ASUS R9 280X compatibility/ driver problem (AHCI)

[Ahmad Freeman]

Hello everyone, hope you are having a great day.

Just now I bought a used ASUS R9280X-DC2T-3GD5 & I've been spinning around for hours to get it running, it didnt output anything when it was on first PCIe slot, then I found http://www.tomshardware.com/answers/id-2121691/amd-drivers-amd-website-causing-windows-boot-failure.html ,so I decided to put the card in the second slot in my mobo (ASUS P8Z77-V PRO) & it worked!

Question is, how can I make the card run on the first PCIe slot?, and what does AHCI have to do with anything ?, & I cant disable ACHI because I have an SSD & my HDDs disappear when I do so. I reset CMOS, reinstalled drivers, couldn't fix it. Any Help is really appreciated .

Yes I'm using VGA with adapter, its connected to the graphics card indeed

Good, you wouldn't believe the amount of times I see "OMFG MY GPU ISNT WORKING WTF!!!!!!" and they've got their VGA cable plugged into their motherboard...

Just curious: Why VGA anyway?

Back to the main point, what are your GPU temps like? It almost sounds like either a power issue or that it's throttling due to high temps

My monitor is old with VGA only lol
As far as I can see, I'm getting 74 C on 100% GPU usage

See that shouldn't cause any issues :/

If you have a warranty on the 280x, I'd go ahead and RMA it. There seems to be some sort of underlying issue with it that we can't figure out

Where I live RMA is a headache & would take ages, plus I got it used so that'll cause more problems & more time, that's why I'm trying anything to fix it

Well I'm all out of ideas anyway. Just don't void your warranty trying to fix things

Seriously though, if there's even a question of "Will this void my warranty?" just leave it alone 😛

This is the Bus interface, 8x 2.0
Should effect the performance by any means?

[CGurrell]

I don't think so, not down to 5fps in BF3 anyway

 

[ingtar33]

his performance problems are likely due to the fact the 2nd pci-e slot on his motherboard is pci-e 2.0x4 which is VERY slow interface.

Im getting 30 fps @ 1080p Max settings on Hitman Absolution & Metro Last Light (Physx off). GPU temp hit 86C max & mobo hit 60C for the first time ever (maybe my room is too hot?) anyway, are those fps what im supposed to get? I expected a little more

Also, I found this http://www.eightforums.com/graphic-cards/4501-microsoft-basic-display-adapter.html , didnt work either

 

[Ahmad Freeman]

I always get x0 whether the 280x is connected or not http://s7.postimg.org/djdjra8t7/IMG_20140726_183111.jpg


Edit: refreshed my W8.1 just to make sure. Solved nothing.

Update: Its worse after refreshing, after windows 8.1 logo appears, the screen dims along with num lock, then nothing happens. After rebooting, Windows Repair launches. Installing drivers didnt go smoothly either. Note that windows works perfectly normal when 280x is unplugged.

Update 2: Now it only works when 560ti is plugged in first PCIe & 280x in the second one.

Update 3: A friend tried it on his PC, the 280x worked perfectly.

Final Update: Took them too long to diagnose & repair, it was a faulty motherboard, fortunately it was still under warranty, it was replaced with a new one.Thanks to everyone who helped me here.
