wtp2019 went down on 09-13 and showed "Uncorrectable Memory Error " at bootup.
after powercycling it came back like normal
then it ran ok for a couple days and went down again 09-18/19, this time not showing an error, just being down.
again it came back after a powercycle and didn't show the error, but since it happened more than once now,
let's check the RAM / board.
