Card: EVGA GTX760 FTW 4GB
CPU: Intel core-i7 3930K @4.5GHz
RAM: 16GB Corsair Dominator Platinum @ 2133MHz

GPU overclock--Offsets: +95 gpu clock, +800 mem clock... Results--max core: 1280MHz; mem: 3802MHz

3DMark11, Performance: 10385
3DMark11, Extreme: 3748
Heaven 4.0, 1080p, max settings: 39.3fps, 991 score

These results seem fairly decent to me, but I'm new to gpu overclocking, so please tell me if I'm wrong. And now, to OC my other card! W00T!

Well, I seemed to be stable at +157 but memory was being finicky. Eventually I was getting through benchmarks at +157 and +300, but any game I tried to play would crash or just completely lock up my computer. So I tried to lower the core again to around +140 (about 1250 max clock) and then get the memory stable but it was crashing in benchmarks again, even at like +50 memory offset. After that I said screw the memory and just boosted my core and I've been running smooth all day. It's unfortunate because I noticed substantial improvements in benchmark scores with the memory OC'd but if it's not stable in actual games then it's kind of pointless. Are there any real tricks to boosting the memory? What should my ratio of core to memory offset look like?

Also, idk if i'm blind or what but I never see artifacts during Heaven with a high memory clock.

1241 may be your MAX core clock, you can't force it up if that is the maximum
my max clock on my slot 1 card is 1215
max on second is 1260 something, it's luck of the draw.

What is the max boost clock? The offset values doesn't mean anything when comparing, really smile.gif
