PCIe 2.1 x16 @x2

[MrJets]

My video card is a PCI Express 2.1 x16, but it's running as PCI Express 2.0 x2. My motherboard says it supports PCIe 2.0(but doesn't specifically say 2.1) x16, but I find it hard to believe that would be the reason it's running @x2 and I can't get it to x16. I hope someone can help me.

Here's a screenshot of GPUz, if it helps.

Have you ever ever ever download the chipset driver where the igp gets installed with it.

No cause I haven't ever own a mobo with an igp. But on the 790GX chipset the igp is integrated into the 790GX northbridge so I thought it would be included in the drivers bundle with all the other crap.
thats why I said 'I think'

Alright, well I have installed the Chipset software provided from ASUS and it brings up ATI Install Manager. That was why I said what I did about it installing the onboard gfx. Anyways, since running that, there's been no change and at the end of the setup it tells me that warnings had occurred. So I view the log and see no warnings or errors, very strange.

Are there any other chipset drivers options for me?

This is what's bothering me. Sorry for coming back now I see you were assisted nicely. But ko888 can check as well look at what aida showed
GPU Clock 157 MHz<--------- that's a bit low ain't it? Power supply maybe?
Op your gpu-z screenshot show 5800 series yet your gpu is the 5770. I suggest you do a clean sweep of the drivers by using a driver sweeper.

complete garbage comment.This comment shows you have zero idea about gpu.

That gpu is a pci-e 2.0 card. Altough the mobo is a 2.1 slot that @ 2 means actually 2.1. the slot is backward compatible so are the devices. All that show is that you 2.0 card is running at x16 but 2.0 revision. which means not less bandwith just older transmitting features its doing. nothing to worry about. Gpu-z just displayed it strange

Another garbage comment by daddigle.That gpu is pci express 2.1 card.But all mobo present in the current market has pci express 2.0 slot.

@OP since you have tried almost every thing.Plz do this following set win7 power profile to high performance.Then downgrade the bios to previous version.Sometimes bug in the new bios can cause it.

So no one ever really commented on what I said earlier, when I said:

So I downloaded 3DMark Vantage and I'm comparing things to this http://www.tomshardware.com/reviews/radeon-hd-5770,2446-5.html

GPU Test Results:
Performance - 9033
High - 6261

Those scores are actually a bit higher than what is in the graphs, does this mean that it's running at x16 but software is seeing it as x2?

Were you using the same AMD Catalyst 9.9 driver that the Tom's Hardware review used?

You would expect later driver versions to improve the performance.

At x2 I would thinks you you see a less than 10% drop in performance than if you were running at x16.

I downgraded my BIOS as far as I could. None of the different versions I tried had any affect.

So I emailed BIOSTAR, telling them about my issue. I just got a response from them:

This video card maximum bandwidth is PCI-E 2.0 16x. Please contact the motherboard manufacturer for help with this case.

I get the feeling that if I contact ASUS about this issue, they'll tell me to contact BIOSTAR. I really want my card to perform as advertised so I'll email ASUS next and see what they tell me.

It wouldn't be the graphics card that limits the PCIe lanes because it has no idea what you have plugged into the other PCIe slots.

It's the motherboard that decides the PCIe lane availability and usage.
