Meanwhile, I have purchased some second hand 7950s from ebay which are much cheaper, run colder and almost as fast as the 7990s. The biggest problem i have had with the 7990s is the massive heat buildupm. Keeping them under 80c is a challenge, so I have had to underclock and undervolt the 7990s to best extend the life of the cards. Im thinking watercooling is essential to get the most out of a 7990.

So I got a second one of these cards and can't seem to get it working properly. After about 2 minutes of mining the rig will shut off for 5 seconds, and then reboot. It seems like a power issue but I am using a 1500W PSU and have both cards separated with 2 powered riser cables. After some playing around I found I can get the rig running only under certain settings. I can run any 2 of the GPUs at intensity 19, enabling a 3rd will cause the reboot. I can run any 3 of the GPUs at intensity 13, enabling the 4th will cause the reboot. I can run all 4 GPUs at intensity 8 but its pointless. Can anyone offer any ideas as to what is causing this? The motherboard i am using is an Asus P7P55 LX (8gb RAM). A bios update had no effect.

Quote from: Trillium on June 28, 2013, 07:31:43 PM This card is already close to the maximum number of watts than can be handled by its VRMs and the PCI-e connectors/cables. I would not recommend increasing voltages to try and get more kh/s something will fail somewhere. Remember that in the low-voltage high-current world of GPU's even a tiny increase in voltage can result in a much increased power consumption and hence thermal output (Power = VoltsAmps). You'd be much safer with 2x 7970's. I wasn't going to increase voltages on such a new and pricey card. Doesn't the 7990 use less power? Since Electricity costs are my main concern, I thought it better to go the single 7990 card even if it was more costly that 2 7970.

It does sound like an interesting idea. Any plans to add DGC to the mix?

I have been waiting months for my jalepeno. Even if they do ship it by the time i get it 5GH/s wont even be worth it. They should offer to upgrade units for free every month they are delayed. Of course, this wont happen

I'm sure it's just a typo but in the subject line it says conmerce. CON-merce hehe Reminds me of a dilbert cartoon where dogbert wants to con and insult people at the same time so he becomes a consultant.

Greetings, I am using a Gigabyte 7990 (Malta) for Scrypt mining and I wanted to see what results others have had. using CGMiner 3.2.0 with the following: cgminer --scrypt --temp-cutoff 90 --shaders 4096 --intensity 19 -o stratum+tcp://[epools] -u [username] -p [password] and i get 1300 Kh/s with GPU @ 1000 MHz & Mem @ 1500. Using windows 7 currently, linux doesn't seem to have drivers available yet. Can anyone top 1300 or help me push it a little further? Havn't been game to mess around with voltages / powertune. Cheers

Greetings! I am new to these forums too. Eager to bust out of newb jail to get in on some group buy deals. The Asicminer usb eruptors look good. Who else thinks so?
