Just an update. I have all my cards running now and am getting around 2 Ghash/s on LinuxCoin v2.0a with Poclbm Stably for 2 days now
OC'd with AMDOverdriveCtrl
I have 2 5970 running @ 850, 300 getting around 2x(350+350) Mhash/s (75 degree Celsius)
A red Sapphire 5850 getting only 280 Mhash/s @ 765, 300 (Max OC 775 -.- 75 degree Celsius)
A blue Sapphire 5850 getting 350 Mhash/s @ 900, 300 (Max, 62 degree Celsius)
I have had problems with my working computer as the MOBO and HDD died on me, just got sort of a more stable one up and running.
A little deviation from my initial plan since I don't know how to hook up 2 PSU together, I ended up with a GD70 (5 slots, 3 used) on 850W PSU and my 'new' computer is M4A88TD-V Evo/USB3 (2 slots 1 used) on another 850W PSU.
I'd like to optimized the rigs more in terms of hardware and at the same time the overclocking, OS used, miner (kernel?) and such. However, I'm not sure where to head to now.
If you have any advice please do let me know. The rigs are running on USB, I've read another thread recently on using Ubuntu, Pheonix and proper OC'ing. however these are not my forte and I'd like some help in direction right now. (especially on the 5850 which seems to have a lot of potential for OC'in right now)
I'm also trying to source for investment to build another rig. I'd like to ask if any knows running 4/5x5850 what kind of Power Supply would I need. And I have been struggling with the 100% CPU usage on Windows (Poclbm) problem at the same time. Apparently this hasn't been solved it.
Please suggest some MOBO that might drop the cost, I'm intending to get more rigs and now cost has become a focus on my list of todo.
I intend to get another rig up with 5850.
