Gigabyte 7970 ghz reboot problem

[Aki1973]

Hi, my vga works pefectly when i start the system but every time i reboot the pc windows recognizes it as a standard VGA and there is no way to change the driver from OS. If i turn off (shutdown) the pc and turn it on again everything works fine. Basically i can't reboot and as a workaround i need to turn off the pc (using windows ) and turn it on again (power button on the case). Sometimes after reboot i got artifacts (white vertical strips on display) but not always and that never happened when starting from PC turned off. All components of the pc are brand new (2 weeks) , windows has just been installed, i didn't overclock card or cpu. The Bios of motherboard is the newest version (2.70). I tried with different connection cable (dvi, hdmi ecc.) having same results. I can't try the VGA on another desktop (i don't have other desktop PC available in which the card could fit)to check if it's causing the same problem. In Bios the primary connection is PCI-E and the card is installed in PCI E number 2 of the motherboard, i didn't use lucid virtu software (IGP and GPU working together) even if my motherboard has an igp chipset on motherboard (HD4000).

My rig is:

Motherboard Asrock Z77 Extreme 6 socket 1155, PSU Antec HCG-620M 620W 80+ Bronze, 8 gb RAM DDR3 Corsair Vengeance Blue Low Profile CML8GX3M2A1600C9B 1600MHz 8GB (2x4GB) CL9, CPU Intel Core i5-3570k, hd SSD Samsung 840 UltraSlim Series 128GB Pro, Internal Sata Hard Disk Western Digital Red 2TB, asus xonar dx, wireless pci tplink

How can i fix ? Thanks in advance.

Sorry for my bad English

go to this page

and install catalyst 13.4 use it to uninstall all amd drivers then install catalyst 13.4


http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_win8-64.aspx



note this is for windows 7 and windows 8 64 bit. if this does not work try the beta version on the same page


also make sure this below has been done. it is on the same page

AMD Catalyst Control Center requires Microsoft .NET4 Framework. Windows Vista and Windows 7 users may need to install the Microsoft .NET4 Framework as a prerequisite to use Catalyst Control Center.

I think what's happening here is that your motherboard doesn't disable the iGPU. Some motherboards do, and some don't - but those that don't will show a "standard VGA graphics adapter" in the device manager in addition to your primary (pci express) GPU, ie, they will show two graphics adapters even if you have only one. If this is the case (2 graphics adapters in device manager), what you do is right click the standard VGA adapter in device manager and disable it. Do not uninstall it - disable it. Then reboot. At this point, the iGPU will be disabled and you won't get conflicts on subsequent reboots.

I have exactly the same problems as you.

My motherboard is an Asus P8Z77-V and my PSU is a Corsair HX 1050W. I also have a Asus Xonar DX.

When the driver reverts to "Standard VGA Graphics Adapter" if I check the device id of the GPU it is 1002:6790 instead of 1002:6798 as it should be. That's why it reverts in my case, not the iGPU being active.

Have you found a solution?

Not yet. Still fighting with it.
Think that vga is defective in some way, i even flashed original bios on both switch, modded inf file of ati driver (partially successfull cause i succeed installing driver but at reboot the driver stops working), changed pci e slot, formatted, updated bios of mb. The performance of the card when recognized in win are good .. this is so strange. I don't understand how a reboot can act on reading wrong data eeprom from vga (i suppose that device id is determined by a reading of the eeprom). I should try to test the card on another rig to check if could be an uncompatibility between mb and vga. Btw even my vga change device id after rebooting (1002 6790).Any ideas to solve or test something else?

Exactly the same issue, I have a 5 year old PC with Windows 7 which with a 6970 never had this issue but since installing the 7970 Ghz it mostly boots up ok but occasionally is not detected. I recently purchased a new PC, so different motherboard and BIOS etc and Windows 8 and same things happens, old 6970 is fine, 7970 Ghz occasionally not detected.
Leads me to believe fault is with card not motherboard, bios or OS etc.
Given card work flawlessly otherwise I am putting up with it.
