ATI Radeon 7970 OC will not work in Aurora R3
My new ATI Radeon 7970 OC will not work in Aurora R3 nor in my spare Dell machine as previously posted, but does work in a third machine so problem doesn't appear to be with the card. Current card is Nvidia gtx 570. Is there a firmware upgrade that needs to be made or is this card incompatible with this machine. Do I have to use another Nvidia? It has an 875w psu so power shouldn't be the problem. Has anyone else tried the 7970 in an R3?
Thanks in anticipation

bolux,
The R3 PCIe x16 slot is PCI-Express 2.0. What is the requirement for that 3rd party video card? What is the PCI-Express of the system the card works in?

I have tried upgrading my Nvidia gtx 570 with a Gigabyte 7979 OC card in an Aurora R3. Nothing happens,except the fans spin, machine won't even post or beep. I have double checked all connections and to make matters worse, this is the second card I have tried after returning the first, presuming DOA.
Tried in my spare machine and no go either. What are the odds of two faulty cards? Am I missing something. The fans will rotate but nothing else. I have taken all the normal precautions and have done this many times before with no problems. 875 watt psu, 2600k cpu, intel ssd boot 8gbs ram. Any ideas welcome.

Radeon HD 7970 OC 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
I wonder if you hooked up the power leads to the new card correctly.
Your current card uses two 6 pin connectors. The new ATI card uses one 6 pin and one 8 pin connector. The extra two pins are on a separate line associated with the appropriate 6 pin connector.
Just a thought.

AAA737flyer,
Are you thinking the Radeon HD 7970 OC 3GB 384-bit GDDR5 PCI Express 3.0 x16 is backward compatible to our PCI-Express 2.0 slot?

I am under the impression 3.0 is bw compatable to 2.0. May be some set-up issue when installing drivers. Might need to clean out old drivers first etc.

Thanks for responding. The 7970 is a pci-e 3.0, but 3.0 is backwards compatible. That's the spec requirement I belive.

Thanks for the respose. I agree it's not logical for it to work in the 3rd machine but it does, and in a pci-e 2.0 slot. Maybe my Vostro has a different compatibility issue, so it's not helping to isolate the cause in the Aurora.

Thanks for the reply. I think you must be right. I will try one last time today and strip out everything from the machine and see if I can isolate anything.

Yes, I have done that. Thanks for the suggestion though.

Sounds like a BIOS issue ether on the card or the computer. If it was me I would return the card and buy another brand or even a different model. That card is voltage locked now so it's not worth the extra cost.

But it's not really a stock 7970 ... it's tricked out.
Over the years, people have reported various cards not working on the Aurora (and Area-51 I believe). Often, they are OC cards. I remember one was a super-edition nVidia 590-OC that took up 3 slots.
Do you see any options in the BIOS?
Are you sure the machine has the 875w PS installed?
What power supply plugs are you using?
Did you try both slots? (with nothing in the other set)
