. Have a great weekend.
