I've been using my system with a 13700k CPU and a Gigabyte Z790 motherboard for three years without any issues, running four sticks of 16GB DDR5-6000 RAM. About a week ago, I updated the BIOS, and now my PC won't post when all four RAM sticks are installed—the DRAM light is on. However, when I try booting with just one kit of RAM, it starts up fine every time. I've tested both RAM kits in every slot, and they work individually but fail to boot when all four are in. I've rolled back the BIOS and reset the CMOS, but nothing has changed. Any advice on what might be causing this or what I should try next?

You might want to check your XMP settings in the BIOS. Sometimes, resetting or tweaking those can resolve compatibility issues after a BIOS update.

Yeah, but it seems like it won't even post with four sticks in, right?
