Title: which miner support GTX680? Post by: omo on April 28, 2012, 02:57:37 AM I just bought a giga-gtx680 and want test hash rate for mining.
I tried cgminer, a black screen happended.. I tried ufasoft miner, it just exist. which miner support gtx680? Title: Re: which miner support GTX680? Post by: scifimike12 on April 28, 2012, 04:08:48 PM There isn't much support for Nvidia cards, especially with the GTX 680. But a member did compile a small miner to test out:
I have tried to recompile the Ufa-miner and the rpcminer-cuda, but for various reasons it didn't work. Now I have written a very simple miner using the latest CUDA toolkit, just to see what the speed is like. Since I have written the kernel from scratch, and the program is not doing longpolling, there's some room for improvement. If somebody with a GTX680 would like to try it you can download it there: http://www.sonstiges.org/bitcoin/ICU-Miner.zip (http://www.sonstiges.org/bitcoin/ICU-Miner.zip) Usage: Code: ICU-Miner.exe URL username password devicenumber gridsize blocksize For example: Code: ICU-Miner.exe http://mining.eligius.st:8337/ 1BtVLjUkAzF9wZGHfKzzsPivgNAn4DTp1Q joshua Here's the ugly source code: http://www.sonstiges.org/bitcoin/ICU-Miner-source.zip (http://www.sonstiges.org/bitcoin/ICU-Miner-source.zip) Unfortunately it didn't do as well as we had hoped. The most I was able to get out of it was ~94 Mh/s. Title: Re: which miner support GTX680?

http://www.tomshardware.de/geforce-gtx-680-test-benchmarks-Kepler-GK104,testberichte-240979-15.html The CL Performance is much more lower than the 580. Title: Re: which miner support GTX680?

I downloaded icu-miner and make it run, I also got ~96MHZ/s, and about 200W power consumption(~90w when idle) Unfortunately it didn't do as well as we had hoped. The most I was able to get out of it was ~94 Mh/s. Title: Re: which miner support GTX680?
