Hello,
I'm trying to setup a Asrock H81 Pro motherboard with 6x Radeon 7990.
When I have 3x 7990 connected system boots normally. When I connect the 4th 7990 the board reports about 50 short beeps. I asked Asrock but they have never heard about 50 short beeps...
It is not a GPU issue as I have tested them individually and it is not a PCIe slot issue. If I have any 3 GPUs it works great, when I connect the 4th, the system won't boot.
Setup:
- Asrock H81 Pro board with Xeon E3, 8GB RAM
- 2 Corsair 1200w PSUs
- 6x Radeon 7990 (3 Gigabyte and 2 XFX)
- 6x Asrock BTC Kit risers
- One PSU is connected to motherboard (including 2x MOLEX) and 2x 7990
- Other PSU is connected to 4x 7990
Thanks a million!
Mike
