Graphics Card not recognised by motherboard

Hi,

Having a very strange issue regarding a mother board and graphics card not getting along!

The motherboard will recognise other graphics cards, just not the one I need to use (listed below)

Doesn't appear to showing in device manager - I tested a different graphics card (Saphire 7770) and that works perfectly.

Downloaded AMD's autodetect software and that can't find it either.


I really have no idea what the issue could be since the card in question works in another machine perfectly.


Any ideas / help would be greatly appreciated.



Cheers,
Andrew

Motherboard - Asus M5A99X EVO R2.0... P/N:  90-MIBJI0-G0EAY0VZ
Processor - AMD FX Black edition... P/N:   FD4300WMHKBOX
Graphics Card - Club 13 Series Radeon 7970 XT2... P/N:   CGAX-7977S13

Two things off the top of my head:
- not enough power is being delivered to the card by the power supply.
- the ASUS PCI-e 2.0 slot does not like the PCI-e 3.0 video card.

Do you have the latest BIOS installed on the motherboard?

Thanks,
The PSU is a 850W, there are 2 x 6-pin PCI power connectors connected to the card

I've just upgraded the BIOS to the latest version which hasnt helped.

I have had a Sapphire HD7770 working in the same slot and thats a PVI v3.0 too, so i'm not sure about whether that would be an issue.

I'm not sure what else to try.

I think it should actually have 1 x 6 pin and 1 x 6+2 pin power connected which isn't on this psu so just about to try a different psu.

OK. While you do that, I'm going to see why my test rig is all the sudden being colicky.  : /

As you already noted, you've connected the wrong auxiliary power to the card.

It requires a 6-pin and an 8-pin connection.   The 8-pin PCIe connectors provide double the power that a 6-pin does (150w vs. 75w) ... so it seems very likely that's your problem.

Nice card ... but definitely very power-hungry !!  (needs 225w more than the PCIe bus can provide !!)
