Hello!

I bought a new nvidia card some months ago, the GTX780 because i mostly use my computer for gaming and I like nvidia for that better (no need to discussion my opinon about that ;) ).

But...

I've also followed the cryptocurrency development since 2011 starting with bitcoin, so i'm also interested in mining. Sadly I missed that train, but now it's entertaining to gamble with the alt-coins.

Im using cudaminer today (many thanks to cbuchner1!) and i'm getting roughly around 620-640KH/s with the latest git-version. Im running Windows 7 x64 with a i7 3930k @ 4.3Ghz, 16GB ram and SSD.

The card is overclocked with ASUS GpuTweak to 1146Mhz/6700Mhz. Pressing it any higher results i BSOD. Temperature is around 80°C and I've tried to raise the PowerTarget and also temperature limit by a few °C.

No, its not GTX 780 Ti. Bought this before Ti was announced.

I use it with the following options:

Do you guys have any hints or ideas if it's possible to squeeze some more out of it?

Oh, and I'm talking about scrypt.

Also, running the auto-tuning seems broken atm, i'm getting a lower KH/s when I let it chose.

TL;DR: Running latest git of cudaminer with GTX780, getting roughly 620-640KH/s, is possible to get it higher?

640 with NVIDIA
are you seriously? maybe some screenshots
even there https://litecoin.info/Mining_Hardware_Comparison (https://litecoin.info/Mining_Hardware_Comparison) there is no such results

640 seems insane with a 780. I'm running a 770 myself and get 270-300kh/s and I thought that was pretty good...

I have a 680 and I am over that I am hitting near 400khs

"I have a potato i grew myself and it's hashing at 900kh/s"

Yeah without any screenshots or explanation this doesn't actually help anyone at all... congratulations though...

I hope you choke on a dick sir.
 You claimed that his speeds on the 780 were not doable I was posted that my shitty old 680s were doing much better then your posts on your cards... that is all I dont need to post a screen shot to validate my config.

I never once claimed it was not doable. I am just genuinely surprised at how he got it hashing so well compared to my own figure and wondering where I could improve. Why don't you calm yourself down?

The latest version of Cudaminer seems to contain a HUGE increase in KHashes. My Zotac GTX570 is hashing away at 245KHash, which I never expected from such a mediocre card.

I'm not complaining :) Still gotta add a couple of decent Radeons though, and get going for real :)

Thanks for the heads up Rit, got another 20 kh/s myself by updating my cudaminer. Looks like another version was released yesterday. It's not a lot but it helps :D

Thanks for your report.
Your hashrate is so much better than that here lol.

Hugely better. And my card is a Zotac, which has the worst performance for that chip in the list. So doubly surprised and happy.

Why all this hate and disbelief? Try the latest version yourselves...

I didn't think a screenshot was relevant, but here it is.

Thanks for the screenshot.
I guess some of us here just surprised about your hashrate, but not really hate lol.

I'm getting about 550 on my 780 GTX since the update to the latest version :)

I Am using the Asus GTX660 and only getting 202khs using the 02-09 build, any ideas on how o get up around to around 400khs?

Try the 12-18-2013 build. It does run hotter, but as long as you keep your fan on high, it's fine. I forgot at one point and my temps ran to 90-95C which led to the card frying itself. After I reballed it, I didn't forget again :) With fan at 85%, my GTX570 is hashing away at approx 245Kh at 65C, which is perfectly acceptable.
