Updated on rig to 12.1 and BSOD with 5 5850's, dropped back to 11.12 and fine also
THANKS! Been killing myself trying to get my f*king $260 mobo to run more than 4 GPUs. Not much of a Linux person, but I even tried perusing that without luck so far (different issue though, Diablo wouldn't start up, but I believe it was because I tried using an old AMD SDK)
Will try as soon as I get off work and let you know if that works for me jjshabadoo; but from what I have heard this was a driver issue for Windows, so this makes sense to me. I would have thought that if it was fixed in 11.12, that it would have been fixed moving forward, but then again, it is the AMD dev team making these drivers
Whats you address portron? I'll send a couple coins your way if I can get this working. Sorry you were late to the party bangra, I don't have a lot of MH/s or I'd send you some BTC too
Also, possibly related to the 12.1 drivers, Windows would not even stay booted without BSODing until I had the first PCIE-x16 populated with a 16X graphics card (1x risers don't work for me in 16x slots, although that's probly my mobo)
Worked for me! Thanks portron! What's your wallet address? I'll send a couple BTC your way for the help.
jjshabadoo, to document my process: I installed Driver Sweeper from Tech Powerup, express uninstalled all ATI drivers, rebooted in safe mode, ran driver sweeper, cleaned AMD display drivers, rebooted in normal mode, installed 11.12 drivers, and 2.5 SDK, then installed 2 more GPUs for a total of 6 and Windows started hashing!
Note driversweeper will delete any drivers that were extracted into C:/AMD or C:/ATI, so you will need the download package for 11.12 and 2.5 SDK
BTW jjshabadoo, I am using the same motherboard as you are I believe, as per your other thread; I have the P8P67 WS Platinum, 1503 BIOS. You should be able to use up to 7 video cards (8 GPUs max) using my instructions above.
