Hello guys I have the same issue as the guy in this thread

http://www.tomshardware.com/forum/353093-33-hd7950-help

But for me the bug is fixed with a computer restart what is the cause of this bug and how to fix it

My PC
Gigabyte P75
Intel core i5-3570K
sapphire HD 7950 OC --900 MHz
4 GB DDR3 ram
XFX Pro series 550 PSU

I managed to avert this issue by disable turning off the monitor option from (control panel > power options) as long as the windows does not turn off the monitor the card's PCI-E bandwidth is correct I hope this help anyone who have the same issue

Check in your BIOS if you can set your Primary display to PCI-E graphics or something to that extent.

Well, for one thing, you got a P75 motherboard where he has the Z77. That makes the situation entirely different. But problems such as those while similar in symptoms might still be very different in root cause. Just be happy that you got your problem fixed by a simple restart. Enjoy!

I checked the bios and the primary display is set to PCI-E graphics
My problem is that now I have to open the GPU-z each time I turn on my PC then restart if its x1 and thats annoying

I see. So there is still a problem...

What I suggest is that when you are at x1, try to play your games & take note of the performance (fps) and do the same when you are at x16. Just to know whether this glitch is causing you any performance hit or just a status error.

okay I will do that when the problem occur again

Have you tried updating the BIOS and/or the chipset driver for your motherboard?

My Bios and drivers are the latest

Games have lower FPS when this bug persists for example BF3 have around more than 55 fps ultra settings @1080p with this bug it have average less than 50

Your best solution is to talk to Gigabyte about the hardware bug.

I found that it only occur when the PC is left idle for along time

I think I found the cause of the problem
This issue occur when the monitor is turned off
all I did is to disable that option from control panel and now I don't have this issue any more

Hmmm.... just for curiosity check , I looked at my gpu setting ( GT9500 on a 2nd PC ) & gpu-z reports its at x4 and gpu is capable of x16. I usually hibernate this & also have the turn off monitor active. I do not notice any degradation because its a weak card anyway & not gaming here. But I have to check that for my 6950's on my gaming PC.
