If its an ATI card turn off the "whateveritisthatssupposedtorecoverwhenitbugsout" also if you are overclocking are you sure you locked the PCI-E bus at 100Mhz?
It's BFG GTS 8800.
I don't think it has a "whateveritisthatssupposedtorecoverwhenitbugsout" I think thats Vista's self preservation.
I've had a replacement motherboard and memory so far and it's still not very stable. It's ben running at 2.7GHz 300 * 9 for ages running setiand now it suddenly having problems
I've knocked it back to 266 * 9 (stock)
PCI-E has always been set to 100MHz I assume that implies a lock too, as you can set a specific frequency.
I wonder whether I need to RMA the graphics card instead.
Everyones been very helpful both here and the tech support I've spent a lot of time on the phone to and no one seems to have any idea why it's not working properly lol
