Hi there! I used the method mentioned here(with RivaTuner plugin) to further overclock my 4870 but with no success. Without volt mod i was able to reach 800 mhz on core. 830 Mhz was not stable it was crashing from time to time in Crysis benchmark. I tried to increase vcore only a bit and increased core to 830 but Crysis was still unstable and it hang even faster than without voltage increase! Continuing to increase volltage led me to nothing - benchmark was hanging faster to faster My 4870 is cooled with Accelero S1 and Turbo Module upon stock RAM and VRM cooling. Anu suggestions?
