Title: why cant i get my xfx hd7970 above 540 kh/s Post by: moork666 on January 19, 2014, 12:04:22 AM Hi Everyone,
it seems that i cant get my xfx hd7970 hashing faster than 540 kh/s. I bought that card long time ago and it wasn't meant to be used for mining. However why wouldn't it mine like the omes shown at lite coin hw comparison list? regards Title: Re: why cant i get my xfx hd7970 above 540 kh/s Post by: ImFade on January 19, 2014, 12:22:09 AM It looks like you're close to it's max. I am still a newbie here so I am just taking a shot in the dark since nobody has answered this post yet. But have you tried to update your drivers? Maybe that will help, anyways best of luck!

Going from an old bios on my Gigabyte7970 to the newest one increased my hashrate from 550 to 740kh.

I assume that it has to be the bios. The problem is to find a "working" or "better" bios. regards |
