I have those two cards in one rig here is my bat file

setx GPU_MAX_ALLOC_PERCENT 100
cgminer.exe --gpu-platform 0 --scrypt -o stratum+tcp://stratum.give-me-ltc.com:3333 -u username -p password -I 20,19 --lookup-gap 2,2 --thread-concurrency 20480,10192 --worksize 256,256 --shaders 1792 --gpu-engine 1110,1110 --gpu-memclock 1500,1440 --expiry 1 --queue 0 --auto-fan --temp-target 82,79 --temp-hysteresis 2

with this setup I get 1050kh/s on average

btw why you typed in your settings username and password two times??

Thanks for the config, I'll have to try it out. I currently have both of them running together for 950KH/s. May I ask which card is the 7850? It's the one with intensity as 19, correct?

Thanks so much for the config! As for the username and password x2 thing, I thought it was needed for some reason, not sure why though. Huh

both cards are sapphire. 7850 runs at intensity 19 it gets very few hw but it's not significant.
7850 -around 384kh/s
7950 -around 665kh/s

"Raven's Cry"

and i keep missing the point of miners adding the --shaders option.

YOU DONT NEED IT, YOU USE --TREAD CONCURRENCY which overrides anything you put into --shaders.. Grin

Hey everyone, I'm using CGMiner to try and get both my 7850 and 7950 to mine together, with different settings.

Here is my config this far:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS
cgminer.exe --scrypt -o stratum+tcp://multipool.in:3334 -u USERNAME,USERNAME -p PASSWORD,PASSWORD -d 0 -d 1 --intensity 17,18 -g 1,1 --thread-concurrency 8192,17000 -w 384,384 --lookup-gap 2,2

Do you know what I'm doing wrong here? When I start the batch CGMiner sets the allocation to 100% then closes right away. Any help will be much appreciated!

drop the worksize down to 256

You are trying to do way too much in that line and getting it all jumbled together.

Just launch cgminer with your bat and then edit the cgminer.conf file, it's easier than doing it this way for multiple GPU settings
