HD7970 not POST'ing

[pio]

I remember this being an issue for people with LGA 1155 back in the day originally, but I don't recall hearing about people having this problem with AMD boards.

Anybody know where I can start looking to fix this problem of my ASRock 890FX Deluxe5 (BIOS 2.00) not POST'ing with a Gigabyte Windforce HD7970 Rev 2.1?  The board works fine, attempts to boot up just fine with a GeForce GT310 installed.  The card works fine, I just pulled it a few days ago from my 990FX / FX 8350 rig.

If the card is installed alone in the 890FX board, I just get an "error code 97" on the little display on the bottom of the board, and no picture at all, and no POST beep.

It's got to be a BIOS issue, but there's no later BIOS's for the board that address anything like this.  And I can't seem to find any GOOD results for the Windforce v2.1 being flashed to a different BIOS either.

So far, here's what I've done.....ALMOST successfully.

 

1)  Flashed the 7970 to the older F41 BIOS available directly from Gigabyte.  The newer F3 BIOS (and leaked F8 BIOS) didn't want to POST in the 890FX.
2)  The above F41 BIOS made the card unstable with 3D, BUT....it works in the 890FX.
3)  Flashed the 890FX from BIOS 2.00 to 2.01 beta.  Seems to work?  Hasn't been very stable since the flash, but could be the GPU BIOS.
4)  Switched 7970 BIOS switch to #2 once 890FX was flashed.  It POST'ed.  Never did get it to boot again.
Note:  After the 890FX BIOS flash, the BIOS was then UEFI instead of old school.  Might be the bootup issue?
5)  I'm now installing Win10 (again) using UEFI.  F2 (stock) BIOS on the 7970 and latest beta 2.01 BIOS on the board.

 

Seems to be working now.  The card is 3D stable in the 990FX Sabertooth again using stock F2 BIOS on the card, whereas it wasn't on the F41 there either.  It POST'd and installed Windows on the 890FX now.  Maybe, just maybe it'll work???

EDIT:  It's working.  The 890FX now has the 7970 installed, 3D is working.  So yeah, needed to update the motherboard's BIOS to a beta.  Kind of a PITA since the 7970 is the card I bought for the rig.  Stress testing the OC's now.
