lol ok


You'll get HW Errors if your thread concurrency is low when using > 13 Intensity.

Try the following 2 (Without guiminer, just use bat files).


Low intensity for browsing web and stuff while mining:

-w 256 -I 13 --gpu-threads 2 --thread-concurrency 8192 --shaders 2048 --lookup-gap 2

(Use 1792 shaders for 7950, 2048 for 7970).

Anything above -I 13 will cause a laggy mouse etc on full themed windows.


High intensity, just add the following as the rest of the settings will be determined by cgminer

-I 20


Keep one thing in mind, guiminer likes to either report wrong information sometimes or doesn't properly cap out your cards potential, it often bugs after stop/starting a few times.


So make a full bat file

cgminer.exe --scrypt -u x.1 -p x -o host:port -w 256 -I 13 --gpu-threads 2 --thread-concurrency 8192 --shaders 2048 --lookup-gap 2


Right now with 1100core/900mem I get 595KH/s on a 7950 with:
-w 256 -I 13 --gpu-threads 2 --thread-concurrency 8192 --shaders 1792 --lookup-gap 2
(This allows me to browse, play league, etc etc).

And with 1105core/900mem aswell I get 675-680KH/s on a 7950 with just:
-I 20


For some reason, 900mem gives me much better results than 1000, 1250, 1575, 1750 etc.

The - g 2 I- 13 and -8192 thread currency should be an old trick for getting a good setting for browsing,as you telling to CGMiner you have 2 vga's (-g parameter means number of cards) and that seem's to double the KH's.

Anyhow you can't use it above I-13 because you will get HW Errors.

so in gui miner, if we have 4 cards we should set gpu threads to 4?

Nah, automatically sets each gpu to 2 threads when the value is 2.

Anyone knows how can i dump coins at markets for USD? I was thinking of using btc-e but im not reading very nice things about it.

Im thinking at LTC -> BTC (BTC-E) - BTC -> USD (MtGox,Coinbase,BitStamp).

These are the settings that won't yield good performamce on both cards. My original post is a page or two back.
