Overclocking my Powercolour 3870 XT !!HELP!!

Hi,

I purchased 2x Powercolour 3870 XT's from OcUK and when I clock them say 20mhz above stock clocks, and then run 3dMark06 I recieve errors usually on the last test.

The test just stops and reverts back to Vista desktop and says driver failed to load or something along those lines.

My Setup is:

Asus Maximus Extreme - 0905 Bios
OCZ PC 8500 DDR3 ReaperX x 2Gb Modules
Q6600
Enermax Galaxy 850 Watt
WD Raptors 36gb x 2 in raid 1
Seagate Barra 500gb

Case is the Nvidia Gamers Edition and has all occupied fans running at full tilt so I cant see this being a heat issue.

Could this be something to do with Vista and the drivers ?

How are you oc'in them. If its Ati tool, I've heard thats not great under vista and with the 3870's

atm I have been using CCC.

these errors though is it something to do with vista or overclocking the cards because I should easily be ok with overclocking 20mhz over the stock frequencies.
