Pciex bug on Asus Strix B360-F

[jm_bmw]

What is happening is that it randomly boots in either 3.0 or 1.1 pciex mode, and I did run the test, it doesn't change.

Get a new motherboard the gpu cannot be blamed for it transitioning into 1.1 instead of 3.0.

 

Maybe test another Graphics card that is also PCIe 3.0 to make sure it’s the Motherboard.

 

Hope that helps

Thank you, I am also 99% sure its the motherboard as the gpu always worked @3.0 on my previous board.

 

Unfortunately I do not have another vga to test right now.

Update the Motherboard BIOS to the latest version and Update the Firmware aswell to check if that changed anything.

Press the "?" button next to the "PCIe x160 3.0 @ ____" .

A pop-up menu should come up; press the "Start Render Test" button.

While that is running, does it still say "@ x16 1.1", or "@ x16 3.0" ??

 

*Some* motherboards, from what I know, will drop the bus down to 1.1 during idle / low usage.

Again, as quote from GPU-Z

Power saving features may affect the results displayed.

 

I don't recall it is something on the motherboard that you can enabled/disable.

 

EDIT:

Oh! I recall in Windows, in Control Panel >> Power Options, there are setting or two about "PCI Express" and "Processor Power Management."

I typically run my systems on 'High Performance' mode, rather than 'Balanced' so...GPU-Z seems to constantly show "@ x16 3.0" for me.

 

Ah yes, if on 'High Performance' mode, "PCI Express Link State Power Management" setting is on [Off]

When on 'Balanced' mode, "PCI Express Link State Power Management" setting is set to [Moderate Power Savings]

They are both updated to the latest version

Yes I did all that and even running render in the ? mark doesn't change.

 

It is like a bug, if I get lucky it boots on 3.0 mode. If it boots on 1.1 nothing will change it, doesn't matter running render/games etc.
