Is there a version of your miner that will work with my HD 6990 cards (essentially 2 6950 or 6970 GPUs on one card)? And if so, what must I do to obtain it, and set it up for my cards?
The AMD driver site said the newest Catalyst my cards could run is 15.9 (not 15.12). When I ran them a couple years ago, they were mining with Catalyst 14.6 (on a mining OS called PIMP-1.5.4-amd-14.6-r2). I am disabled, and have a limited income, and therefore must run what I have. Thank you.
I have a 6990. Use drivers 15.7
And mine ETH with it with his miner software not ZEC. ZEC will run at 2Sol/s per core so 4Sol/s.
With ETH you will get 13MH/s each so 26MH/s total. Almost the speed of RX480 & 390 just uses alot of power.
You can also undervolt them to like 1.0V to save on heat and power.
