I'm looking to build a high end server / workstation and am
considering the Tyan K8QW board.

Does anyone have this board running with all 4 CPU's installed? And /
or all 16 DIMM banks populated? If so, what is your experience?

I can't find anyone so far elsewhere on the net who has this board
running with all CPU and DIMM slots populated.

I'm also wondering if it supports SLI. I can't find anything on
tyan.com to indicate that it does, as one of the PCI-e slots appears
to be 4x while the other is 16x.

The other thing that worries me about this board is that it wants
PC3200 registered DDR400 DIMMs, and these are VERY hard to find
available for sale. The average price for a 2 gig DIMM of this type is
around $300 - $400, but I spent about an hour so far on various search
sites and every vendor I find shows "Out of stock" ... and 4 gig DIMMs
of this type are even more rare, with the price increasing per DIMM by
around 6 times... average price for a 4 gig PC3200 DDR400 registered
DIMM is $2,000. (You would have to use 4 gig DIMMs if you wanted to
achieve the board's advertised 64 gig capability.)

There is at least one pre-sales telephone number on this page.

http://www.tyan.com/archive/html/contact.html

Have you looked at the brochure ? It almost suggests the best
way to do it, is 32 sticks of 2GB each. And the expansion
motherboard. And the two riser PCBs, that connect the two motherboards
together. Plus the eight processors. Maybe a 1KW power supply.
A nice cheap project.

ftp://ftp.tyan.com/datasheets/d_s4881_104.pdf

Limit 10 per customer. $270 a piece. 32 would be $8640.

Talk to the people on this forum. Even if their personal machines
don't have 64GB, they may have built them at work. You have to
register, to use their forum search engine.

You could try pricewatch.com, to find some suppliers. This
is the results of a search for the 2GB registered PC3200 sticks.

http://castle.pricewatch.com/s/search.asp?s=KVR400D4R3A%2F2G

You can check retailers here, by entering the name of the
company where it says "Enter store name".

Maybe Tyan Pre-Sales can suggest someone to build it
for you.

Have fun,

Dear Nag,

that is indeed very high end. An equivalent Dell server runs about $20,000.

That is such high end gear that most likely it's in a production
environment--pretty rich for a workstation.

It looks like it does support SLI:

Here is the manual:

http://www.tyan.com/support_download_manuals.aspx?model=S.S4881

Search of manual for SLI: not found.

Tyan website does *not* list this model as supporting SLI:

Here is a 4 Opteron core Sun Machine:

About the same $20K price range out the door....if you have the need for
that much computing power and the budget for it, may I suggest that you
shouldn't be Googling for the memory....there is a salesperson out there
who would love to help, either a Sun reseller or sun.com...or dell.com,
hp.com: that way you get some support, and a warranty....if such an
expensive machine is justifiable, downtime can get expensive fast.

Whomever makes the software you run that needs all that horsepower can
most likely recommend a good reseller/dealer/manufacturer to provide you
with a reliable integrated system.

HTH,

BC
