Unexpected benefit with Ryzen – reducing power for home server

I received an unexpected benefit today when I checked for BIOS updates and
found that my ASRock AB350M Pro4 Ryzen motherboard now supports ECC. I
decided that it is finally time to upgrade my home server from the
venerable E3-1270 (Xeon, 3.4GHz, 4-core/8-thread) to the 2700X (Ryzen,
~4.1GHz, 8-core/16-thread).

In doing so, I am using ECC memory and the only EUDIMMs I have are 2133.
At those memory frequencies, overclocking the cpu itself doesn’t really add
much benefit so I decided to test just how LOW a power envelope I could set
and still retain full multi-threaded performance for compile jobs. That
is, the system is limited by relatively low memory bandwidth so there’s no
need to overclock the cpu itself. It turns out… really low! Ryzen CPUs
are very sensitive to memory bandwidth.

To make these changes I tell the BIOS to use the AMD CBS settings (usually

With that in mind, today we are removing all versions of the app from sale. We’ll continue to run the sync service for another 60 days, then take it offline at the end of October. Brent Simmons, who founded the app, shared what he plans to do with the brand name: […] I want to thank them [Black Pixel] for a second thing: their incredible generosity in bringing it
