X670 Extreme - PCI-E 4 does not wake up after sleep

[xbohdpukc]

Basically subj. I have a CamLink Pro installed in the PCI 3 slot, which is PCI 4.0 x8.

After computer goes to sleep or hibernate and comes back CamLink is nowhere to be found in the Device Manager. It takes a full reboot to get it back. I saw similar problems posted by people with other mfgs' x670, so not sure if that's the chipset, platform, or CamLink problem. Anyone has a similar experience, or even better, know of a fix?

Hi in windows go to power options, click on your schematic and change the advanced power options. In the PCI Express tab, turn off power saving!

Just for the record, the same thing happens with USB. For example, when I plug in my iPhone, and the save is turned on in the USB settings, it disconnects after a while. So you need to disable USB sleep in the settings I wrote above as well.

Appreciate the thought - that is already off.

Are the 4 stick sets like this (CORSAIR Vengeance RGB 192GB (4 x 48GB) 288-Pin PC RAM DDR5 5200 (PC5 41600) Desktop Memory Model CMK...) supposed to be working at the declared speed? Otherwise it's just nothing but false advertizing?

If the above suggestion didn't work, this may be an issue with incompatibility with PCIE Gen 4. You could try to go into your mobo's bios and then force GEN 3 for the applicable PCIE port, and see if that solves the issue.

I remember when PCIE Gen 4 first came out, my Creative Labs sound card would randomly swab left audio channel with right during gaming session or reboots.
