I need your help to start investigating the causes of esporadic BSODs after OCing a i5 760 @ 2.8 GHz to 3.6 GHz. After many years without getting myself into these adventures, I lost track and find myself pretty much in the dark.

The machine is a good machine built by one of the best folks around in the country. Comes from a company called F13PC built from enthusiasts and, I'll say, gurus. Specs are:

  • Chassis NOX COOLBAY Side Window with 2 fans
  • Motherboard ASUS P7P55D-E Socket 1156 (Sata 6Gb/s & USB 3.0);
  • Intel Quad Core Core i5 760 2.80 Ghz, OCed @ 3.60 Ghz
  • Cooler Artic Cooling Freezer 7 Pro Rev.2;
  • Gskill Ripjaws 4 Gb DDR3 1600 Mhz CL8 Dual Channel;
  • ASUS GEFORCE GTX 560 TI DC II 1024MB GDDR5;
  • Samsung 1 Tb 32 Mb SpinPoint F3;


The BIOS includes two profiles. One for OC and the one with the stock settings. Under the OC profile I get the occasional BSOD. Sometimes not long after booting, other times only after long hours of uptime. BSODs happens even under nominal conditions, like while doing stuff on the desktop. The BSOD dump goes too fast. Before I can take a good look at the error, the machine is already rebooting, bless her.

Temps under OC seem normal. The CPU cores don't exceed 47 ºC (116 ºF) when idle and can ramp up to 70 ºC (158 ºF) under heavy load in just a few seconds. But I haven't seen them ever exceed 80 ºC (176 ºF).

My hope is this isn't a stability issue, but a driver issue. The GeForce is just a few weeks old. Was launched last month and the drivers are very new. It isn't even supported yet by Nvidia System Tools. However, the machine doesn't seem to want to BSOD when I switch to the bios profile without OC.

How can I start investigating this BSOD? The OC resulting performance ramps up the CPU very high, giving it i7-960 like performance. Not that I couldn't live without it. Far from that. But seems a shame to miss the opportunity.
