Dual socket 939 boards available?

Lurking for a while and thought I'd ask the question now that the 939 FX's
are out. Does anyone know if a manufacturer has released or plans to
release a dual socket board for those CPU's?

No. They aren't dual cpu's. If you want dual, you'll have to use the
Opteron series 2xx.

That seems kind of silly. The 939 is supposed to phase out the 940, which
is dual, but the 939 isn't?

According to Anandtech AMD are going to make dual cpu's on a single die
sometime next year.. But of course they will require yet another type of
skt:-(

On dual systems stability is more important than the last bit of
performance

The 939 isn't slated to phase out the 940. It was intended to phase out
socket 754.

Before 939, you had to use a 940 for dual channel memory, and the memory
had to be registered. 939, is just an addition to the line using dual
channel unregistered memory This brings the standard Athlon 64, which was
single channel, into the dual channel arena also. Just a little confusing,
but there will be 3 boards for a while. 754, 939, and 940. I would expect
754 to byte the dust first, but you never know in this game.

With AMD Sempron(Socket754) on its way, Socket 754 migh be around longer
than 940. Socket 939 performs not far behind 940 for le$$, also unregistered
memory is cheaper than registered.

I doubt Socket 940 is going away any time soon for SMP machines. It costs a
huge amount of money to develop a 2-way, let alone a 4-way, motherboard
mainly due to all sorts of subtle timing and routing issues. If AMD dumped
940, then it'd be left without 2-way boards for at least a year, and 4-way
boards for probably close to 2 years, judging by the amount of time taken
for socket 940 boards to appear. This would be commercial suicide for AMD,
who is trying to get into the server (ie: SMP) market. It's also probably
the reason why AMD is not ruling out dual-cores on socket 940, as it's
unlikely to have established 2- or 4-way boards by the time dualcores come
out (2nd half 2005 by the roadmaps).

But in any case, this is irrelevant to the point made by Wes. The FX series
is not SMP capable, nor is the A64 series. The only CPUs which are SMP
capable are the 2xx or 8xx Opterons, which haven't appeared in socket 939
forms yet. This is decided by fuses set by AMD inside the core, so it's
impossible to change a FX into an Opteron (a la the XP -> MP L5
modification). Neither is it possible for chipsets/boards to override these
settings. Supposedly Opterons are supposed to come in 939 form eventually,
but the introduction date is AFAIK unknown.

If you want some 64bit dual action check out Iwill's board.
http://www.iwill.net/whats_new/SeeMore.asp?vID=84
Looks like it will be for Amd 64 what the Mpx2 was for Amd 32.
I have the Mpx2 and it was the ultimate in mainboards for Amd 32 Smp.

I don't think dual A64's will take off to anywhere near the same extent as
dual A32's, solely for the reason of price. Here's a comparison of dual
modded 2500's vs dual 240's ($NZ prices):

Dual A32 (pretty much my current setup):
CPUs 145 x2 (XP2500 x2)
HSF 50 x2 (TT Silent Boost x2)
M/B 430 (Gigabyte or MSI)
Ram 140 (1x512mb generic PC2700 non-reg)
------------
Total 960

Dual A64:
CPUs 420 x2 (240 x2)
HSF 50 x2 (TT Silent Boost K8 x2)
M/B 580 (Tyan S2875ANRF, only board under $1k)
Ram 160 x2 (2x256mb generic PC3200 ecc reg)
------------
Total 2420

For a rough comparison, wages are about the same in NZ and the US without
taking into account the exchange rate (ie: a $NZ30k/yr job here is a
$US30k/yr job in the US).

For a board that has dimms for each CPU, you're looking at another ~400 on
the board cost, plus another 320 for extra RAM (add anouther 140 to the A32
setup to bring it to 1gb as well). So you'll end up with ~2940 for the dual
240's, vs ~1100 for the dual A32 system. Certainly, the A64 system is more
powerful, but not so much more powerful that it warrents costing nearly
three times as much. Using the rough price-halves-every-18-months rule, a
*dual 240* system isn't going to get to my definition of affordable (using
the A32 point as being barely affordable) for another 2 years, ie: mid 2006,
or about when the K9's start hitting the shelves.

To become even a vaugely viable option for me, the CPU costs have to come
down a lot. The cost of the two 240s alone is about the same as the cost of
the entire dual A32 upgrade ...

A64!=Opteron

If the 939 platform is someday available for dual A64 it will kick ass

A64 == Opteron if you want anything but uniprocessor. Essentially the same
as with P4's and Xeons. And, to a lesser extent, XP's and MPs. Straight XP's
are incapable of doing SMP, but the disabled circuitry can be re-enabled by
rejoining the 4th L5. Only Opterons have the necessary HT links (enabled) to
do SMP, and that's the way it's staying, unless someone figures out how to
re-enable the links (very unlikely). Originally, there were dual-CPU capable
Clawhammers roadmapped in "below" the Opteron 2xx series, but these were
dropped before the first x86 CPU was ever released.

Even Celerons can do MP, it´s all about having a mainboard that supports
it...
My old BP6 with bx chipset and 2x533 Celeron was the best bord I ever had.
The VP6 can do MP new Celerons

Sort of ... The only Celerons that could do SMP are the Mendocino Celerons.
Try dropping a couple of Coppermine Celerons into a board. They won't do
SMP. SOME celerons can do MP, but not all. Neither the Coppermine or
Tualatin Celerons can do SMP.

Back in the Good Old Days, SMP used to be entirely dependant on the board.
This was because 486's and the like had no SMP capability build in (save for
the #LOCK pin). All the SMP stuff was done in chipsets. ServerWorks or
whoever would spends a few million dollars designing a chipset that could
run multiple 486's, and then sell it in small quantities at large prices.
This all changed with the Pentium (IIRC), which actually had some built-in
support for SMP configurations. The main part was the APIC, which suported
interprocessor interrupts, among other things. So at this point, the chipset
makers could do away with a lot of the complex stuff that used to be in the
chipset, and use the on-CPU features instead. This then gave Intel/AMD the
capability to produce SMP capable or incapable CPUs, as if these new bits
weren't enabled, then the CPU could not do SMP (as there was little point in
a chipset maker adding this stuff to their chipset).

AFAIK, the first CPUs to suffer this fate were the Coppermine Celerons. All
CPUs prior to that could do SMP, regardless of what Intel sold them as.
Because the chipsets nowadays rely on SMP support from the CPU, there's no
way for a "SMP-disabled" CPU to do SMP. The exact same thing applies in the
AMD camp, though with the A32's you could re-enable this support.

On the A64 front, the Clawhammer has 2P capability built into it (but the
required HT links and actual SMP capability are not enabled). The Opteron
has 8-way (possibly more) capability built in, and how much is enabled
depends on how much you pay. I haven't heard anything about the SMP
capability or otherwise of the Newcastle or Sempron cores.

Sure, ServerWorks et al COULD come up with a chipset that enabled
SMP-disabled A64's to do SMP by doing all the stuff that's normally done in
the CPU in their chipset. However, the price point would be (significantly)
above current Opteron chipset prices, so would make no financial sense. So
don't get your hopes up.

Umm, no it can't. The VP6 can't do ANY Celerons in SMP, Mendocino or
otherwise (google for "VP6 celerons").

Now that makes sense to me, thanks for the explanation!

With respect to dual Semprons:

http://www.theinquirer.net/?article=17287 says "you can plug Semprons
into MP boards and generally speaking, they will work."

It does not specifically say that dual Semprons work in an Athlon MP
board, but there is no technical reason that the Sempron could not
have all the SMP capabilities of the Athlon MP.

Of course, there are currently no MP boards with 167 MHz FSB, but that
is another matter.

I always thought that a dual Athlon MP system would outperform an
Athlon 64 or FX system, in SMP enabled applications, but I do not
have any evidence. And you can probably pick up a pair of MPs and a
board for less $ than a FX and a board. The only problem is that it
would be obsolete next year. But, all current motherboards will be
obsolete next year, when the dual core chips arrive. Perhaps we have
to realize that every CPU upgrade also requires a new motherboard
(and new memory).
