Hi all,
I have a few different types of mining going, mostly for fun, not really expecting much profit with the hardware I have. One of the machines has an NVidia GeForce 8400 GS gpu.
After finally getting cudaminer installed and the drivers going, I have been experimenting with settings to see what kind of hash rates I can get.
I got fairly excited when I saw: [2013-12-18 07:31:48] GPU #0: GeForce 8400 GS, 1003520 hashes, 122.66 khash/s
I am getting occasional errors: [2013-12-18 07:32:13] GPU #0: GeForce 8400 GS result does not validate on CPU (i=62, s=1)!
But in general, it runs right around 120-130 khash/s.
The problem is that I never see a block get accepted. I am mining a litecoin pool and it looks like cuda is using the scrypt algo.
Here is my current command line and what it shows on startup:
cudaminer -l L16x4 -o stratum+tcp://usa.wemineltc.com:3334 -u jplangan.cuda -p x -H 1 -i 0

Any suggestions? Thanks in advance!
