This is being built for Photo and video editing, not a gaming machine,
and I need a lot of memory so I can do my thing quickly hence the 8
gigs. I'm working on a box with 4 gigs now and it just isn't quite
enough given the size of graphics files I'm working with. And because
of the limited number of PCI slots on the boards these days, I don't
know if I can have an add on serial port card. I know that I want one
slot for a scsi adapter and could easily find something else to fill
the other slot with like a firewire card. I've been thinking of the
x38 chipset, but am I really future proofing a computer, or will I
ultimately be buying a new board in 3 or 4 yrs because other
technology has changed so dramatically that a new board instead of a
new processor is going to make the difference performance wise? What
is your opinion of the P5E WS board? I believe that also has a serial
port and is X38? Thanks very much for the reply.

I can promise you, you'll be buying a new board in 3 or 4 years time.
Things like CSI and integrating the memory controller on the processor,
will help change the socket yet again. (And LGA775 has been around for
a while already, so is already an old socket.) It'll be interesting
to see, if CSI trickles down to the desktop or not.

It is part of Intel's business plan to:

1) Crush all chipset maker opposition (VIA is already out of the picture,
as I haven't seen anything from them recently. Still waiting to see
how long Nvidia can stand the heat.)
2) Get people to buy a new motherboard every time, so Intel gets profit
from the processor, and profit from the chipset.

At the 8 GB level, I might consider four sticks with ECC. But this
is your choice - it might not be possible to find ECC in "enthusiast"
grade memory, so finding something faster than DDR2-667 might be
more of a challenge.

The P5K WS uses a P35, which doesn't have ECC capability for the memory.
The X38 does have ECC capability, at least for DDR2 memory. Apparently,
X38 doesn't have ECC capability, if you find an X38 on a DDR3 motherboard
(verified on the Intel chipset comparison chart, as a missing feature).

Other options, would be to investigate server boards, ones with FBDIMMs.
AFAIK, the FBDIMM is fully protected (being intended for server boards),
but there would be a price premium for FBDIMM (fully buffered) memory.

If you don't want ECC, nobody is forcing you.

OK, try this one for size. P5E WS uses X38. By checking the actual
motherboard manual, it mentions ECC support. For some reason, the
web site doesn't mention ECC. (Note that ECC support has been flaky
in the past - there have been boards, where the hardware should have
supported ECC, but the feature didn't work for end users. Which is
why you need every bit of encouragement you can find in that regard.
I consider the Asus user manual, to be the contract between company
and customer, so if a feature is listed there, it had better work.)

P5E WS - X38, 8GB DDR2 ECC, serial port (COM header on motherboard, no rear connector)
PCI-X slot.

Very little traffic in the forum yet, for that board. First posting Nov.16/07

You'll need a part like this, to use with the P5E WS, to get a
working serial port. PCcables part 07120 is AT-Everex and seems
to be the format used by a majority of modern Asus boards. You
can also buy a 07121 as well at the same time, just in case.
The 07121 is DTK wiring pattern, and is the alternate solution.
Some people try a DTK type instead, and the port doesn't work.
The AT-Everex should do the job. (If you're going to waste the
money on shipping, might as well get a few different products
for the parts bin.)

Hey Paul, thanks for the help. I'm going to go with the P5E WS and
take your advice and start with 4 gigs of ECC memoryt. I'd like to
get involved with a 64 bit OS, but since I don't have one, do you know
if the board will work with W2000 SP4? I only have an upgrade version
XP Pro but I really don't like it as much as W2k. Thanks again.
