Trying to find a P4 CPU, having trouble

[Vigilante]

Hey, I've checked my favorite vendors but can't seem to find a Pentium 4 Northwood CPU. 800fsb and 2.8ghz.

I've got about a year and a half old HP here. The mobo is an ASUS P4SD-LA, I found a description which says it supports up to a 3.4ghz Northwood CPU at 400/533/800 bus. Doesn't say Prescott support.
The chip that is in it, which is dead, is a 2.8ghz 800fsb. I assume it must be Northwood.

But I'm having trouble finding a replacement model for insurance purposes. Zipzoomfly has 800fsb Northwood but not as high as 2.8. Newegg has nothing. Froogle search turns up zilch.

So what happened? Did little aliens abduct the earth's supply of 2.8ghz Northwood CPUs?
Anybody know of a reputable vendor with this CPU non-oem? Also is there a way to see what core this CPU is? By a numbering or lettering or some such?

thx

This was all I could find.

I don't know anything about the outfit, but they have the "bbb" symbol on the page. .

I assume you couldn't use a prescott core? They're a lot easier to find.

Edit: Hey just found this, check it out.

Under cpu support it says northwood/prescott, so maybe...it'd work?
I guess that's the same board.

Your first link, I don't see where it says Northwood, unless I'm missing it. But doesn't say Prescott either I suppose.

The mobo link is for "cobra", I had found one also:
http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&docname=c00022505
But that says for "stingray". So the Cobra is Prescott compatible and the Stingray is not. Well wouldn't you know it, they don't print that info either. What a surprise!

Now I gotta find out what's the difference. Man I hope it's Prescott compatible, that would make life easier.

thx

Just foud, one of the little chips on the mobo has this printed on it:

C1
STINB
3.11

Wonder if "STINB" might be STINgray somehow? lol

The link of the cpu I listed, this one,
http://www.4reseller.com/MfrListingDescription.jsp?ListId=FR4116
is northwood.

It has 512kb l2 cache, prescott's have 1mb(except celeron prescotts, which IIRC are 256kb).
It also doesn't support sse3, which prescott does.
It's based on the 0.13micron process, and I think prescott is based on 90nm.

I remember back when they first came out with prescott and people had issues trying to get it to work on their board, it took a while 'till things got sorted out.

That's strange that one board model can have 2 versions, or maybe it's a codename for a revision, like instead of having rev 1, they have stingray, and instead of rev 2 they have cobra, etc.

I wonder if prescott support has to do with bios support or hardware support in this case.

Okay, cool.
Well the parts have been priced out and the person is dealing with insurance to get the money. I advised her not to fix the stupid thing anyway, but get a customer built made, then we won't have to worry about this proprietary crap.

And on another topic, speaking of proprietary. Wouldn't you think that manufacturers could SAVE money by NOT customizing their hardware? Then they don't need all the extra labor, manufacturing plants, etc. etc. And yet somehow by sort of making their own parts, they save more money then just buying generic parts en masse. But anyhoo

thx for the info

I agree, proprietary stuff is annoying, but I think they make money on it.
Like if a system has a psu that can only be bought by dell(for example), then if it goes bad, dell is almost guaranteed to get more money if it's fixed(and they can charge whatever they like). I think dell charges like $200 for a replacement motherboard for their low end systems, which is insane, it's like a board you could buy for $40 if you'd buy from the 'egg.


BTW: What happened to the system you're working on? Lightning? I don't know how else you'd get a fried cpu on an oem system(since they usually can't be overclocked), usually cpu's don't just go bad, unless they overheat, or get electricuted.
