Enabling Multiple GPUs in BIOS: A Solution for Display Issues?

AI Thread Summary
To enable dual GPU functionality on a motherboard, it is recommended to access the BIOS settings and disable the PCIe slot for the second GPU initially. After installing the second GPU, reboot the system and re-enable the PCIe slot in BIOS. This process may help resolve issues where only one GPU is recognized. However, there are uncertainties regarding whether this solution will need to be repeated after each power cycle, and there is no guarantee that it will work as intended.

Hi PF!

I am trying to have 2 GPUs work on one MOBO, but currently the screen only works with one GPU installed (doesn't matter which). I contacted the MOBO manufacturer, and they said to go into BIOS and disable one of the PCIE slots pertaining to the second GPU. Then plug in the second GPU, reboot, go into BIOS and turn the PCIE slot on. Can anyone with experience confirm this (there was a slight communication barrier, so I want to ensure this is correct)?

Thanks so much

It seems reasonable. BIOS could have gotten off to a wrong start and this puts the machine back to a single GPU state and then later to a double GPU state.

Hopefully you won’t have to do this each time the machine is powered on or rebooted.

Of course, caveats galore here as it may not work anyway.

Alright, thanks. Just wanted to make sure! Oh gosh, why'd you even mention I might have to do this each time? LOL please no!
 
Well, the date has now passed, and Windows 10 is no longer supported. Hopefully, the readers of this forum have done one of the many ways this issue can be handled. If not, do a YouTube search and a smorgasbord of solutions will be returned. What I want to mention is that I chose to use a debloated Windows from a debloater. There are many available options, e.g., Chris Titus Utilities (I used a product called Velotic, which also features AI to prevent your computer from overheating etc...
