Agreed...

I do have one in the new box, but for sys stuff only. Data goes on a
HD. 3Tb of SSD would be rather expensive. :-))

I'll check that...

I checked that out. There are 2 different versions, memtest86 and
memtest86+. memtest86 is newer [2016] than memtest86+ [2013]. I have
both bootable disks, and both crash almost immediately on the new box.
I can do a small bit of testing with memtest86, but none with
memtest86+. The memtest86+ site does not list CPU support for that
processor. May be a problem? The memtest86 site mentions UEFI boot
support. The new box does boot up UEFI - don't know how much that
influences what is happening.

And my now empty wallet, after the latest hardware buys. :-))

thanks for the info...
