Re: Low hashrate on 7970 scrypt? Under 700Kh/s? Here's what to do...
Hi, to refresh a subject a little bit 
I have 4x 7970 Sapphire DualX cards and I obviously have an issue with them. I cannot pass the 600 Khash barrier with them even on 1150GPU and 1650MEM with 1175 voltage.... Thread is on 8192, w256, I13 threads per gpu 1....
I tried to flash bios with the one from the first thread and nothing.... Then I reflashed bios with the one from the website for my card and I did it good but no change in hash rate.... So, does anyone knows what bios should I use to improve hash rate?

So if we're flashing the bios to the Dual-X then I don't think you need to flash the bios at all, IMHO. I think you just need to tweak your settings until you find the sweet spot. It's a tedious process, especially if it's your first mining rig.
