There is a port of memtest86+ v4.2, but since the 5.01 claims July 2013 as its inception, I figured 4.20 would be even older, perhaps unable to work w/ this particular CPU. There is also something called 'memtester-4.3.0', would you happen to know anything about it ? The currently running memtest still shows its spinning state ASCII icon, & the time advances, but it the pass progress & test progress haven't changed in hours now .... -- William A.
