RE: [suse-amd64] Opteron Board preference ....
Yes, it's always important to check. Tyan's Tiger K8W Opteron boards,
MSI's 9130, etc. all limit memory slots to the first CPU. Most
workstation boards with AGP slots (like the HDAMB and the others just
listed) populate the RAM controllers of only one CPU. Tyan's Thunder
K8W and Arima's HDAMC are the notable exceptions.
But the Arima board has the longest track record of any fully populated
(with DIMM slots) board. At the time of Opteron's launch, when
Solectron refused to ship their AMD validated Opteron motherboards, the
Arima HDAMA was the only 8 DIMM board available, and it stayed that way
for a while. MSI shipped 4 and 6 DIMM boards at the time of the launch,
too. Tyan and Asus boards followed later. I'm certain that you are
well aware of all of this, but others might not be and it seemed like it
was worth noting that Arima's HDAMA fully supports all 4 memory
controllers and has the longest track record of any 8 DIMM Opteron
server board, with the possible exception of the AMD designed reference
boards used in Celestica systems (which are great boards, too, but can
only be bought inside a Celestica system).
Regards,
Dan
PS - Solectron's failure to ship was supposedly due to Intel influence,
but who really knows - all we know is that box makers didn't receive
their promised shipments, and I was told this by staff at several rather
stunned tier 2 box makers, all of which had orders to fill and were
scrambling to recover from Solectron's abrupt refusal to ship the AMD
validated Opteron boards they'd promised.

"Miller, Daniel J."
Support from the manufacturer for the Arima line of motherboards can be found here:
One word of caution with Arima: While their motherboards seem to be very stable (not much problems reported) some of them like the HDAMB are not true NUMA: they have the memory connected only to a single CPU. If you want a well scaling Opteron system I would avoid such designs. Other boards from Arima may be ok in this regard. This can be normally easily checked on board pictures - the traces from the DIMM slots to the CPUs are visible. They should lead to both CPU sockets. -Andi -- Check the List-Unsubscribe header to unsubscribe For additional commands, email: suse-amd64-help@suse.com
