Howdy group,

I'm considering buying either a P4P800-E Deluxe or a P4C800-E Deluxe mobo. In Australia the P4C800 is about $80 to $100 dearer than the P4P800. I'm not really sure just what are the differences between the 2 chipsets. From what I've read the 875P chipset supports ECC memory and has PAT enabled. However, I understand that "PAT" is enabled on the P4P800-E Deluxe. Is this true? If so, are there or what are the advantages buying the P4C800 mobo over the P4P800 mobo?

I intend to buy a P4 2.8Ghz Northwood core to start with and upgrade early next year to a faster P4 (if I can afford a faster P4 now I'll get one). Although I don't know much about over-clocking I'm going to 'have a go' once I get the PC working.

With this in mind I would like to know what brand/module memory to buy that works with either of these mobo's. I'm looking at buying 512mb CAS2 class (2 * 256mb). For example, one of my local computer stores has - 256mb Kingston HYPER-X PC-3500 433MHZ, CAS-2, 184-PIN DIMM DDR SDRAM (KHX3500-256) on "special" at the moment. Would this ram work OK? They also have some GEIL PC-3500 LL ram on special. Or is CAS2 memory an "over kill"? If so, what would you recommend?

Thanks very muchly
Barry...

The P4C800-E has the 875 Northbridge, and it has a private
bus interface called CSA, which connects directly to a Gigabit
Ethernet chip. Unless you have a Gigabit switch to connect
the computer to, or another computer with a Gigabit interface,
this is overkill. The idea is, the CSA has so much bandwidth
available, that the bus is not a bottleneck to the Ethernet
traffic. The Ethernet chip on the P4P800 will connect to
the PCI bus, like most other computers in the world, and the
small amount of Ethernet traffic normally used won't
affect the PCI bus significantly.

The P4C800 will have the advantage in the overclocking department.
There is a poll being conducted on the forums of Abxzone.com
about the P4P800 having video artifacts at high overclocks, so
go over there and read up on what frequencies are required to
cause problems. There are no problems with the P4P800 at
normal frequencies.

You can also search for your ram choices over there, and see
if anyone is using them.

Be careful with the Hyper-X. I just checked the web page, and
the old stuff KHX3500 is 2-3-3-7, while the newer stuff
KHX3500A is 2.5-3-3-7. It is possible the newer stuff is
using Hynix chips, and apparently the Hynix chips cannot do
CAS2 when used with an 875/865 based board. This is not a big
deal, as the diff between CAS2 and CAS2.5 is not that big.
(Corsair had to change their datasheets recently, from CAS2
to CAS2.5, so this is an industry wide issue with the Hynix
chips. But the Hynix chips were designed to go at high clock
speeds, and expect to find the Hynix chips used everywhere,
now that Winbond BH5 is all gone.)

http://www.valueram.com/datasheets/KHX3500_256.pdf
http://www.valueram.com/datasheets/KHX3500A_256.pdf

The two PC3500 products I looked at on the geilusa.com
site are 2.5-3-3-6, and I would guess they are Hynix
chips. (How else can you explain the 2.5 ?)

If you want this kind of memory, I would buy the KHX3500
if it is really CAS2. If you are as cheap as I am, then
CAS3 works quite nicely too :-)

This Intel memory guide has some info that applies to
both the 875 and 865, and may help explain a bit about
the operating modes of the chipsets.

ftp://download.intel.com/design/chip...s/25273001.pdf

For your overclocking experiments, you'll be using the
5:4 CPU:memory ratio, and according to www.cpudatabase.com,
should be able to reach 3.6GHz with a 2.8-C. That would
take FSB clock = 257MHz instead of the normal 200MHz,
memory setting "DDR333" (which is actually DDR320) to get
the 5:4 ratio, and memory actually running at
(257/200)*320 = 411MHz and well within the 433MHz rating of
the PC3500.

As far as I know, PAT only works at exactly stock frequencies.
When you overclock, PAT is disabled. There is a dangerous
BIOS hack for making it work at all frequencies, which
involves loading the BIOS boot block from another motherboard,
along with returning the normal BIOS to the rest of the flash
chip. This is a pretty extreme hack, for the little benefit
you would get running normal everyday applications.

Don't bother with "Turbo". Stick with adjusting the memory
settings manually, to stay safe. Oh, and check your Vdimm,
as high performance memory needs at least 2.6 or 2.7V to
work well.

Have fun,
Paul

And thank you as well. I am currently considering overclocking my 2.6C
on my Asus P4C800-E Deluxe and have no clue how to make it stable. I
had it up to 2.9 manually but it was crashing..

Paul,

Once again thanks very muchly for your earlier reply.

I spent several hours at Abxzone.com reading several very looooong threads on PC memory. To be honest, I don't understand a lot of what was written but it DID help somewhat.

I replying again since I'm about to buy the mobo, ram, graphics card, etc. etc. and I just want to know that I'm getting the right CPU/RAM combo for my needs.

To voice the bleeding obvious, I've got 2 choices : To OC or not to OC.

From what I read, if I want to OC then my best choice would be to buy a 2.4C P4 and the fastest memory I can afford. Particularly PC3700 or PC4000.

On the other hand, if I DON'T want to OC then buy the fastest P4 I can afford and "normal" PC3200 ram.

I also gathered that LL ram is far more important for a AMD XP than it is for a Intel P4.

Given my lack of knowledge of "all things OC'ing", I'll take the NO OC'ing option. I know it may not be difficult but I simply can't afford the chance that I might "burn" the CPU/ram/mobo by making a silly little mistake.

In your reply above you suggest that CAS3 ram is just fine. I presume your are referring to Kingston Valueram or similar.

However, after reading the threads at Abxzone.com I'm still not clear whether buying say, CORSAIR PC3200LL, will give me any better performance at standard FSB/etc. and even if it does, how much?

Thanks very muchly
Barry...

First off, if you want the last percentage point of performance,
I'm not the guy to ask. There are plenty of people on Abxzone
who sweat the details, and if you read enough of their tests,
you might get some good ideas as to what to do. (The only thing
I don't agree with, is running 2.5V memory at 3.3V. That is
like putting sugar in your gas tank...)

For a general overview, there is this article. While many people
will bemoan the fact that the article is published on Tom's, it
is better than nothing, and faster than reading 10,000 posts
on Abxzone.com.

http://www.tomshardware.com/motherbo...119/index.html

The thing about some of your overclocking choices, is they
cost money, and only work well if you use them for their
intended purpose. Take the "PC4000" memory, for example.
It excels at high memory clocks, and you are balancing the
25% improvement, going from DDR400 to DDR500, versus the
fact that the memory runs at 3-4-4-8 versus 2-3-2-6 or the
like. If you bought the PC4000, and didn't overclock, the
solution would be inferior to buying PC3200 memory (as
PC4000 doesn't magically become LL memory when the clock
runs slower). So, if you are "going for it", then you have
to stick with it.

If you buy PC3200 memory, you can run CPU:FSB at 1:1 for
stock frequency operation (FSB800 CPU and DDR400 dual
channel memory). Nothing is stressed. If you select the
5:4 ratio, you can do some core overclocking and extract
more performance from the processor than normal. The
FSB runs at FSB1000 when CPU clock is 250MHz and the
memory is still running at DDR400. So the combo of PC3200
LL memory and 875/865 available ratios, gives you some
options. (Also keep in mind, you have to select the
processor based on your ram strategy - a 2.8*1.25
overclock = 3.5GHz, which looks to be achievable
on the cpudatabase web site.)

If you had asked me this question maybe 4 months ago,
I'd have been telling you that PC4000 was the best
performance wise. But there are some dissenting voices
over on Abxzone right now, who are getting _almost_
as good results from using LL memory. This has left
me, to say the least, very confused :-)

I guess I would say, if you are happy to have a fast class
of machine, without splashing too much cash around, then
some ordinary CAS3 is good enough. Buy the PC3200LL if
you want some options, being aware that as a result,
you end up with a processor that runs at either 2.8GHz
or 3.5GHz. (Same ideas apply if you choose some middle
ground, like the PC3500. That would leave room for a
slightly higher top end, and might require better than
just air cooling for the processor.) Buy the PC4000 if
you plan to leave the processor at 3.5GHz all the time,
and have applications that are very memory intensive,
like Photoshop.

Keep in mind, that the improvement in memory bandwidth,
isn't reflected to the same degree in overall performance.
A 10% improvement in memory bandwidth might buy you 3%
shorter execution time in what you are doing. Exceptions
are Photoshop or other applications with a heavy emphasis
on memory - if you spend most of your time doing one
application only, then pick the solution that is best
for that one app.

As for "burning the mobo", the P4 has thermal throttling,
so isn't likely to disappear in a blaze of glory. My rule
of thumb is, you can overclock to at least the highest
frequency that the family runs at - the processor dice
are all the same, and are binned for operation at 2.8, 3.0,
3.2, 3.4 etc. So running at 3.5 isn't a big deal.

If you have to raise the voltage of a part significantly,
in order to have a stable overclock, that does imply an
extra stress. You do occasionally read of people who have
to back off on their overclock, because the processor
gets "tired", and I take this to be a speed fault caused
by electromigration. This is why I don't recommend just
randomly increasing the voltage. On the DDR DIMMs, 2.6
to 2.8 is probably not too hard on the DIMM, but higher
than that is asking for trouble, as some portions of the
circuitry in the DRAM is regulated by an internal voltage
regulator, and the extra voltage is just turned into
unnecessary heat (heat which in fact, slows the memory
down!). I think using a little common sense, you aren't
going to affect the 3 year practical life of the mobo
before upgrading again.

HTH,
Paul

The board/ram should be fine at a 7-10% overclock.

in BIOS
set everything to "default"
then
set pci/agp ratio to fixed 33/66 (or it changes w/clock speed)
set ram timing manually to 4 3 3 7 (slowest, you can change later)

turn off or disable onboard sound (if using a pci sound card)
turn off or disable onboard network card (if using seperate nic)

In general...a 10% overclock on a stable system won't need
any more than above, weak spot is usually either ram quality
or excess heat in case or on video card.

now up the cpu speed by a few numbers at a time..
eg...203...204...210. and try to be patient.
Even if you achieve 210..there is no guarantee the ram will
be stable under heavy cpu load inside the operating system.

then try again.

if necessary you may be able to up the ram voltage to 1.6v
(check manuf, and for posts using that specific ram type)
as some are a bit on the low side. be careful with any voltage
changes on any parts unless you really are experienced.

Paul,

Thanks for your reply.

I brought a P4C800-E Deluxe mobo and a GeXcube 9600Xt Extreme video card today.

On Tuesday when the PC shops open after Easter I'm going to buy a P4 3.0C, Corsair TWINX1024-3200LL memory, 2*120gb Hitachi 7K250 SATA HDD's, GlobalWin SAF450W PSU and a Plextor CD burner. I'll buy a Plextor SATA DVD burner in a few months. On Wednesday I'll start saving for my next PC upgrade in X years time!!!

The upgraded PC will "fly" compared to my existing PC running a PII 266Mhz, 128mb 66Mhz memory and 12gb of HD space.

Thanks muchly for your help
Barry...

Thanks for the help. I had gotten a pretty stable 2.9 with setting the
PCI/AGP ration to fixed 33/66, and fixed memory timings... got the FSB
up to about 220. I have 1 gig of Corsair XMS DDR PC-3200
(TWINX1024R-3200C2PT) Cas Latency: 2-3-3-6 is stock.


I think I crashed in UT2k because of I didn't mess with the memory
timings. Nor did I mess with the voltages. I understand UT games are
cpu intensive and that might have been why FarCry had no problems at
2.9, but the old Unreal Tournament 2003 choked.

ok, the corsair xms is nice ram...likely do 2.5 3 3 7 at 220 (10% o/c).

iirc that ram should goto about 250 but may need to set
ram speed from 400 speed to 320 speed (4/5 of bus speed).
remember it's ddr (double data rate so a 400 speed is 200mhz)
Mostly I might try togo as high as you can without any voltage
changes and the cpu/board heat/temp are fairly close to original.
I suspect 12-17% overclock should be stable w/o much effort.

hmm, yes ut2k and ut2003 are ram/cpu intensive,
I don't know/have the Far Cry...how is it?
