We also have these boards, I've found them unusable under
FreeBSD/5.3-STABLE with 8GB of RAM--other qualities appear to work okay.
But I even saw some infrequent problems with 6GB.
FreeBSD/amd64 is not in my opinion not actually a stable tier 1 quality
release under these configurations, too many problems remain--especially
in regards to ia32 emulation.
Exigencies of the moment forced us to forgo further debugging and adopt
linux/amd64. (Sadly, some people actually have to get work done on their
To anyone who wants to peg these problems on hardware, running linux these
machines have operated without fault while under a mix of high
computational and i/o load. moreover, the machines were tested
extensively using memtest+ in a controlled ambient temperature range from
60F to 80F.
This is a really lamentable situation. We've been a primarily FreeBSD
shop for 10 years now and for the past 4 years or so a pure FreeBSD shop.
Switching to linux on just these machines has been quite the headache but
I'm holding on to the hope that FreeBSD/amd64 will shape up.
FYI, most of the positive reports I've seen regarding FreeBSD and this
motherboard are 2GB setups. In my own testing that arrangement worked
Addendum: The RAM timing is a bit marginal on the second processor. i.e.,
RAM that runs fine under extensive memtest+ ing has trouble
doing 400MHz DDR on the Second Processor. We ended up running
it at 333MHz DDR
