Short freezes after OC
Short freezes after OC
Good evening everyone,
I encountered an unusual problem with my overclock setup. The overclock itself remains stable during testing (30 minutes with AIDA64 and another 45 with Prime95), but when gaming, loading files, or watching YouTube, I experience brief half-second freezes accompanied by a BRRRT buzzing sound. This occurs roughly every 20 seconds in games, and it seems to become more frequent as the session progresses. I’m unsure what might be causing these interruptions, since stress tests don’t trigger issues and temperatures stay within normal ranges (max 65°C on CPU, around 60°C on GPU).
My system details:
- Coolermaster G550M 550w PSU
- Arctic Freezer 13 CO Cooler
- ASUS P7P55M motherboard
- i7-870 @ 22*165 MHz
- Windforce GTX 960 (Core Clock + 90, Mem clock + 550)
- 2 x 4 GB DDR3 1333 MHz
Some users have reported similar issues, though they often remained unresolved. I increased my VCORE up to +0.15, but the problem persisted. Could you help identify the possible cause?
Thank you and best regards

Keep in mind they didn't have my exact motherboard, just the standard ATX options.
My PSU appears adequate, but it could face issues when a core hits full capacity. This might also account for why the problem shows up more often in older games that run on a single core (observed in IL2-1946).
Yeah, that's odd... I assumed it was a PSU problem, but it could still be. You often see unexpected shutdowns or stuttering if that's the case. It might also be related to the motherboard chipset. ASUS says you can't increase the core clock beyond 500mHz (at the bottom), which is low even with a higher CPU. I’ll take it off now just to avoid damage. I broke my R9 280X a few years ago after doing a bad overclock in War Thunder.
They are referring to the 500 MHz limit in the BIOS settings, which is the highest base clock you can configure there, though it depends on who sets such a high frequency. For the PSU, you might try lowering the voltages slightly and possibly adjusting the GPU overclock a bit. Right now my GPU runs at +5% voltage and my VCORE at +0.05.
Sure, let's clarify this.
Yeah, you're correct... it's definitely not a high overclock, which is why I'm still trying to figure out what it actually is.
Quick update in case someone finds the thread in the future:
I upgraded to a P7P55D motherboard, which is the ATX version. It has significantly larger heatsinks and is more robust for OC in general. So far I did not have the same issues at 183*20 MHz. I will update this post in case the issues return and I find a better answer than to upgrade
