Help with graphic card issue please.

[Consfearacy]

I have just completed a clean OS install to get my rig ready for a LAN comming up at the weekend and when I was looking at GPU-Z I noticed the strangest thing. My graphics card was only running at x8 on a x16 slot.



After the install I updated my Bios and all other relevant drivers and this is still an issue that is confusing me like crazy.


I have look up and tried a multitude of fixes and multiple re-installs of drivers/Bios still running at x8.

Can anyone shed a little light on this issue please as I am now starting to panic a little it being so close to LAN.

Thank you in advance to anyone who can contribute any constructive help.

FWIW it will only equate to at most 1-3% performance drop, if that. Not sure how to fix it though, GPU-z has been wrong before mind you.

Some power features can cause erronous reports like that - if you hover your mouse over the box next to bus interface in GPU-Z itself it states this in the tooltip window.

Maybe this could be the cause?

Not wanting to sound like I'm teaching grandmother to suck eggs, but:

a) I assume you don't have anything plugged into the other x16 slot?
b) have you tried the card in both x16 slots?

Otherwise it could just be a registering incorrectly in GPU-Z: not sure how else you could do check this though...

My HD5850 1GB runs fine in a first generation PCI-E 1.0 8X slot. With an HD5770 1GB you will not see a noticeable drop in performance in most games IMHO even if the slot is running at PCI-E 2.0 8X.

This article does not use the latest games but is worth having a look at though:

Sounds like you got it sorted, but for future reference, it's no reason to panic: http://www.tomshardware.com/reviews/...8-x4,2696.html

Edit: Beaten to it. More reassurance though.
