I bought a few more of these RX cards and since I exceed more than 4 GPUs in Windows 7, I had to use that 7GPU Mod Registry hack, however it doesn't seem to work with the newest drivers 16.9.2
It worked perfectly fine running 6 - R9 280X on version 15.7.
The cards are recognized in Windows Drivers however, I can't get more than 5 GPUs to run in one system. Whats everyone been doing?
Install Win 10.
I was stuck at 5 cards, last one was Code 43
EDIT: with 16.9.2 and the last one 16.10.x
Yeah I had no choice but to install Windows 10. Pain in the ass really since the CPU is a Sempron 145. Would of done Ubuntu but since there is no Wattman/Watttol would have to flash to undervolt.
