About 2 weeks ago, I oveclocked my Asus 5870 to 1010 mhz. It was running fine at 1200mV, but I raised it to 1250mV to be safe. I have ran MSI Kombustor for a maximum of 5 minutes (because the temps never went higher than 68-70C ) I have played Cod MW2 and BFBC2 countless times since then, and I am 100% sure that it is stable. I added you on msn to send you some screenshots if you want.. But I don't feel like running Kombustor for 15 minutes lol. I just dont really see a point. I have also ran heaven benchmark, 3dmark06, 3dmark vantage and RE5 benchmark. Accept my add on msn because I would love to be part of the club.
