Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]

I can check my 780 on pci 3 x16 if you guys want those results

That would help tremendously. What kind of risers do you have? Can you try a 16x to 16x riser or even a 1x to 16x in that PCI-E 3.0 versus the card being put into the slot directly? Thanks.

I missed the riser part sorry. Would test it but it means ripping my water cooler apart :-(

Ah, no worries. Would still be curious if 3.0 slots yield any benefit versus 2.0 slots for cudaminer if there was any way you had a means of doing that without messing up the water cooling.

While I dont have any risers laying around my motherboard has PCI-E 2.0 x16 slot running at x2 and a heavily overclocked GTX 780.
Here is my config for my GTX 780: cudaminer.exe -q -i 0 -m 0 -H 2 -l T12x24
PCI-E 3.0 x16: ~715Khash/s with a bus usage of ~13%
PCI-E 2.0 x16(x2): ~685Khash/s with a bus usage of ~40-50% (I forgot the exact number)

If you have any more questions feel free to ask.

I tried your launch config on my 780's, but I'm only getting 40Kh/s on scrypt.

That's odd, even a stock GTX 780 should get ~600Kh/s. Im sure everyone here would agree that -q -i 0 -m 0 -H 2 -l T12x24 is the most optimal scrypt launch config for a GTX 780. Make sure you have SLI disabled when your mining. The last time I checked, sometime around December, cudaminer doesnt work when SLI is enabled.
