PCI-E 2.0 x8 at 5 GT/S for a few seconds?

[beclauss]

Okay, I'm well aware PCI-E 2.0 x8 and x16 are almost NELGIGIBLE, but I'm also aware PCI-E 2.0 x8= 2.5 GT/S, but when I clicked on my board explorer, it would still appear as x8, but at 5 GT/S for a FEW brief seconds. Any help here? Specs:

Intel Core i5-4570
8 GB RAM
GTX 760
600W PSU
MSI H81M-E33
2 TB Seagate Barracuda

It'll SAY 5 GT/S but after a few seconds, it'll go down to 2.5 GT/S and stay there. Any help would be greatly appreciated.

EDIT: I post this particularly because PCI-E 2.0 x16= 5 GT/S and this makes me think I'm actually RUNNING at that speed for a few seconds until it goes back to x8.

PCIe 2.0 is 5 GT/s regardless of the number of lanes. If you think of it as a highway, 5 GT/s is the speed limit while the lanes are like the lanes.

It can downclock when there's low load though, to save power. Try running a stress test and monitoring it. Should stay pegged at 5 GT/s then.

Tried stress-testing it, still runs at x8.

Yeah I stress tested it using GPU-Z, still runs at x8. Any other suggestions on whats going on?

Maybe it's set to x8 in BIOS.

GPU-Z will read 1.1 to 3.0 for modern GPUs that can use any adaptive power settings and boost technology.

graphics cards are not going saturate the full bandwidth of PCI express at this time.

is that sort of what ur asking?

What I'm asking is, why does my PCI-E slot tell me it runs at 5 GT/S (which is what x16 is) for the first few seconds when I restart my computer? I've always thought this slot is damaged to the point where it CAN'T run@ x16, but it looks like I'm wrong. So right now, I'm digging on how I can possibly fix this.
