R9 290x low perfomance

Mingus81 · Nov 2, 2013

Hi all. I got a big problem

I just bought a R9 290x and i have very poor perfomance. My last card, AMD HD7850 perfomed the same as my new one. In Crysis 3 for an example. 20-30 fps on every setting and resolution with R9. I tried low res and low settings on everyting but with the same result. I have a i72600, 8 gigs of ram and a msi motherboard. Shouldent this be enough to perform better then 20-30 fps even on low settings? Hope someone could help me. And sorry about my bad english

What PSU are you using?
What Case are you using?
What are your temperatures in the case?
Did you make sure that you plugged in both PCI-e power connectors (I think one is 8 pin and the other is 6 pin)?

I use Corsair TX 850W PSU, mb MSI Z77A-GD55, case Fractal Design Define R3, Dont know about the temp. Yes i plugged both pins in

What resolution ?

lunyone · Nov 2, 2013

I'm assuming your running at the same resolution as before (1920x1080)??

If so I think you have something really going wrong with the GPU. I wouldn't suspect your PSU has an issue, although it wouldn't be the first time a quality PSU had an issue after a GPU upgrade.

I get the same result in 1080p as every other resolution. I dont win any fps even if i try it an 720p with everything on low

I bought the psu and installed it togehter with the new gpu so maybe its something wrong with the psu?

Do you have Vsync turned on by chance?

Mingus81 · Nov 2, 2013

Nope, no Vsync on

Is this problem with a complete clean install of the OS?

Mingus81 · Nov 2, 2013

I uninstalled the drivers and tried again with the same with no result. Then i installed the older drivers that came with the card and for som reason it works better with them. Now i have all maxed out settings in 1080p with a steady fps of about 40

Strange isnt it?

if you drop resolution and you dont gain fps, then its a cpu bottleneck. since ou have a good cpu, i would suggest that its overheating. Regards to the drivers, i would use driversweeper to remove all traces of drivers and registry entries, and try the latest whql driver.

I try and put another fan into my case tomorrow and do a driversweep. Ill let you know how its turns out. Thanks for all the help

I always use THIS video drive removal instructions. They seem to touch just about everywhere you need to remove it from on the system.

Hi again. Ive been of to work so i havent had the time to test things out but today when i got home i started out . I unpluged the psu and i saw that one of the pins didnt have contact. So i started over and connected every single component. I started the computer and voila. Perfect fps

BUT! Then i put on the cover to the case again and started the computer and i had the same problem. Very low fps. So i think maybe its to high temp in the case so I took the cover of again but with no result. Same low fps! Maybe the card is defect?

I'm betting that your connections to the GPU or wherever your cables run from the PSU to the GPU is your issue. I had a similar issue with a system that the owner of the system had run extender cables to the GPU and when I tried to close the case up the system would reboot. I found that the extender cable wasn't making a good contact with the PSU cable, so I pulled out the extender cable and the system no longer had any issues. So I would check all of you cables that are close to the case panel that you were putting on at the time of the problems.

Mingus81 · Nov 3, 2013

Ok

Thank you. Ill let you know how it turns out. New tries tomorrow.

Mingus81 · Nov 4, 2013

Ok, so now I have tried everything. Under the whole day everything went fine but as soon as i plugged my eathernet cable in and connected to the internet the same problem started all over again. So i plugged it out restarted the computer and good fps were back. I tried it many times with the same result. I dont get? How on earth could my network slow down my gpu?

lunyone · Nov 4, 2013

Sounds like a Mobo issue. I would contact your Mobo manufacturer and RMA it.

Mingus81 · Nov 6, 2013

I formated the computer and now everythings works just fine. Thanks for all your help
