Ryzen 3600 won't boot on B450 with BIOS update

I have a new Ryzen 3600 and B450 motherboard, which when I received them would not POST and produced a steady VRAM light. I confirmed with AMD support that this was due to a BIOS update needed by the B450 to support the 3600, so I got an Athlon boot kit via AMD. The Athlon processor POST succeeded and I updated my BIOS to F40, which is the manufacturer-recommended version to run a Ryzen 3600. But when I put the 3600 back in the socket, I still get a steady VRAM light and no POST. I have tried moving the RAM to each socket and running without RAM, but the result is the same (and I doubt that's the problem since the Athlon works fine). Any help would be appreciated.
