Refer to my thread here: https://bitcointalk.org/index.php?topic=36182.0;topicseen

to sum up quickly

My Rig-
Memory: 2gb Ram
CPU: Core I7 960
Motherboard:Gigabyte G1 Assassin
HDD: 500gb
GPU: 4x ATI Radeon 6990HD (HiS)(watercooled)
Power supply: 2 x 1200W Corsair
OS: Win7 x64
Driver: ATI catalyst 11.7 w/ SDK 2.5
Frontend: GUIminer

No problem with the GPUS, they all work, they all show, they're all functioning.

The problem is more in the fact that I can't run 8 miners at a time. I think this may be a RAM issue, but pretty sure it isn't as only 1.4gb RAM is taken up at most (task manager).

I've tried a few combinations - 8gpus, 7gpus + 1cpu Miner, 7 poclbm + 1 pheonix

All that needs to be noted is that, no matter what order the miners are started, the last miner to be started will hang with "miner started." It will never connect and start mining. If the last miner happens to be openCL, I will get a "poclbm.exe has stopped responding" windows message.

I did want to try Ubuntu, but it seems very tricky starting everything up with all those sudo commands. Is this a limitation within "conhost" or Guiminer?

It could be a driver issue, bit I'm curious to see how this works out for you.

Setting up a mining rig to use Ubuntu isn't that complicated. If you want to mine with an OS that uses the Linux kernal and don't want to deal with a-lot of package installation try Linuxcoin.

To live is the rarest thing in the world, most people simply exist.

Try cgminer, it'lll feed your 8 GPU cores from one process without problems.

cgminer for the win, windows version even includes a how to make a bootable usb linux miner.
personally i install to harddrive, but i copy/paste the commands from the guide - makes it very easy Smiley

on my 4 card linux boxes i shh in and they all run cgminer in screen

on my windows miners i use cgminer and teamviwer - no miner has a head Smiley

Probably should have mentioned that I ended up getting all 8 cores to work. Not too sure what exactly it was, but we did have a faulty power supply (one of the fan ball-bearings was out = low - high pitch whistling sound), and after replacing that and removing the dummy plugs, all 8 cores worked fine. Not too sure what was the exact problem, but haven't fiddled around with it since just in case the problem happens again.

I'll probably try out cgminer just to see how that works out.
