Title: 6990 Hashrates? Post by: Cablesaurus on March 27, 2011, 06:35:43 PM Wondering if anyone's seen performance and hash rates on the new 6990 card?
Title: Re: 6990 Hashrates? Post by: Garrett Burgwardt on March 27, 2011, 08:39:01 PM Mine hashed away stock at 300 mh/s per GPU - but ther are some bugs with the driver, hardware accelerated stuff doesn't play nice with running miners. PITA.
Overclocked to 900 mhz, I get 350 mh/s :) Title: Re: 6990 Hashrates? Post by: Cablesaurus on March 27, 2011, 09:06:04 PM How does its power consumption compare to the 5970?

PITA. Overclocked to 900 mhz, I get 350 mh/s :) try: http://bitcointalk.org/index.php?topic=4292.0 will definitively help with temps and power consumption. My power consumption is lower than stock, yet I have a ~17% OC on core and ~23% increase in Mh/s NO voltage change Title: Re: 6990 Hashrates? Post by: Garrett Burgwardt on March 28, 2011, 10:32:37 AM I game with my card too, so I'll pass on gimping the memory clocks.

If you're on Windows, it's very easy to set up profiles with ATI Tray Tools and definitely worth it.Title: Re: 6990 Hashrates?
