Looking to get out of the mining game for now as my priorities have changed. I was consistently getting at least 5 MH/s running the 6 cards below.
The 6950s (2GB) have both been flashed and unlocked to 6970s. Remaining one is a Twin Frozr II model that I had running under water so temps were always less than 60C. Getting 500 to 510 kH/s per card. Looking for $160 shipped
One Asus 280X DC2T left with custom STILT bios flash. $360 shipped
Finally my 2 prized 7990s. These are the Malta GPUs, not 2 Tahiti on the same PCB and have 6GB of memory. They are Sapphire cards with dual slot coolers (I know some manufacturers have a triple slot). Undervolted each core by 0.1v or more, depending on clocks. Getting 1.3 to 1.4 MH/s per card, usually saw WU between 2300 and 2600/m for the pair. $825 shipped per card or $1575 for the pair. These will also be listed on Ebay as they seem to go for a premium over there.
I'm located in San Diego, CA and local pickup is definitely an option. I have heatware under aznblueeboi. BTC and Amazon payments preferred. Paypal is accepted.
Thanks for looking!
