Hi everyone, I'm new here. Since I cannot post in the proper topic yet, I'm leaving the question here.

I'm trying to mine Litecoins with my GPU, a 8800gt, but I'm not able to get more than 20 kHash/s. I know that it's an old card and that cudaMiner is young, but from the charts it seems i should get way better results.
I'm using the settings -l 28x3 -i 1 -C 0
L14x3, L26x3 are giving similar results.
Many other configurations just don't work, with cudaMiner crashing. Others are giving impossible hashrates (i.e. 66x2 -> 324 kHash/s) that are not validated by processor. Autotune gives every time different results and often crashes trying L0x0.
Any advice ?
