System detects two GPUs in incorrect sequence
System detects two GPUs in incorrect sequence
i have two gpus installed, with the main one in the top slot and the secondary in a lower slot. however, the system assigns the top GPU as "gpu1" and the bottom one as "gpu0," which makes it favor the secondary over the primary. this causes the boot screen to appear only through the secondary during startup, just like with the bios. the main issue is that the secondary gpu is connected to a crt tv that can't show a clear image before windows loads. i can't access the bios without removing the secondary gpu, which isn't ideal. i've tried adjusting the gpus on the motherboard, but it doesn't seem to solve the problem. are there other options besides changing the gpus?
the top one is the 3060 ti and is identified as GPU1 by the system. and the bottom one is the AMD card and is being recognized as GPU0.
And the 3060 ti should be the primary GPU, right? If I understand correctly, then it should be GPU0. That means, if everything is correct, you'll need to change the GPUs on the motherboard. But there might be some mistakes in my thinking or in what I've read.
Still, it's not a bad idea to keep looking for other suggestions.
yes, the 3060 ti is intended as the main GPU. it's placed in the top slot, which makes sense for it also being GPU0.
why would a second GPU, added later and into a random slot, end up as GPU0 instead of the one in the top slot?
changing the positions isn't an option. this situation should be manageable through software adjustments.
Although it seems logical that the main slot should go to GPU0, this might not always be true based on how the boot sequence functions. Since the documentation is lacking or I'm too unmotivated to check, my guess is that the system first identifies all chipset-related devices because they could contain boot options, and then proceeds with the rest.
The secondary x16 PCIe slot is connected to the chipset, so anything linked to it will be found before the main x16 slot. In reality, graphics are just a convenience for users, so finding what's in the primary PCIe x16 slot later doesn't pose much of an issue.
