only getting 52khs on Litecoin mining with a Nvidia GTX670 I want to give mining a try with the current video card i have. I know its not good for mining but its a start. I use cgminer and link it with WeMineLTC. For some reason I only get 52 KHash/s. I saw my GPU is at 100% and it isn't overclocked. What should be the reason I only get this low hash per second? I saw on this page it should be around 112 000 KHash/s.

This is my bat file

cgminer.exe --scrypt -o stratum+tcp://global.wemineltc.com:3335 -u workIt -p totallymypsw -I 13
You shoud instead use cudaminer for this. I use the same card and I have a mining rate of 150khash.

The reason why you get a low mining rate is because Nvidia cards use CUDA cores to do most of their calculation and most of the miners do not use them since the best graphic cards for mining are AMD cards (and they do not have CUDA cores).

I dont know where you saw that 112 000 Khash/s (mostly because you forgot to give the link) but I doubt that a single card could do that with litecoins (but its possible with Bitcoins).
