Hi there,
I have some trouble with a newly bought HIS Radeon HD 7970 X2 GHz Edition on an Intel DX79SR Board.
My specs:
Intel I7 3820 @ Default clock
Intel DX79SR Board
16 GB Samsung Green DDR3 (2x 8 GB Kit); Running at 1600 MHz (8-8-8-24)
Adaptec Raid Card 6405E with 2 Samsung HE103SJ 1 TB Drives (RAID 0)
ASUS Xonar D2 PCI Sound Card
Plextor M5 Pro SSD 128 GB
Windows 8 Pro x64
currently:
EVGA Geforce GTX 670 FTW Edition 2 GB
In this configuration the PC runs well, but with a small issue at the boot Screen ("Press F2" etc.) where it hangs up for a while (mainly 10-15 seconds) at code 5A (that occured first after updating the BIOS to vers. 553 from delivery state, which was 537 though) which seems to adhere with the RAID Card because an uninstallation of the Card gets me a fast boot :-).
Passing that point there are no further Problems.
Now starts the fun with the HD 7970...
GTX 670 drivers and card uninstalled, HD 7970 installed... PC started... BIOS screen appeared "Press F2" ect., Screen goes black (and i can't even see RAID BIOS beyond this point) and last post code at the bottom of the right side shows "0_" ... Dunno the meaning of that because the BIOS post on the board itself shows "00" which means everythings ok, I suppose...
Interestingly I can enter the BIOS of the Mainboard where I've seen that the HD7970 starts at 8 GT/s (GTX670 at 2,5 GT/s, powers up in Windows)... Don't know if this relevant...
Funny thing is, I can hear the Windows 8 startup ect. in the background, but the black screen won't refresh and stays at 0_ ...
The problem seems similar to this one http://communities.intel.com/thread/33972 ... but since there comes no further answers I'll start here this new thread... Hope you can forgive me that...
Maybe someone has a clue which is causing this issue...
Many thanks for your support in advance...
Greetings
Edit 04/03/2013:
Did some more testing with an old X38 platform...
My 750 Watt PSU seems to be ok as the HD7970 works as it should... means:
Shows me bios, shows me windows...
Why not on X79??? xD Quite annoying...
But I've found out some more about the DX79SR too...
I have tested the raid card in every else of the x16 Slots above the x1 Slot (which should be running over the CPU and not over the chipset as the x1 slot...) but the PC won't boot up... stucks at POST 26 o. e. and no pictures shows up... not even the BIOS enter screen...
It's curious...
Any explanation?
Or is it just incompatibility?
