Also does the mem clock OC benefit work times much?
BOINC is more efficient, as it does not need to use VRAM, nor depends on the bandwidth, so you can reach higher clocks with less voltage by severely downclocking the VRAM. Check the validations on my sig.
Also, it is more forgiving with higher speeds. BOINC can happily cruise happily @ 895 MHz @ 1.150v on my cards (those are BGB clocks, for power crunching i settle for 860-875 MHz @ 1.125v, and everyday crunching i go for stock clocks), but for stable gaming it gets only up to 850 MHz at the same voltage (i have gotten it to 890 MHz for benching, but it is not too stable). I'm too afraid to really add max voltage (1.212v) because i'm lacking on cooling (my waterblocks are universal ones with Artic cooling aluminum heatspreaders) but i bet i could get them to 925 MHz stable on BOINC with good enough cooling.
I hope to find cheap full-cover waterblocks for my cards.
