Title: Help needed on board GPU and external GPU
Post by: crazyearner on November 15, 2012, 02:41:19 AM
I am currently using cgminer and wanted to know if it is possible to make a .bat file to mine with my external gpu at the same time as mining with my onboard gpu.

Does anyone know how to make a configuration for mining with both at the same time? Or can this not be done.

By onboard and external, you mean integrated and dedicated? CGMiner should mine on any GPUs you have, unless you specify otherwise.

Thats what I mean yes. But how would I set my .bat file to do them both tho as I only know how to set up for one.

cgminer -o pool -u username -p xxx --shaders 1600 --intensity 14 --worksize 256 -g 1 --auto-gpu --gpu-memclock 310

If you use one variable, it adds that variable to all your cards. If you want to specify different values for different cards, you add commas between your values.

Try this:
cgminer -o pool -u username -p xxx -I 7,9 -w 256 --auto-gpu --gpu-memclock 310,305

--shaders only works when you're mining litecoin, but if you're doing that, then you don't want your mem that low. I: higher than 9 can sometime cause high CPU usage, and you won't get any faster results, again, unless you're mining litecoin. And lastly, -g 1 is only really useful if you're using p2pool, or dynamic intensity.

Could you clarify what you mean by "External" and "Onboard" GPU?  Many motherboards and the new CPU's will disable the onboard GPU if it recognizes a discrete graphics card in the PCI Express slot(s).

well its not rocket science, External been a card that you put in to your system and not onboard.
which motherboard and what cards have you got
some motherboard will disable the onboard GPU if a PEG is used
