Title: Sapphire 7970 6Gb scrypt mining Post by: pocopoco on May 05, 2013, 04:42:42 PM Anybody uses Sapphire 7970 with 6Gb onboard for scrypt mining? What is the hashrate difference between 6Gb and 3Gb boards?

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 |
