Just blogging this in case to avoid anyone else having the same hair pulling experience that I’ve had for the day.
I was recently asked by a friend to put together a machine for stock trading. The main feature was that the computer had to support 8 displays (for tracking market charts and news etc).
In the end we went with an ASUS P8H67-V motherboard as it supported PCI-Express and 3 standard PCI slots.
The Graphics cards we got were:
- 1x Radeon HD6450 (PCI-E)
- 3x Radeon HD5450 (PCI)
Anyway we plugged in the PCI-E card and everything worked fine. Howver, we then plugged in the PCI card and the machine refused to post, displaying nothing on the monitor. Unplugged the PCI-E card so that only the PCI was left, and still nothing.
After a lot of fluffing around, I got the latest BIOS update (v0712) from ASUS (http://www.asus.com.au/Motherboards/Intel_Socket_1155/P8H67V/#download) and applied it using their BIOS flash utility.
Happy to report now that everything is working fine.
Short Version: In order to run PCI graphics cards on the ASUS P8H67-V motherboard you need to flash the BIOS to the latest version.
