I'm working with an Asus ROG STRIX Z490-F GAMING motherboard and currently have two 8 GB sticks of G.Skill Ripjaws V DDR4-3600 CL16 memory. I've just added two more sticks of the same model for an upgrade, but now my PC won't post when all four are installed. The individual sticks work fine, as I've tested them in various combinations of two without any issues. I also cleared the CMOS and didn't find anything in the BIOS settings that needed adjusting. Can anyone suggest what else I might check?

Have you tried testing each of the four slots one by one? It could help rule out a faulty slot that might be preventing it from posting with all four sticks in place.

I haven't done that yet. The motherboard does recommend using specific slots for different amounts of RAM.
