Get the answer spentshells a b K Overclocking June 6, 2013 4:15:34 PM I can't find the tool I used it was an older ati tool, it seems the ati page I was looking for is gone (no more ati) Core I simply ran at 960Mhz with catalyst and mem 1350Mhz The memory overclock can go much higher 1450 i've seen as almost normal, remember the best oc you can get is the highest from the worst of the two cards, If I find the tool later I will come back and update but let me tell you it does not support crossfire so it's really of no use BUT it does allow you to alter voltage on voltage locked cards m 0 l icraft a b K Overclocking June 9, 2013 8:03:23 AM spentshells said:BUT it does allow you to alter voltage on voltage locked cardsUnless it's hardware locked. I'm bumping this incase you find that tool, because I want to increase my voltage a bit, and it's locked. m 0 l kansasboy001 June 10, 2013 9:28:26 PM icraft said:spentshells said:BUT it does allow you to alter voltage on voltage locked cardsUnless it's hardware locked.
