I purchased two 1070 Ti GPUs and installed them on an Asus B450-F motherboard with an AMD Ryzen 5 2400G and Vega graphics. When I tried to install both GPUs, the system indicated they needed specific PCIe slots—PCIe 16x1 in the first slot and PCIe 16x3 in the third slot. Since my case has limited space and the third slot is occupied by the case itself, I’m unsure how to fit the second GPU without compromising the build. Is there a way to work around this CPU limitation so the second GPU appears properly? Please see the attached file for more details.

Certainly it doesn't function properly. PCIe16_2 is turned off when using APUs because they provide just 8 lanes for PCIe slots. PCIe16_3 succeeded since it connects directly to the chipset, and I won't assume you're attempting SLI.

Just for showing, if I get a Ryzen 5 3600, will it fit? Thanks!

3600 should function, just ensure the APU is updated in the BIOS first.

Thanks! I'm thinking about getting the 3600 with two GPUs—PCIe16_1 and PCIe16_2. Sounds good, ready to go!

Then it should function correctly.
