Gigabyte Z77X-UD5H PCIE 3.0 Issue

[dragon45801]

Hi guys, I am having issues with my new build and looking for assistance. I am using the Gigabyte Z77X-UD5H on F7 BIOS. The problem is this: If I let my PC sleep or let Windows turn off the monitors, when I move the mouse or turn it back on to resume, my main desktop monitor stays amber and will not come up. If I turn the monitor off and back on it is ok again. I have this issue on a Powercolor HD 7770 and also the same issue on a MSI R7770-2PMD1GD5/OC. The monitor in question is hooked up via HDMI while the 2nd monitor is connected via DVI. I am running Windows 7 Home Premium 64 bit, 8GB G Skill RAM, 2 x Vertex 4 in RAID 0. I have a 730 watt PSU and have tried updating the BIOS, vga driver, et cet. I put in my old vga card, a Radeon HD 6870 pci 2.1 and the issue went away. Any ideas?

HD7xxx got sleep issues. It was noted in the latest beta driver.

So the issue is the vga driver and not the mobo. Thanks man.

I updated to the latest beta driver and still have the issue. Does anyone know if the 7750 is also affected? Is it all 7000 series cards? Thanks

Not saying it will solve your problem, but: F8 is the latest UD5H bios version.

Yea I updated to F8, no change. Pcie 2.1 cards work fine.
