Help needed: Asus P4P800-SE & Celeron D 345

[SMcA]

Summary of my computer:

Asus P4P800-SE motherboard BIOS Version 1011
OCZ 2x512MB PC3200 Dual Channel DDR-RAM
ATI Radeon 9550 with 256MB VRAM
LG DVD+/-RW drive
Maxtor 250GB hard disk with 16MB cache

Right now I am using a Pentium M 1.4GHz overclocked to 1.82GHz (using Asus CT-479).

When I swap the processor with a Celeron D 345 3.06GHz, the system won't boot. I used a Zalman CNPS7000B-Cu HSF.

The processor works in a MachSpeed Matrix P4M800 motherboard. So the processor is good.

The Asus website says that the processor has been supported since BIOS 1007 (http://support.asus.com/cpusupport/cpus...spx?SLanguage=en-us&model=P4P800%20SE).

Has anybody come across a similar situation? I would appreciate any possible solutions.

And one more question: should I use the Celeron D instead of the Pentium M? Will I see lower performance from the Celeron D compared to the Pentium M?

I am asking because the Celeron D has a higher clock speed but only a quarter cache compared to the Pentium M.

Why do I want to do this? I want SSE3...

Did you try resetting the CMOS? Your board may have less of a problem recognizing the different CPU.

I'll try that, but I have used a P4 1.5GHz and P4 2.5GHz on this mobo and they work fine. I didn't have to reset the CMOS for them.

Well it should work. It's supported by the motherboard and by your bios version. What programs are you running that need SSE3? A pentium-M @1.8ghz is gonna be faster than a celeron-D @3ghz in about everything. My pentium-M @2.4ghz gave my P4 @3.82ghz some good competition, except video encoding and synthetics, or other SMP aware programs due to hyperthreading, which you celeron doesn't have.

I want to run <you know what> and it requires SSE3 for emulation. There was a way around that by using SSE2. The updated version needs SSE3 and PAE (Physical Address Extension). Do the S478 Celeron D's have PAE?

The other thing is that I use my computer is I use it as a DVR. I encode everything in WMV9 because using MPEG4 results in dropped frames. So I was wondering if a Celeron D would be faster than a Pentium M at encoding MPEG4. I guess a Pentium 4 would be the ideal solution on this mobo but I had a Celeron D lying around the house and I thought I could use it instead of investing in a processor I didn't need to buy.

"Do the S478 Celeron D's have PAE?"

Nope, none of the socket 478 chips have PAE(AKA EM64T).
And no, I don't know what you want to run. A dual core would be more ideal for video encoding, but you aren't gonna get that on socket478 either. The netburt architecture does tend to do well with video encoding, but you aren't gonna no which of the 2 is faster unless you try it. I think the pentium-m will have the edge over the celeron though.

PAE is not x64, at least according to Wikipedia (http://en.wikipedia.org/wiki/Physical_Address_Extension). I've heard from several sources that PAE has been in Intel chips since Pentium Pro (Pentium M - Banias is the exception). Anyways, I'll elaborate on my findings once I get the processor up and running.

By the way, I will definitely overclock the Celeron D as much as my hardware setup will allow.

Looks like you are correct, PAE is something differant. However it applies to using more than 4GB of ram..and socket 478 motherboards aren't going to support more than 4gb of ram. And windows 2000 and windows XP(at least the 32bit version) do not support more than 4gb of ram.

Resetting the CMOS didn't work :'(
