GPU mining with GTX 570 and need help with hash rate (CGMiner)

[Caiapfas]

When I first stated using the GTX 570 I was getting 33kh/s, but with the below command I am showing 85 kh/s. On the litecoin hardware comparison chart it says it can get 140 kh/s. Can anyone help me get it there. Increasing the intensity causes hardware errors.


Few side questions:

• Why in Coinotron does it show like 35 kh/s?
  Why does it drop from the worker in coinotron and reconnect over and over , over a period of hours?

setx GPU_MAX_ALLOC_PERCENT 100
cgminer --scrypt -o stratum+tcp://coinotron.com:3334 -u Caiapfas.gpu -p 123456 --thread-concurrency 5000 --gpu-threads 2 --intensity 13 -w 256 --gpu-engine 1080 --gpu-memclock 1500 --gpu-powertune 20 --temp-target 72 --temp-overheat 85 --temp-cutoff 90 --scan-time 1 --queue 0 --no-submit-stale --lookup-gap 2 --expiry 1

notice how it says 'cudaminer' in the litecoin hardware comp page and not 'cgminer'.  That's your issue.

Cudaminer does 2x to 4x more faster than CGminer or Reaper for NVidia. Still not enough to make it worth mining with NVidia cards. You could probably trade with someone that's not into mining and is a gamer for a AMD card(s), just my advice if your trying to maximize your profits.

I used to get about 240 kh/s with a GTX570 and cudaminer.

Can you send me the command line you used or any part you remember for that, PLEASEEE thanks

A HD 6970 can do a little more than double of that, 500 kh/s. That's just an example of how AMD is king in GPU mining.

Here's what I use for my GTX570.  I get just over 250KH/s.

cudaminer -q -i0 -s2 -C1 -l F15x16 -o stratum+tcp://middlecoin.com:3333 -O 1tbMrCLS1EBCSw8t676kykhV9gcWprxPP:adsf

cudaminer.exe -H 1 -i 0 -l F15x16 -C 1 -o stratum+tcp://xxxxx.com:3333 -O user.worker:password

even without that command I'm getting 279.6 KH/s - cudaminer is great app. I'll have to watch it and see if its stable 279.6 KH/s.

I'm getting a 280x you think cudaminer is the best to run that too?

No, for a 280x, you will want to use cgminer 3.7.2 (or earlier) and '--scrypt' in the command line.

[Caiapfas]

do you happen to have the best command line and flags to run it (280x) with best hash?
if i put both cards in same system how can i make cuda run the 570 and cgminer run the 280x?
thanks
