After reading Anandtech's disaster, I wouldn't recommend it... I notice no difference here at 450FSB with 1.3 or even 1.4... And plester I hope ya CPU doesn't run into trouble as 1.5Vcore compares to about &.6Vcore daily for these 45nms... I would go again back to 4ghz 1.4Vcore... or sell this sucker and get another one...
