How to fix version of PCIe 16x slot?

[EarthDog]

I would try reseating the card as well (power off the system of course). That said, the performance loss is negligible with 8x to 16x so I wouldnt worry too much.

Haha, this isn't my first build

Cheers for the advise guys, I'll get back to you once I quit playing ArmA2 for 5 minutes and get a go at reseating this card and blowing out the ports etc.

Hi

Regarding my little issue, I tried underclocking my CPU and lowering the voltage to give it max stability and ran that test on GPU-Z. I ran it for 15 minutes in both full-screen and in the windowed mode and nothing changed. Any ideas?

You have checked the PCI Subsystem Settings in bios
Press <Enter> to enter the sub-menu.
PCIE GEN3 allows PCIe 3.0 slots support expansion cards with PCIe generation 3.0 link speed.
Set to [Enabled]

Test system with another spare vga card and or borrow one from a friend
Test vga card in another PCIe slot
Remove vga card; check PCIe slot and clean with can of air duster, clean blades of the vga card; use a coffee filter and isopropyl alcohol & reseat card

dose it do this with windows 7 loaded; if have a spare drive may be worth checking

*if above fails as a last resort - reseat CPU & check with minimal hardware; PSU, CPU & Heatsink, one stick of RAM and ssd/hdd

Hey Law,

I gave that a try this morning whilst I was off work. Still no joy with it.

I cranked up the clocks and ran a burn-in test while I monitored the temps and didn't see anything out of the ordinary. Perhaps you do?

Thanks.

Possibilities
Set default bios settings before testing
Link speed of the PCIe bus is being read incorrectly by third party softwares [*however improbable]
Link speed bug in bios [may require bios update]
Hardware issue with PCIe x16 slot on motherboard [test with another vga card]
Edit: Igp has stolen bandwidth from the PCIe lane; double check this is disabled

Try setting the PCIe 3.0 x16 to backwards compatibility to 2.0~1.0 by disabling the following setting in system bios:

PCIE GEN3 allows PCIe 3.0 slots support expansion cards with PCIe generation 3.0 link speed.
Set to [Enabled] (change this to disabled) save and exit bios
run same test and monitor with GPU-Z as in this post #10

Note: when testing a system run no overclocks
