Anybody uses Sapphire 7970 with 6Gb onboard for scrypt mining? What is the hashrate difference between 6Gb and 3Gb boards?

I imagine that V-RAM would have approximately zero % effect on mining.

i also think ram has impact in scrypt performance, i have only 2GB , win7 32bit

i have gigabyte 7970 with gpu clock raised from 1000 to 1100 , on bitcoin i get around 650 MH/s

but with scrypt i use GUI Miner - Scrypt , and it only works with "7970 (low usage)" profile, getting around 560 kH/s...

i also use pci-e 16x->1x extenders with molex power , i don't think 1x bandwidth has a negative impact on scypt performance
