Upgrade AMD Bulldozer to Cezanne

I upgraded my desktop computer from AMD Bulldozer FX 8120 to AMD Cezanne 5700G. I also upgraded from a hard drive to M.2 SSD storage, upgraded from 16 GB DDR3 to 64 GB DDR4, upgraded from 21″ to 32″ 4K monitor. I bought the hardware from Mindfactory.

It was quite helpful that the RAM modules are illuminated. At first I was hesitant to press firmly the modules onto the motherboard. But using force when pressing was necessary.

Observed power consumption is now roughly 30 W when machine is mostly idle. The old Bulldozer machine did need at least 40-60 W when idle. See Plotting Power Consumption of my Desktop PC.

See also ASRock DeskMini A300M with AMD Ryzen 3400G. There I described the setup for the machine for the living room, which had separate requirements for power consumption and quieteness.
