still fiddlin with mine right now . . . I can run the card stable at 614/742, but over that it gets a little buggy. I've been trying to tweak the DRAM timings on the card, but it's a slow process cause I've got to flash the BIOS for every change. But I've had some success with it so far, but the timings don't make much of a difference OCed. I ran 3m06 and got 4039, then after playing with the timings I pulled 4429 at stock speeds, but running OCed only yeiled a score of 4582, which is only 40 marks higher than the score I submitted here . . .
Just trying to find the sweet spot!
thought about volt modding your card and raising your agp/pci-e bus speed that normally helps stability of overclocks and might be able to cram another few mhz
I've raised the PCI-E BUS speed on the mobo, the voltage to the slot, lowered the latency a little, and bumped up the bandwidth - but doing all that only gave a few extra points in a final score. Lowering the DRAM latencies and increasing the refresh rates I can run the mem about 756 with a lower core speed - but haven't tried that out in 3m06, yet.
Haven't vmodded the card yet, though - know where any info is on those specs?
