hi guys, ive just been reading this thread and have a similar system myself. i cannot for the life of me get any overclock to stick no matter what i try. only real difference is i have 8gb of ddr2 800mhz ram and 4870 in crossfire.
issue is once i change the host setting to 320 for example and try and change the ram multi to resemble 800mhz, save + exit. it will post right up until the memory test to which it will then shut down and revert back to stock settings. it's really quite frustrating.
any info would be greatly appreciated.
