It appears your board (2AC8) is terrible about upgrades.

Lots of good reading here:

I think what needs to happen is a bios update for your board to make other cards compatible.

The link posted to the documentation is broken on their page, here is a fixed link:

The only BIOS update listed by HP (when I punched in the model number of the rig on their BIOS/Driver update search engine):

M3970AM-HP Motherboard BIOS Update

7.16 Rev. A 3.1 MB Nov 23, 2012

Doesn't look very promising. I am not even sure that qualifies as a "BIOS update", when we talk about updating the BIOS. I mean 2012 ?? I checked the changelog in that BIOS update and it looks very underwhelming...I'm thinking this is a no-go but I can't prove it. I am thinking if I do this, I have to be prepared to pull a new rig out and approach this swap eyes-wide-open.

Still researching other people who have gone ahead and attempted it on this mobo/OS looking for a sign.
