450watts psu, phenom II, 3gb ram, asus m4a78LT-m LE, HD3000 onboard running Win7HP.
PC boots up fine with HD5670 but display is only on onboard graphics. HD5670 has been tested on four separate configurations and it runs fine. I have checked all the bios options but still i could not get any display on HD5670. It shows blank screen. There are no options to turn off the onboard or the ati crossfire. What could be the problem?
Hello and welcome to the forums
Have you installed the latest VGA drivers ?
Also,there should be an option in the BIOS for setting the PCI-E priority,make sure its set to PCI-E(not onboard).
BTW,since you are using one 5670,there isn't an option for disabling Crossfire,so don't bother with that.
m4a78LT-M LE runs AMI bios v02.61, 0704
Is there a bios update available?
If yes, then how can i safely update the bios?
Bios shows EZ flash 2 in tools menu. Theres a windows bios utility also supplied in mobo dvd.
cpu : phenom II x2 (runs 4 cores with core unlocker)
ram: DDR3 1333
IDE harddisk pata
I do not need hybrid crossfire so that the onboard graphics gets switched off completely and dont mess with the HD5670 on X16.
Please suggest a ASUS motherboard without the hybrid CFX.
