Archived from groups: alt>comp>periphs>mainboard>asus (more info?)

I'm in the process of putting this board, P5K WS, together and want to
buy all 8 gigs for the board now. I'm checking Crucial and Mushkin,
any suggestions as to speed and brand? Crucial has a nice chart that
suggests the memory modules, and two speeds were listed, 5300 and
6400. How much faster will the 6400 be in terms of actually
perceiving the increase in speed? I'm also thinking of the Core 2 Duo
E6850 Conroe 3.0GHz 4M shared L2 Cache. Would that be a good choice?
I've done a little research but probably not enough to make a
thoroughly educated guess in picking the best processor. I picked the
P5K because it has a serial port and I need one for an old Wacom
tablet, and it appears to be pretty stable with 8 gigs of memory.
Thanks

8GB is a lot of memory. The more memory, the more chance for an
error to creep in. Is an error free memory extremely important,
or is this just a gaming machine, where a crash or other fault
just means a reboot ?

It is possible to get ECC protection for memory products, but
this requires chipset and motherboard support. It skews the whole
selection process for motherboards. So it is not something to be
taken lightly.

It is pretty hard to guess about the processor as well. There
are dual core and quad cores, at prices stretching from the
$280 level, to $1345. What level of performance do you really
need ? What kind of tasks do you carry out ? A popular processor
with gamers, is the Q6600, a quad at 2.4GHz that easily overclocks
to 3GHz (G0 stepping is best). The E6850 is about the same
price as the Q6600.

I guess I'm trying to figure out whether you really need a
"workstation" or "server" class motherboard, or whether
your application looks more like a desktop. Some Asus motherboards
don't have a serial port on the back, but they do have a 20 pin
header for connection of a serial port bracket. It is also possible
to get PCI cards with serial ports on them, so a solution can be
achieved that way as well.

A motherboard like the Maximus Formula, with X38 chipset and
support for DDR2 memory with ECC protection, is the basis of a
good computing solution. It doesn't have a PCI-X slot, but does
have two large PCI Express slots. There is no serial port. So
that would be an example of a board covering computing requirements -
you can even use a new 45nm processor if you want (this one is
a 3GHz quad, a lot more money than the Q6600, but doesn't require
overclocking to get to 3GHz):

Asus has a CPU Support page, where you can look up what boards
can support a given processor:

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.

http://en.wikipedia.org/wiki/Nehalem_%28microarchitecture%29
http://en.wikipedia.org/wiki/Intel_QuickPath_Interconnect

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.

http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=3C36D7E0A5CA7304

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
http://vip.asus.com/forum/topic.aspx?board_id=1&model=P5E+WS+Professio...&SLangu

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.)

I went to the local discount pc supplies shop yesterday with the intention
of buying a P5K series motherboard to build a Christmas present for one of
my sons.
Unfortunately my timing was off by a couple of days because they only had
integrated video cheaper versions left. The board I wanted is now
discontinued.

Additionally the premium quality P5E boards aren't readily available here,
yet, so my choice on the day was limited to a plain vanilla P5E.
Anyway I grabbed that board along with a case, 550W power-supply, 4Gigs RAM,
and Intel Q6600 cpu.
When I got home I researched the board that I had bought.
Summarising the differences over previous series.
It uses an X38 chipset along with the older ICH9R Southbridge.
It supports crossfire at x16 for both slots.
Supports PCI Express 2.0 for graphics.
X38 memory controller supports DDR2 as well as DDR3 SDRAM
Official support of 45nm processors.
The X38 Northbridge consumes more power.

My vanilla board uses a JMicron controller for PATA support and has only one
LAN controller while the WS version you are considering uses a Marvell
controller for PATA and external SATA support. It also includes 2 LAN.
Both boards include 2 firewire ports (one at the back and one onboard). I
myself always buy cases that include a front firewire connection as I use it
so much.
The WS version has a couple of pci slots and a pci-x slot both of which can
support SCSI cards.
It also includes an onboard serial/com port but I doubt that they supply a
bracket.

I had a look at some reviews of the P5E and performance wise it seems to be
on par with previous P35 and i975 boards.
It's probably a transition solution, waiting until the price of DDR3 RAM
comes down.
It would be interesting to see test results of say the WS version using low
latency DDR2 RAM and the other WS version that supports DDR3 RAM. I wonder
if there would be any real difference in speeds.

As far as future proofing goes. I have read that future Intel cpu's will
bring the memory controller on-die so that will mean a whole new motherboard
probably with DDR3 RAM by then.

Are you sure you fully understand the situation? You are certain it's
the amount of memory that slows you down? And you understand that a
32-bit application is always limited to 4 GB and even that requires
you run it in a 64-bit OS or one that supports PAE like Windows
Server?

Photoshop CS3 is still a 32-bit app. With ordinary Windows XP you have
2 GB per process maximum, 3 GB with a kludge that can cause stability
problems, same thing with the PAE support. On the other hand, driver
support in 64-bit Windows XP and Vista is poor.

With all this in mind, the best situation is that you have 4 GB RAM
for the application and most of the rest for disk cache. It'll
certainly help, if you're actually memory limited now.

Apparently there are PCI Express x1 cards for serial too, so maybe
that helps.

"Photoshop CS2 is a 32-bit application. When it runs on a 32-bit
operating system, such as Windows 2000, Windows XP Professional, and
Mac OS v10.2.8, it can access the first 2 GB of RAM on the computer.
The operating system uses some of this RAM, so the Photoshop Memory
Usage preference displays only a maximum of 1.6 or 1.7 GB of total
available RAM. If you are running Windows XP Professional with Service
Pack 2, you can set the 3 GB switch in the boot.ini file, which allows
Photoshop to use up to 3 GB of RAM.

Important: The 3GB switch is a Microsoft switch and may not work with
all computers. Contact Microsoft for instructions before you set the 3
GB switch, and for troubleshooting the switch. You can search on the
Microsoft support page for 3gb for information on this switch.

When you run Photoshop CS2 on a computer with a 64-bit processor (such
as a G5, Intel Xeon processor with EM64T, AMD Athlon 64, or Opteron
processor), and running a 64-bit version of the operating system (Mac
OS v10.3 or higher, Windows XP Professional x64 Edition), that has 4
GB or more of RAM, Photoshop will use 3 GB for it's image data. You
can see the actual amount of RAM Photoshop can use in the Maximum Used
By Photoshop number when you set the Maximum Used by Photoshop slider
in the Memory & Image Cache preference to 100%. The RAM above the 100%
used by Photoshop, which is from approximately 3 GB to 3.7 GB, can be
used directly by Photoshop plug-ins (some plug-ins need large chunks
of contiguous RAM), filters, actions, etc. If you have more than 4 GB
(to 6 GB (Windows) or 8 GB (Mac OS)), the RAM above 4 GB is used by
the operating system as a cache for the Photoshop scratch disk data.
Data that previously was written directly to the hard disk by
Photoshop, is now cached in this high RAM before being written to the
hard disk by the operating system. If you are working with files large
enough to take advantage of these extra 2 GB of RAM, the RAM cache can
speed performance of Photoshop. "

I found that on the Adobe sight. So what I'm understanding is that
Photoshop can run on a 64 bit operating system which is what I'm
interested in and that it can actually take advantage of more than 4
gigs of memory

I appreciate your reply as I am now rethinking what motherboard to
buy, whether to use ECC memory, how much memory to buy, etc.

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.

Click "Drivers" link on the horizontal bar.

http://support.asus.com/download/download.aspx?SLanguage=en-us&model=P...20WS%20

After looking at the drivers, it looks like perhaps AHCI or RAID
are not supported on Win2K. The chipset INF and the audio drivers
do include Win2K support (but I had to look inside the INF driver
download, to see mention of Win2K support. I looked at the LAN
driver, but it is actually difficult to tell what OSes are supported
in there. One of the README files in a folder mentions Win2K, so
I suspect the Marvell LAN is OK as well.

I'd say the days of perfectly trouble free Win2K support may be
over. I don't expect you'll have a problem getting the machine
to run (vanilla boot disk on the Southbridge, default Microsoft
driver should work), but some features may not have all the support
needed. That means doing a lot more investigating, before you buy.
(I'm a Win2K user, and I don't see a particular reason
why it is so hard to make a Win2K version.)

Paul

After reading your post and doing a little research on 64 bit XP I
don't think it's going to work for me; it's too expensive a conversion
for the amount of upside right now and not greatly supported as you
said. So I think what I'll do is buy the board and buy two 2 gig
modules and leave the others empty so they can be upgraded if I did
make the OS change in the future. Thanks
