Hi all,

In a previous thread, Paul advised me to look for the Tyan S5512GM2NR
motherboard for building an Intel ECC based system.
For the CPU, as Paul advised, I would take the relatively cheap Intel
Xeon E3-1275 Sandy Bridge.

Unfortunately, the Tyan S5512GM2NR is impossible to find in any shop
of the Internet's world.
I kept on searching and found the Asus P8B WS based on a 1155 socket
and an Intel C206 chipset which can also support the Xeon E3-1275.
It's also cheaper than the Tyan, has a sound interface and finally, it
is available in my street's computer shop ;-)

Here is the Asus P8B WS link:

http://www.asus.com/Motherboards/Int...specifications

I plan to install 3x4 GB of ECC DDR3-1333 RAM.

* What do you think of it ?

* Does someone here already use it and have an opinion ?

Thanks in advance for your reviews.

You start by checking the CPU Support list.

http://www.asus.com/Motherboards/Int...5/P8B_WS/#CPUS

"Intel Xeon E3-1275 (3.4G,1333,8MB,4C,D2) ALL 0401"

That means, as long as version 0401 or later of BIOS is installed
in the motherboard, it will be able to handle the E3-1275.

Eleven reviewers have written comments here (in the Feedback section).

http://www.newegg.com/Product/Produc...82E16813131725

"lemurcatta 7/10/2011 2:05:15 PM

ECC support not functional

...Now for some memory terminology. There is registered and non-registered
ECC memory. Registered (sometimes called buffered) is a totally separate
functionality from ECC memory correction. Bromolow chipset mobos will take
non-registered ECC memory. They will not work with registered ECC memory.

...

There is no evidence during post that non-registered ECC memory is detected.

If you need ECC functionality, get another Bromolow mobo. Try Tyan or
Supermicro mobos instead."

That's always a problem with motherboards, is verifying ECC actually works.
And that reviewer had a problem with the Asus board. Perhaps it could be
fixed via a BIOS update, but Asus updates the BIOS more frequently on
some of their boards, than on others, and a WS board may not receive
the same level of attention as some "overclocker" motherboard.

You can see more problems getting unbuffered ECC to work, here.

http://vip.asus.com/forum/view.aspx?...Language=en-us

You can check the download page, and see if a new BIOS is available.
If the BIOS has release notes, it may even indicate if changes
have been made in the ECC area.

http://support.asus.com/Download.asp...%20WS&p=1&s=39

You can also get the manual, while you're there, and see how
poorly the section on installing memory is worded.

http://dlcdnet.asus.com/pub/ASUS/mb/...384_P8B_WS.pdf

The processor datasheet is here. Normally, I wouldn't bother, but I had
trouble getting this from their site. This will save you a couple minutes.

http://www.intel.com//content/dam/do...-datasheet.pdf
http://www.intel.com//content/dam/do...-datasheet.pdf

I found this description a bit corny, seeing as the memory interface is
on the processor itself. This is a tradition with Intel datasheets,
making statements like this without giving background info, as to why
such a situation might exist.

"The type of memory supported by the processor is dependent on the PCH SKU
in the target platform

— Advanced Server/Workstation PCH platforms support
ECC and non-ECC unbuffered DIMMs

— Essential and Standard Server PCH platforms support
ECC un-buffered DIMMs"

In any case, it uses unbuffered memory (not registered). It would be
a DIMM, with nine memory chips per side (usually) and no register
chips or clock buffer PLL. There is no point in using buffered
memory, since there are only four DIMM slots.

OK, thanks for this precision.

After reading the mobo reviews, I even found people who did not manage
to get some ECC RAM working with this mobo.

You definitely convinced me not to buy it.

I am living in France and want to get support for this quite expensive
product.
Newegg is too far away for me : it would have to pay excessive
postage, tax and of course pay postage again if I need to return it
back in case of hardware failure.
The only serious French site which sells Tyan or Supermicro or more
generally Intel C200 chipset serie-based mobo is LDLC.com:

Here is a search for the C204 chipset:

http://www.ldlc.com/navigation/cat.h...tre_150_3_val=

All Tyan and Supermicro mobos are unavailable.
It seems that I could get the ASUS P8B-E/4L with a 10 days delay.
Here is the Newegg link:

http://www.newegg.com/Product/Produc...S%20P8B-E%2f4L

I did find any feedback yet about the ECC support.
I you know other brand or chipset which is know as well handling ECC
memory, you are welcome.
I would not like to spend more than $300 for the mobo.

Noticed you nixed newegg in your next comment... Oh well

For an opinion, I would pass on the Sandy Bridge now, and wait for the next
batch at the end of the year or beginning of the next.

Paul gave me that same advice. But #1 I couldn't wait, and #2 I don't care
for the Sandy Bridge.

If a person was to contact Tyan (Mitac) directly, they might be
given the names of some retailers. The Tyan people probably
know their distribution system the best.

If that didn't work, a search of the forums of 2cpu.com would
probably dig up some Tyan info. You could always ask here for
some sales leads. There are lots of discussions about server
boards here.

First of all, I will not buy any of the ASUS P8B-serie (Bromolow
mobos) motherboards.
I read all the ASUS manuals and none of their BIOS have an ECC section
so there is no proof ECC really works for this boards (like you said).
So, Paul, you are right, Tyan seems to be the (only) brand which
handles ECC RAM correctly.

As far as I am concerned, I want a Xeon E3-1275 CPU (other ones are
too expensive for me) and want ECC memory so I think I have a very
little mobos' choice (C20X / Bromolow).

* So what do you mean by "I would pass on the Sandy Bridge now" and
"wait for the next batch at the end of the year" ?

* Do you have an information about the next release of motherboards ?

Actutally, I can not wait because I need a new computer for my work
(my current mobo has a faulty component).

I went on the Tyan "Where to buy" page then list of the resellers:

http://www.tyan.com/wtb_europe.aspx

Unfortunately, most of them only build servers for big companies using
Tyan motherboards.
I found a German web site (http://www.alternate.de) selling my Tyan's
mobos but they are unavailable at the moment.

Yes, I will do this.

Thanks you both.

I didn't write this. And getting the E3-1275 right now is just fine
as far as I'm concerned.

If you ask on the 2cpu.com forums, they may be able to tell you of
other sources of the Tyan motherboards.

HTH,
Paul

I am sorry, I replied/asked to you instead of Pennywise.

I am going to do it.
Thanks for your advice.

I posted my request but it seems that nobody could help me on the 2cpu
forums.
Anyway, I succeeded in contacting the French company LDLC.
Here is the product's reference:

http://www.ldlc.com/fiche/PB00115676.html

In facts, they never store this motherboard because the demand is very
low. They just order when you order and you have to wait for a minimum
of 2 weeks before can get it.
The European demand seems to be very low for that kind of product. The
hotliner told me that they only had one ordered in 6 months.

Moreover, he explains me that it is difficult for them to order Tyan
products (I suppose this is because of the low demand again !).
