Question My gpu is running at pcie gen 3, why???

[Vetrix1996]

Do i update the bios? I have a 4090 with ASUS TUF Z590 and a 11900k CPU. It should all be gen 4 but its running at gen 3. I went into the bios and it also only goes up to gen 3 there too.

Which BIOS version are you currently on for your motherboard?

Then you have BIOS versions pending update, note the MEI drivers as well, and do them in tandem with your BIOS updates, taking note of the dates for each.

Did you clear the CMOS after making sure your BIOS update was successful?

You mean reset everything to default?

Advanced -> System Agent (SA) Configuration -> PCI Express Configuration
Advanced -> PCH Configuration -> PCI Express Configuration.

Advanced -> PCH Configuration -> PCI Express Configuration.

oh yeah i tried that earlier, it only goes up to gen 3. Worked fine on my 3090. This 4090 is brand new, i got it days ago

Using a pcie riser cable?

no, default nvidia cables

Advanced -> System Agent (SA) Configuration -> PCI Express Configuration
Advanced -> PCH Configuration -> PCI Express Configuration.

The setting above it, something called pcie 16_1 allows me to go into gen 4 but not the Express Configuration, it maxes out at gen 3

Maybe the pcie slot is broken? But i assume that if it was broken then it would not work at all

You should have the option to change it to 4.0

If your gaming and not just running benchmarks this says no biggie.

Has to be a bug, it only goes up to Gen 3. pcie 16_1 allows me to go into gen 4 but the Express Configuration is stuck at gen 3.

der8auer has a similar problem, he is stuck at 8x pcie but at gen 4. I am stuck in gen 3 but at x16

PCIE riser cable is this thing - for installing graphics card vertically.
