How does memory speed affect performance since I am getting a hard time upping speeds stability without upping voltage because it gets too hot. I'm not at home right now so I'll post here since I can't test. Say, 1125/1575 vs 1200/1375, which would offer better performance? Or something closer like 1125/1575 vs 1150/1400. Because right now, I'm upping core clocks and memory clocks so I'm thinking it might be more stable if I lower memory clocks a bit to clock core higher.

It all depends on the games you play. Whether theyre GPU memory intensive or more CPU intensive.
I find that 1150/1400 is balanced and works good all round.

I've been jamming hours of BF3 with 1200/1700 stock voltage and my fps went up significantly from stock.

Guys ive noticed major conflicting with using CCC with the overclock. Make sure it is DISABLED and also disable Powertune.
Doing so has allowed my cards to overclock higher without the freezes in games and benchmarks.

Thanks, so in simple terms for a game like BF3, it seems it is both memory and CPU intensive, clock for clock, overclocking the core would be more beneficial.

Yeah the core always is. Overclocking the memory is a little less beneficial to the overclock but it does help.

Good advice.

For stability I found crysis and warhead to put the most hurt on my gpu. I can do 1250/1850 in every other benchmark, crysis 2, bf3. Clocked down to 1230/1700 for crysis and warhead due to little flashes while playing.
