Sometimes my computer recognizes my R9 280 as a HD7900

Hi guys!

 

I just built my first rig, and installed a Gigabyte Radeon R9 280 on a Gigabyte Z97 MX-Gaming 5 motherboard. Running Windows 8.1, on a slightly overclocked Pentium G3258 (4.0ghz) and an overkill power supply. Intel SSD HD.

 

Sometimes when my computer starts up, it will not recognize my R9 280, and instead calls it a HD7900. Other times, it will recognize it just fine. Anyone have any idea what might be causing this problem? All drivers are up to date, and i just upgraded my motherboard BIOS. There are never ANY heat problems!

 

Also, I am having slight issues steadily overclocking my processor. RIght now it never peaks 65C, but Windows will still not always boot correctly. It is a paid for and registered Windows 8.1 Professional, but I had to download the .ISO-file from piratebay, as I only own a mac and had to create a bootable USB-drive to install it. I don`t know if this is relevant, but i`ll just throw it out there.

 

Thanks guys!

 

Edit: It shows the wrong graphics card in both HWmonitor AND GPU-Z.

Edit 2: Added a screenshot. It is weird, as it shows all the specs right, it just gets the model (and the number of fans) wrong.

Sounds like a driver issue

I don't see how this is a problem, as long as the card runs. As to the stability issue, does it happen when you run your CPU at stock clock?

It shows up as HD 7900 because it used the same ship as the HD 7950.

This happens to me too, but I have a  7950 and it shows up as a R9 280.

 

 

The problems you are having with windows are probably because of the way you got it.

I guess it is not a problem apart from the fact that I do not get accurate readings of all the fans for instance, and all games automatically sets the settings to low quality.

 

Yes, it still happens when I run it at stock clock, though not as frequently. It wont even boot into bios sometimes, just gives me a black stare.

And it is not a problem except for the displayment of wrong information?

They are essentially the same card.

In fact, you can crossfire them.

The only difference is the name and the clock speed and bios and stuff like that.

Nope. 280 and 7950 are the same card, so actually, it's correct information.

AMD use the same GPU chip like HD 7950 for R9 280 and HD  7970 for R9 280X. They just rebrand the cards and cut prices, nothing more. Is no problem, the driver miss judge the real chip factor name :)

CPU : Intel i7 2600K OC@ 4.5 GHz ;

MOB : ASUS P8Z68-V/GEN3 ;

RAM : Corsair 8 GB DDR3 1866 MHz ;

GPU : EVGA GTX 680 2Gb (GTX 770 Bios modded and instaled with voltage and fan speed unlock) OC@ 1228 MHz on GPU and 7012 MHz on Memory ;

Check if theres a BIOS update available for your GPU

Oh, okay!

Yeah I did, there isnt, but it seems to just be a problem with the system reading the chip wrong.
