On the last page we covered how overclocking on the ZOTAC GTX 680 works using the PrecisionX tool but what was our maximum overclock on this card?

By maxing out the power target slider we found our stable core offset was +153MHz with memory offset of +540MHz, This allowed our card to peak at 1264MHz core with full stability and memory hit 1772MHz (or 3544/7088MHz depending on the calculation used). This gave us a 3DMark Extreme profile score of 3650, 500 points better than the reference settings.
