This GPUs and this board is driving me crazy, before i post my problem, let me post my system hardware:
CPU: Intel i7 4770k 8 GB RAM 6 x GPU Sapphire R9 280x BF4 Edition 1 PSU 1300w + 1 PSU 1000w Motherbard: ASRock H81 BTC Pro
This is my problem:
If i plug 1 GPU, no problem, 2nd GPU no problem, 3rd GPU plugged no problem... 4th GPU plugged in and when windows start loading before the desktop GUI shows up, randomly any of the GPU 1st,2nd,3rd or 4th start to spin the FAN at max, the system get freezed and black screen.
Also when i install Catalyst 14.4 or 14.6 beta using only 1 GPU on the board, after driver installation and reboot, i receive no signal image on my monitor when windows GUI loads, i have no clue WTF is going on. If i hit the power button, system turns off so windows does load but the graphics is not showing.
It seems to only work with Catalyst 13.12 and with only 3 GPUs, a 4th GPU is not possible.
I have tried all this possible solutions:
1) Tried on Ubuntu: after Ubuntu install and restart, while Ubuntu loading 1 of the GPU FAN spin out of control system get freezed 2) Windows 7: can run only 3 GPUs with Catalyst 13.12 only, if i install Catalyst 13.11 it does recognize all the GPU with exclmation symbol on 2/6 GPUs, so only 4/6 works 3) Windows 8 and 8.1: Same as #2
When Windows 7, 8 and/or 8.1 load without installing any GPU driver, windows recognize the whole 6 x GPU at device manager but of course, as standard VGA card only, problem arise when i try to install the drivers. This also took me to think the 290x i bought might had the wrong BIOS version, so i made a backup of the original BIOS and tried with different BIOS, same problem, afterall rolledback to original BIOS
Before i got this R9 290x Sapphire, i was running 6 x R9 280x without problem on this same ASRock H81 BTC Pro board, with the exact same PSU and unpowered risers
So my question here is, can any of you have any idea what the f*** is going on cause its been over 48 hours of madness without a solution. Please help
