RAM for P5P800?

[Daniel Mandic]

The EE, I mentioned in my last posting is not a 478, as I suggested.
It´s a 775 Socket.

So I stucked to a i865PE, ASUS P5P-800 SE.
GfX we have is 8x AGP.



What is the fastest RAM available?
2-2-2?
We decided yet, using two RAM modules for a total of 1GB.
Dual-Channel....
CPU is iP4 EE, 3.73GHz, FSB1066, Socket 775, 2nd-Level Cache 2048KB
(150W )

I would slow down a bit and do more research.

The P5P800 is FSB800. Try typing "P5P800" in the search box on
the CPUSupport web page:

http://support.asus.com.tw/cpusupport/cpusupport.aspx?SLanguage=en-us

I don't know what would happen if you plug the 3.73Ghz into the
P5P800. Your processor is FSB1066, and that would be a 33% overclock
for the 865PE Northbridge. The processor may start at FSB400 (it
really depends on what the clockgen chip does with a 000 BSEL code)
and you might have to use the CPU clock adjustment, to try to get
closer to FSB1066.

The thing is, boards using the 865PE see video artifacts on their
AGP video card when running a high overclock. In order to run your
new processor at its rated speed, you would be running the
Northbridge at 266MHz instead of 200MHz. You can see a variety
of experiences here, with the 865PE Northbridge, and various
RAM ratios.

If you use the CPU search in the middle of the Asus CPUSupport web
page, it returns this for Pentium 4 3.73GHz Extreme Edition FSB1066
LGA775. As far as I know, these are all PCI Express motherboards.
One of these boards would be a better for use with your FSB1066
processor.

Motherboard Since PCB Since BIOS

P5AD2-E Deluxe ALL 0302
P5AD2-E Premium ALL 1005
P5LD2 ALL ALL
P5LD2 Deluxe ALL ALL
P5LD2-V ALL 0304
P5LD2-VM ALL 0128
P5ND2-SLI ALL ALL
P5ND2-SLI Deluxe ALL ALL
P5WD2 ALL ALL
P5WD2 Premium ALL ALL

The P5P800 is listed as working with a 3.4GHz Extreme Edition.
That has a family code of 0F25, and the chip is a Gallatin 0.13u
with 2MB cache. Stepping M0. And FSB800.

http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7RR

This is your processor. It has family code 0F43. It is 90nm, so
it is not a Gallatin. Tomshardware lists is as Prescott. It has
a multiplier of 14X (3.73/0.266=14) and if run at FSB800, would
look like a 2.8GHz Prescott with 2MB L3 cache.

http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7Z4

Here is an article benchmarking your new processor.

http://www.behardware.com/articles/551-3/intel-pentium-4-660-and-ee-3-73-ghz.html

The easiest way to use your new processor, is to use one of the
motherboards in the list above. These motherboards use PCI Express
video cards, and I think they all use DDR2 memory. In order to
reuse your AGP 8X video card, you really need a different processor
to work with.

This will require some careful thought on your part, so that you
will not end up with incompatible hardware. PCI Express and DDR2
are the current Intel technologies, and selecting the most capable
Intel board will best prepare you for whatever the future offers.

You could, of course, sell your nice processor on Ebay, and then
buy a set of hardware you are happy with. If your processor happened
to be an ES (Engineering sample, with unlocked multiplier), then
there would be fewer issues to being able to use the processor.

Don´t worry, I have time....

The P5P800 is FSB800. Try typing "P5P800" in the search box on
the CPUSupport web page:

http://support.asus.com.tw/cpusupport/cpusupport.aspx?SLanguage=en-us

Well, good that you mention. So far as I understood is the i865PE not
capable of doing 1066MHz FSB.

But, I stumbled upon this....

http://www.asus.com.tw/products4.aspx?l1=3&l2=11&l3=26&model=629&modelme
nu=1


there it reads: The P5P800 SE supports the latest Pentium 4 CPU from
Intel in LGA775 package. With 1066/ 800/ 533MHz FSB, Hyper-Threading
Technology and core-speeds up to 3.8GHz.
Hmmm....

If this is really true what I found, then we have no problems....
The GfX is already bought. It´s a GeForce Ultra 6800 AGP8X
(watercooled). I am pretty sure he won´t give it up.

I don't know what would happen if you plug the 3.73Ghz into the
P5P800. Your processor is FSB1066, and that would be a 33% overclock

and you might have to use the CPU clock adjustment, to try to get

Yeah, it (iEE) could work with 200MHz, at least. I am sure, that it
would be also a fast machine.

AGP video card when running a high overclock. In order to run your
new processor at its rated speed, you would be running the

OCing is no thema.

Well, as I said the GfX is the limiting part.

I am quite sure he decided for a iEE (actually a HyperThreaded 3.73GHz
iP4EE with 1066MHz FSB, actually 266MHz!!!). I tried to suggest him a
Pentium M system.

That is an amazing find. I cannot see "P5P800 SE" listed for
sale anywhere. It is not on the download page. And the claims
on that web page are pretty amazing. Running a dual core on
a 865PE ? I went looking for a downloadable user manual, but
cannot find one in the usual places. I hope the board really
exists.

OCing is no thema.

But I don't think you got my point. The thing is, if the 865PE
is run with 266MHz FSB, the video output from the AGP video card
develops artifacts, dots are visible that should not be there.
This newly designed board had better have a fix for that problem,
or no user of a FSB1066 processor is going to be very happy. And
the 865PE chip will not be "new and improved", because Intel
will be in the process of discontinuing production at some point.

Before you buy the board, see if you can find a review of the
P5P800 SE. I'm not sure this board is shipping yet.

How in the world did you find that web page in the first place ?

Do you mean the www.asus.com.tw homepage?



You said well. There is no P5P800SE listed to buy

But I found an Asrock 775i65PE which seems to be fit, supporting the EE
up to 3.8GHZ. It´s also a i865PH Chipset.
What would you say?
Slightly OT, so far I know is Asrock the smaller ASUS, or so....

I was trying to find it from a motherboard listing.

I downloaded the manual, and the only strange thing, is the
memory ratios offered.

FSB800 DDR400, DDR320, DDR266 (1:1, 5:4, 3:2 ratio)
FSB1066 DDR400 4:3 ?

It looks like they are claiming the 865PE has a 4:3 divider
available ? (The Intel datasheets do not declare all the
allowed values, so it is hard to say just what ratios are
in the chip. I don't understand why some of the other
ratios could not be used with the FSB1066, unless it has
to do with taming the AGP artifact problem.)

I guess you'll be buying ordinary DDR400
memory, if you buy the Asrock board to go with your
3.73GHz processor.

I saw some info in Russian, but could not translate it.

Normally, I would suggest him: To use the RAM (already bought, 2xDDR400
2225) at QP 800 =200MHz FSB. A nice clock (probably 222) setting. And
having 3GHz Extreme Edition. I am pretty sure this is fast. My 1.083Ghz
P3-S can drive nearly all games, GeForce4 in, of course. Without going
to 133MHz FSB.
His setup with the GeForce 6800 Ultra and the EE, whew... must be
faster!?
