Really low 7950 score - windows 8.1 bug?

I'm trying to help a friend of mine who recently upgraded his CPU/motherboard.

He upgraded from a Core2 Duo to a 4790k and z97 board, reused the same 280X graphics card (rebranded 7950 from what I can gather) and is getting extremely low 3dmark scores and fps in games.

Here's the 3DMark score:

http://www.3dmark.com/3dm/5576632

Something is clearly wrong - as I don't have physical access to his PC it's hard to diagnose - gone through the normal checklist with him - He's tried two good quality power supplies, using two separate 6 pin connectors with both of them. He also tried reseating the card.

The card goes to 100% load during Firestrike, temperatures are perfectly fine reaching 75dc at the highest.

He's also tried a few different drivers.

I'm wondering if there is some issue with 280x's and windows 8.1? Or it could just be a faulty card. I advised him to try Windows 7 before sending it back for RMA, though wanted to check here just incase this is some common windows 8.1 problem.

Many thanks.
 
Shouldn't be issue from 8.1, I'm on that and have a slightly higher bench than your score with the 7950.

Have they installed latest dx and updated?
Have they tried another benchmark to compare those results? Valley? etc (If they're all clobbered, then likely a hardware issue during transfer and might need replacing if unlucky)
 
I'm confused - the 280X was the 7970 was it not? So if he's got a 280X it shouldn't be showing up as a 7950 in the first place.

That score really is woeful though, barely better than my old 5750 managed! :o
 
See if the performance of the card is up to scratch, then see if the card performs fine in something like Furmark at the correct clocks, without artefacting or crashing.

If all seems fine, ignore it.

Also 280 = overclocked 7950, 280X = overclocked 7970

Hi,

I would recommend the following:

1. Follow the AMD guide to uninstall your drivers.
2. Once drivers are fully uninstalled and you've restarted your pc, please download the latest version of DDU.
3. Extract that in your downloads folder and run it. Allow it to set a system restore point and follow the prompts. Say yes and allow it to restart into safe mode.
4. Download and install the latest version of 14.12 Omega drivers from the AMD website.
5. Restart your pc to complete the install and then run 3dmark again.
 
i can confirm if you use AMD auto detect drivers for a 7950 guess what ?

it sees it as a AMD 280X and recommends 14.4 drivers :D

nothing wrong with that as 14.4 drivers are the best for them ;)
 
Thanks for the replies.

He says it's definitely a 280x he bought - so should be scoring the same as a 7970.

It's at PCI-E v3 in GPUZ, after running that test fuction. His motherboard (Asus Z97-A) is on the latest BIOS.

Will try all the rest of the suggestions tonight with him over teamviewer.
