Well i did OC it and yes it stuffed up again

The same thing happened to my Asus P5K last month, i had it replaced under Warranty because it was found faulty.

Current Rig:
E6300@2.8ghz
GA-DS3R
2GB Kingston DDR800, 5-5-5-18
XFX 8800GTS
Creative XFI
Antec 550W PSU, 3x18A

Firstly 400FSB, mem 2.0@800mhz, cpu v 3.335, locked PCIE@100mhz booted fine at 2.8ghz as you would expect. Went into WinXP and ran Orthos small ffts for 24hours. No problems, temps at 49deg full load. Opened a couple of games and there you go, same problems as last OC. see screenie below.

Rebooted, Went back to stock clocks immidiately, into windows, tested game again at stock settings, same problem. Formated hard drive, re-installed XP, drivers, and a couple of games....same problem...took out motherboard, using a spare Asus P5B for now.

Once again the mobo has sustained permanent damage.

BTW it's not the video card or PSU, i had it running for days without problems until OC'ing.

Any idea how this could have happened?

That sucks.

Overclocking is luck of the draw. No guarantee everyone will get the same results even with the same parts. And there's a risk in o/cing. This is one of them.

Are you sure the vcore is 3.335v & not 1.335v?

Disconnect everything, let them cool down, wait for a day, clear cmos, try games at stock.

Put standoffs on the mobo tray before you mount the MOBO to it.

hehe hehe

3.3V Vcore is definately your problem.

"running for days without problems" is NOT a valid claim that its not your PSU or video card. Your video card AND/OR you PSU may not be able to handle ANY OC. Period. You OC may be the problem.
