I have a second GPU assigned for rendering tasks and it’s linked to this card. But it doesn’t transmit data to the display unless I reboot the system. On startup, the first PCIe port is always chosen. I want the OS to favor the second port where the less powerful GPU resides. After reinserting the card, I checked the BIOS for any options to prioritize the second GPU, but nothing changed. I modified a setting to give preference to PCIe over integrated graphics. I considered swapping the weaker GPU into the first slot and the stronger one into the second, but that’s not the best setup. I also observed that a restart is usually required after more than 12 hours of use. Perhaps there’s a hardware problem? I’ve also tried sleeping the PC for 24 hours and then waking it, but it still favors the primary GPU. Specs: Windows 11, ASUS Z270-A, Intel 7700K, 32GB RAM, main GPU 1070Ti, secondary GPU 1650S, 650W PSU.

I noticed this earlier but chose to pause it due to its complexity. I thought another person might understand the situation. With no replies yet, I’m wondering if you’re working on something and if a 1650S could assist with frame generation. Are you using any specific resources or tools?

I'm working with a tool named Lossless Scaling that lets me use a second GPU only for creating frames. Usually, when generating extra frames on the main card, resources must be assigned to produce those frames. But using a second GPU for frame generation frees up those resources on the main card. The best setup is placing the main GPU in PCIe slot 1 and the weaker GPU in slot 2, with the display linked to the weaker one. The weaker card must send the signal to the monitor; otherwise, there would be extra processing between the two cards. I've tried connecting the display to the main GPU while running frame generation on the weaker GPU, but my FPS dropped significantly. My problem is that the second GPU doesn't show anything on the screen at first startup—it needs a restart before it appears.
