I dug into my actual hardware using the tool 'inxi' (command inxi -m
-xxx) inxi is system information tool, you need proper memtest, not sysinfo,
that will not be limited by system. You want to use Memtest86+ [1]. It
requires usb stick where you put it, and boot a computer from it. synchronous
unbuffered (unregistered) UDIMMs, so I presume that means no error correction
capability. These has nothing to do with error correction. ECC has. [2][3]
