I built a big cluster with the idea of putting 6 gpu's per machine. That didn't work out ... I ordered over 100 cards and have these remaining, still unopened in the box. These cards are the latest revision of the PCB which runs cooler than my previous rev cards.

The card features a dual bios which flashes easily and screw ups are easily remedied by flicking to the alternate bios. Unlocking these cards has worked about 60% of the time for me and I can provide a proper bios with the unlock, but I will not unlock the card before shipping. Flashing the bios is your own deal, your own risk.

Stock clocks of these cards is 800 mhz, I've bumped them up to typically 900 mhz and some even higher. I typically can get about 360+ mhash/sec from a shader locked card and just under 400 mhash/sec from an unlocked card.

The card features a large heatsink and dual fans. In my setup I'm running 20 machines each with 4 cards with no risers. Cards are very close together only using a plastic DVI dust cap to space the cards from each other. I've ran this setup for 9 months with no fan failures. I've now survived an entire summer (up to 95F ambient) and a winter running outdoors (down to 25F ambient).

I'll accept 40 btc (exchange rate dependent) or $220 MTGOX USD cash redeem code per card. I'll do PayPal also, but you pay the fees. Shipping costs depend on where the card is going. I will of course combine shipping for purchase of multiple cards. I will also entertain discounted offers for multiple cards.

I will provide a receipt that should provide full warranty (unopened, new in box, etc) of 2 years. I can only assure warranty from the data of my purchase in August. But in short you can rest assured as even in a pinch I would be willing to file RMA via proxy if it was needed.

Here is the output for cgminer running on a system with 4 of these current revision cards; The second card is shader locked. The other 3 are unlocked. Mind you the temperatures and fan load are at 55F ambient.

This is a legit, no scam offer. Catch me in irc on FreeNode in #ozcoin. My handle is sunbreak or sunbreak2.

Here is a pic of the new cards next to my cluster. Sorry, not the best pic, but evidence none the less.
