But, nothing worked. I tried all three CPUs in this B350 motherboard and then I realized that the motherboard wasn't going to recognize these CPUs until it had a BIOS update (the Gigabyte website said these CPUs would work). But alas, I could not do a BIOS update on this motherboard without a working CPU to start with. I wasn't going to tear one of my old machines apart to get to an earlier Ryzen CPU, so instead I ordered a new Asus X570+ motherboard from Amazon (It arrived the same day!). I tried the AMD 3950X CPU in the new Asus motherboard and no joy. Apparently this CPU is dead. So, I put in the AMD 3600X CPU and it finally booted into the BIOS. Soon I had Windows 11 installed (remember to enable firmware ftm in the BIOS for Windows 11) and now I can proceed with the build into the case.
So now you see the importance of building up the system outside of the case. I would have been pretty upset pulling the motherboard out of the case multiple times as I swapped the CPU. This next week I will get the components into the old Thermaltake Level-10 GT case (which I will now call 'Level-Up' as a new gaming machine on my LAN).
This case has 5.25 inch bays, so I can use some older Cooler Master parts and optical drives.The original components (new monitor not shown here).Cooler Master Hyper 212 RGB was mounted and removed multiple times!Initial build up.No joy here. I just got the 'CPU' error LED on the motherboard.Trying the AMD Ryzen 3600X CPU, this time with a new motherboard.Looking good! The LED error lights sequenced through their checks to a green LED.And we are into the BIOS of the new Asus X570+ motherboard.
