As the Zotac GTX 480 Amp! runs considerably cooler than the reference design we decided to try our hand at some manual overclocking.
Although the reference GTX 480 is an extremely high performance board, it appears there is a decent amount of headroom on the Zotac AMP! Edition. Zotac told us that they hand pick these cards for maximum performance so while we can't guarantee a card you would buy could hit these speeds, we are confident there will be a little headroom over the reference clocks.
