Let me guess, you're in a hotel for the "free" electricity, and you hide a truckload of miners in the closet.

BTW:

Overclocking my 570 from the stock 770 MHz Core Clock to 900 MHz (a 17% increase in the Core Clock and a corresponding increase in the linked Shader Clock), which my card can do when slightly overvolted (1.0 v -> 1.038 v) raises the rate from about 230 kH/s to 266 kH/s (a 14% increase in hash rate). It does not appear that we are very memory speed bound.

I am leaving my card at stock frequency though, because I want desktop stability and do not want to overheat my card any more than necessary with the torture it is already getting from mining. 670s don't grow on trees you know .

I don't see how you guys can get any gains with GT5xx cards. If I enable any -C option with my 560Ti, I lose a third in kHash throughput. MEH!

In case any one can use this info:

Two Msi 660Ti (stock OC)
cudaminer 2013.04.09

autotune always finds 147x2 best, so I set it myself:
cudaminer --no-autotune -l 147x2 --device 0 -t 1 -o localhost:8332 -O username:password
cudaminer --no-autotune -l 147x2 --device 1 -t 1 -o localhost:8332 -O username:password

One mines 24x7, other - only when I don't mind the desktop lag
I get around 128-135kH/s from each, which is about 20 more than anything else. Only problem is cudaminer crashes nvidia driver everytime I quit it.

P.s. I mine on coinotron and use a proxy with this:
mining_proxy -pa scrypt -o coinotron.com -p 3334
It took me ages to find one that works for LTC here: https://github.com/CryptoManiac/stratum-mining-proxy
Maybe now someone will google this and be happy

I would fiddle with the -m 1 command with autotuning

I did this and was able to get another 10K out of my card

First off, absolutely great job with this cudaminer development!

For interest sake, these are some of the results i have seen:
GPU: gtx 460 (OC to 920Mhz with MSI AfterBurner)

GUIMiner: ~65kh/s
Cudaminer 9-4-2013 (56x2): ~95kh/s
Cudaminer 10-4-2013 (56x2): ~124kh/s
Cudaminer 14-4-2013 (14x8): ~127-133kh/s

Virtually a 100% improvement is truly incredible.

One thing I have noticed though, and would just like to check whether its normal or not, is that with 14-4-2013 my gpu seems to run at anywhere between 92 - 100%, giving me an average speed of ~127kh/s (changing between interactive modes does not change this). However, if i open, say, my browser while mining, then my gpu usage is consistently at 100%. This seems expected, but what is not expected is that my hash rate all of a sudden jumps to ~133kh/s!

Is this normal behaviour? Is cudaminer running faster because the gpu is being forced to run at max with the browser open? If so, would it not make sense to simply make cudaminer consistently use 100% of the gpu (assuming of course that my PC is not just crazy and likes to do wierd things )

I only ask because i have not yet anyone else report this, and maybe I am seeing something that does not matter.

Thanks again, for all the amazing work.

p.s.
join.me, isnt it paid service?

if you arrange teamviewer/vnc I can take a look)

'which one?

use cudaminer

it works quite weill for nvidia cards

Oh, If the pool isnt responding, like this; , ctrl-c isnt working.

Hmmmn,

tried cudaminner on another clean win8 pc , and it wont run complaining about some msvcp100.dll which is missing. visual c++ 2010 runtimes are installed.

the file is where it should be windows\system32

When i copy the msvcp100.dll to the directory of cudaminer: it still wont start giving me windows error code 0xc000007b.

on a clean pc that is VERY strange in the least
