Hello, long time reader on here but this is the first time i have posted. I'v got 2 sapphire 6970's in crossfire and they are about 9 months old. few months after I got them I put a ARCTIC COOLING Accelero XTREME Plus II on each one, they stay pretty cool, in crossfire the top card gets about 72x and the bottom 60c for a long time, about 5 months or so I'v ran a mild OC core was 910/880 and mem 1400/1375. when the cards were new they could do this stock but then I got BF3 and i had to bump the voltage just a bit, stock v 1174 and i bumped to 1181, very minimal bump but it worked. about a month ago they just started freezing in any gpu intensive situation, now they wont even run at stock, i run 860core 1350mem and i have to turn the volts up to 1189, even then if everything hits just right in BF3 it locks up, i can't believe my cards would degrade like this over 9 months with the temps always being so low and the OC i ran was so mild, but i guess they have, thought i would run it by you guys and see what you think
forgot to add, each card works just fine by itself, but in crossfire i have to have them in the order they are in, if i move the bottom card to the top and the top to the bottom and run crossfire, they are really unstable, its odd they both run fine by their self which is why im not 100% sure they r going bad, but everything has been fine for 9 months, also I have tried different drivers all the way back to 11.11
