Ive had my tbird 800 for about 6 months and so far the highest ive been able to OC it is @ 950 1.85 vcore. Im using a Taisol CGK742 and Arctic Silver. It will post at 1 Ghz but I cant get any further than the bios screen. Its green core if that makes any difference. Does anybody have any tweaks to squeeze a few more volts outta my A7V to hit 1Ghz Stable??
