Since yesterday I've been having an issue where when I boot up my computer from a powered off state, it will not always recognize that I have a 2nd GPU and monitor installed. When it boots only my main monitor will display and the device manager will only show one of my 2 GPUs . Also the nVidia control panel will be missing from the right click options on the display and geForce Experience will not be shown down in the taskbar. I'm honestly not sure if this is a software or hardware problem, or a BIOS issue.
The most recent change I made to my computer was I switched from running a single Asus PG348Q 34" ultrawide to now running a 27" Asus PG27UQ along side a Dell P2314H in a dual monitor configuration. I made the change on Monday and didn't have any issues until Wednesday and turned off the PC several times after changing the setup.
Yesterday when I woke up and powered on my computer I noticed the issue for the first time. I played with it for a bit and tried a few trouble shooting steps and eventually got both GPUs to display, but after powering off and on again the issue reappeared. I've seen the issue resolve itself both when I'm in Windows or when I'm in the BIOS. What I mean by this is I notice the lights on the NVLink SLI bridge will all of a sudden turn on, so its like its just all of a sudden has power or something.
Things I've tried so far:
1.) Clean uninstall of GPU drivers using DDU in safemode and then reinstalling the latest drivers with and without geforce.
2.) Updated Primary Display in BIOS to be PCIE as well as updating link speed to be GEN3
3.) purchased and installed a new NvLink bridge.
4.) wiggled parts, ensured both GPUs were seated well.
My computer specs are as follows:
i9-9900K overclocked to 5GHz
32GB G.Skill trident DDR4 RAM
2 x 2080ti nVidia reference cards
Asus Maximus XI Formula Mobo
Asus Thor 1200W psu
My computer also has a custom hard line water cooling loop I did, so simply moving a GPU to the other slot and trying that is a huge hassle involving draining the loop, cutting new tubes to fit, refilling the loop, then testing.
