Title: Mining with a GeForce 8600M GS?
Post by: Galane on April 13, 2014, 09:22:15 AM
I have an MPC TranSport T2500. 4 gig RAM, 2.5 Ghz Core 2 Duo, GeForce 8600M GS with 256 meg dedicated RAM. I put Win 7 x64 Ultimate on it. Verra nice-a with the 1680x1050 LCD. MPC made top line stuff before they went out of business.

Just for the frell of it, I want to see how it mines SHA256 and Scrypt.

Cudaminer runs out of memory and Bfgminer can't find the GPU. I've not found a definitive answer on whether or not this GPU does CUDA. The 8600M GT does, but the 8600M GS???

bfgminer.exe -S opencl:auto -o stratum+tcp://mzc.pools.triplehexxx.net:3333 -u login.worker -p YoDaPassWord! -I 8 (Of course not real Worker/pass)

cudaminer.exe -H 1 -i 0 -l auto -C 1 -o stratum+tcp://stratum.coinex.pw:9043 -u login -p pass

Changes to make or is it just not possible with this GPU?

Ages ago, when people still used GPU's for bitcoin mining, the AMD family of GPUs was much more capable than the Nvidia ones.  Nowadays using GPUs for BTC mining is over, they consume more electricity than they can generate.  A mobile GPU could achieve something like 20 MH/s (see https://en.bitcoin.it/wiki/Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison)).  Don't waste your time or try killing your laptop...

Cheers

Let me crush your expectations.
That thing is useless even on scrypt. The GT produces 5kh/s, and the GS should produce something like that.
In other words, it is useless.
If you still want to try, try CGminer or SGminer.
