Mining-Will a 280x and 270x crossfire together for mining?

[kinoblemeister]

Hi guys,

As above, will they work together even though they are different cards? My belief is they will but kh/s will be matched to the lower card?

Mu 280x currently runs around 700kh, will this be brought down if I add a 270x? Or would it be worth it overall?

Also is this okay to run on a Corsair 750w PSU?

Ta!

You dont enable Crossfire for mining so it does not matter.

PSU should be strong enough yeah.

Hi 8pack!

Thanks for replying.

I use a cgminer scrypt right now, how would i run the second card in the .bat file??

That's right, each GPU is an individual miner.

So you set up the miners in your pool account, IE:

username.1
username.2

And then set each GPU to mine the different pool accounts in the Script or GUIminer.

Ah okay, so set up a new worker (I only have 2) and in the SAME scrypt just use that new worker and password etc?

Also do I have to use the same make as my 280x (msi) with my 270x?

Yes, I think so. I use a GUIminer so I can select the GPU from a GUI Drop Down.

As I can run multiple miners from the same GUI I would have thought it would be the same with the cgminer as all the GUIminer is is a cgminer with a graphical interface, at the back end it does exactly the same thing. (writes the scripts for you)

so kinda like this:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://lite.wemineltc.com:3334 -u user.2 -p 1234 -I 13 -g 2 -w 256 --thread-concurrency 8193

cgminer --scrypt -o stratum+tcp://lite.wemineltc.com:3334 -u user.3 -p 1234 -I 13 -g 2 -w 256 --thread-concurrency 8193

Try it, I don't know, why do you think I use GUIminers if it doesn't work ask here http://forums.overclockers.co.uk/forumdisplay.php?f=158
