Hey all

I'm running a sapphire 7950 OC edition and noticed something odd with the latest version of GPU-Z

Under bus interface it shows PCI-E 3.0 x16 @ x1 2.0

Shouldn't it be @x16 2.0? I've double checked to make sure I have my card in the right slot on my sabertooth 990fx for a single card setup. Have also pulled the card out then placed it back in to make sure it sits right, nice and snug, firmly in place.

Try putting a load on the GPU and see what it does.

Okay, yeah, that's likely not a false reading then.:| It should be x16 2.0 when under load.

Unfortunately not really. I haven't used an AMD platform in a long time.:(

Im starting to think it's a bug, looks like after I reboot GPUz and CPUID both read that Im running @16x 1.1 (or 2.0 at load) ..
Then this morning after about 7 or 8 hours of idle time, its back to showing my card is at 1x 1.1/2.0
I don't have pci express power saving feature turned on in windows and my computer doesn't sleep/hibernate, it only turns off my monitor after an hour.

So I ran 3dmark and I get the same score as when it showed 16x 0.o

Maybe 12.2 driver funk? Someone suggested to me I try 12.3 or even 12.4 beta driver.
