Hey guys, playing around with an old pc i found in the basement.
Trying to GPU mine altcoins with an Nvidea GeForce 8600 GTS on an 2x2,4 system.

Using cudaminer and this settings:
cudaminer.exe -i 0 -c 2 -l 32x4 -m 1 -o stratumblablablaport -o user:password


Getting the error of the title like 50% of the time. And besides that a way to high hashrate in my opinion of 200khas+.

<- nearly no experience with GPU mining, so tried alot on the settings but nothing helped.


Any ideas?
