How do I overclock CF 7900 series cards that have different mem clock speeds?

post #1 of 2
Thread Starter 
Basically, what I have done is purchased a 7970 and CF it with my 7950, but my 7950 mem will not go past 1250 without crashing, so do I need to downclock my 7970 mem to 1250 as well or disable "synchronize cards" in sapphire trixx? I'm assuming I need to disable synchronize cards in sapphire trixx options?

just installed 12.8 drivers... this is what I got http://www.3dmark.com/3dm/1021399?

it shows both my cards as 7970 and at 1000/1450 did ccc do this automatically or is it just an error my 3dmark reporting?

i can't get a stable OC either, my 7950 used to be stable at 1200 core before addinga second card, i left the 7970 at default and put my 7950 at 1200 core like before and it crashes everytime... :/
