My system overclocked to 4.5ghz was rock solid for nearly two years, but suddenly I've been getting random blue screens with "whea_uncorrectable_error". I built my current rig in June 2011 with:
- ASUS P8P67 Pro
- 2500k
- Noctua NH-D14 dual-fan heatsink
-8gb of ram (2x 4gb)
- 560ti gfx card
- Fractal R3 case
I immediately OC'd by only adjusting two settings:
1.) up multiplier to 45, taking the cores to 4500mhz
2.) adjust the VRAM Frequency from 300 to 350
The only change is I'm running Windows 8 64bit, and I've upgraded the BIOS to 3602 (the latest version on the ASUS page). Running Prime95 in blend mode will trigger the crash within a few minutes. Sometimes it successfully reboots, sometimes it hard locks (if it hard locks, it takes down my router's internet connectivity with it - see below*).
Restoring BIOS settings to factory seems to make it pretty stable, I've run Prime95 multiple times for a few hours at factory, but haven't had crashes each time. I've tried cleaning out the inside and resetting the ram and video card - the only thing I haven't tried is resetting the cooler, but right now it's idling at 31c and jumps to 42c after 20 minutes with Prime95 running, so I feel like the cooler is doing its job.
Any ideas as to what would suddenly cause the instability? Any suggestions on how to troubleshoot it?
* If the machine hard locked after a blue screen, it would also rendered my router's internet connection unresponsive. It was the strangest thing, the computer is connected by Ethernet to one of the router ports, but once it locked, the router was somehow overloaded - if you were connected by wifi at the time, you could access the admin interface, but you couldn't access it remotely, and all internet activity was shut down. Restarting the computer restores the connection without any additional interaction with the router - it's important to stress that the RT-N16 router seems otherwise unphased other than its inability to communicate with the internet during the rig's lockup.
