I've been having problems getting my Z77M-D3H (Rev 1.0) to detect an XFX 7870. Both components are brand new.
I've tested a different GFX card (AMD 5750), which works fine and would appear to indicate the mobo is not faulty. The 7870 was returned to the supplier, who informed me that, according to their tests, the card was operational.
The only way to get an image on screen is to use the on-board graphics (Intel HD Graphics 4000). I've tried updating the bios of the mobo, which was originally an older version, but still no luck. The installation of a beta bios was of no help.
I've replaced the PSU with a new one (650w) and still nothing. I've contacted Gigabyte technical support via email, but have yet to receive a response.
Is anyone able to offer a solution? To say my experience thus far has been frustrating would be an understatement.
