Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
I'm mining MaxCoin with 1GH.com using Cudaminer, and I have an NVIDIA Quadro 4000 graphics card that I'm using. Oh, and I'm on a windows 7, 64 bit computer. Things seem to be working, but I want to be sure that I'm not potentially burning up my graphics card. I originally set my connection string set to:
cudaminer.exe -H 1 -l F512x16 -a keccak -o stratum+tcp://maxpool.1gh.com:17333/ -u account -p password
Later I replaced F512x16 to F256x16 to see if it would run cooler. The hash rate changed to about 27750 khash/s, but the temperature stayed exactly the same. Usage changed from 97% to 95%.
Oh, one thing, I get an 'error message when it first starts up that says "Given launch config 'F256x16' requires too much memory. But then it goes ahead and starts running anyway with those parameters. I do get that message with almost every configuration I've tried. It only disappeared when I set it to F16x16, which was depressingly slooooooowwwwwwwwww.

Can someone who understands this stuff tell me if I'm within a good range to maintain optimal performance while keeping my graphics card in good shape??? Or am I risking wearing it out? Is there a more appropriate setting for my graphics card that I could be certain would not overtax it, but still maintain a good hash rate?
Also, I've been letting the program run pretty consistently all day (probably over 16 hours I think), and I've only earned 0.16 MAX. That seems kind of low, doesn't it?

Quadro 4000 based on chip GF100GL : 2 GB GDDR5, CUDA Cores 256, Shader Model 5.0, based on the GeForce 400 Series Fermi architecture.
"The GF100 cards provide Compute Capability 2.0, while the GF104/106/108 cards provide Compute Capability 2.1."
you can try "-H 2 -C 2 -m 1 -l F1536x16 -L 256 -i 0" , if still memory error at launch lower to -l F1024x16 but keep -L 256
but dont expect too much from 2.0 compute card
