Unfortunately that is true.  That is one of the reasons why I switched from my
previous Gigabyte AB350 board to the AX370-GAMING 5 after spending more on RAM
than CPU for this build.  The specs on the previous board were sufficiently
ambiguous that I though I could save $100 on a motherboard and still have
working ECC.

Unlike the earlier AM2->AM3+ Gigabyte boards that I have used that had all
sorts of BIOS knobs for ECC, the BIOS on this board has no mention of ECC at
all.  It just silently enables it if it sees ECC RAM.  I confirmed that by
booting Linux and with dmidecode.  Would be nice if the FreeBSD kernel
mentioned it ...

Unfortunately, Ryzen support wasn't added to memtest86 until today.  The
previous version just reported ECC unknown.
