4 x 7990 trouble
#1
Hello, I'm having troubles with my motherboard when adding the fourth hd 7990.
I'm using an old asus P6T7 WS Supercomputing with 7 PCI-E slots and all goes fine with three 7990; when I add the fourth the computer stay black.
It should not be a power trouble because i'm using two different PSU (1kw + 1,5kw), I also update the BIOS to the latest release.
It is not even a trouble of the fourth 7990, I've two more and changing the order do nothing.
Do you guys have any idea?
Also, do anyone know a working motherboard in a 4x7990 configuration? (tyan rack apart).
Regards,
Raist
