Exterior difference Northwood/prescott

jdfrye · 01-27-05, 09:41 AM

I have bought a 2.8 Northwood on eBay and am wondering how you can tell the difference between the prescott and the northwood by just looking at them. Is there any physical differences? any way to look up the number printed on them on the internet. and if so which number will give me that info. i ask since my board will only accept the northwood

If you can read what is printed on the top of the CPU, then yes we can tell a lot about it. Here is my 3.2C:

3.20GHZ/512/800
SL792 Malay
L336F401

1st line: CPU clock speed/cache/system bus speed
2nd line: s-spec code and country of origin
3rd line: batch code

The first line of a Northwood 2.8C will be 2.80GHZ/512/800 and a Prescott 2.8E will be 2.80GHZ/1M/800. Also, you can look up the s-spec code on the Intel website.

that link you gave says your board supports pressies up to 3.4

According to that link, the 2.8 you bought needs to say "2.80GHZ/512/533" Your mobo doesn't support the 800GHz fsb 2.8 Northwood procs. It only supports the 533fsb 2.8 Northwood procs.

Boards only a 533Mhz system. Doesn't look like it supports Hyperthreading even. As said above the max CPU you can put in it is a Northwood 2.8 w/ 533Mhz FSB.

jdfrye · 01-27-05, 05:05 PM

heres the CPU that I bought.
I was hoping that there was a way to MAKE sure it was a Northwood when I got it before installing it.. dont know why but the Nothwoods were going for more money and i seemed to escape with this one at a good price. guess it was since i won the item at 3:00am in the morning

That one will work on your mobo because it is a "FSB: 533"

But heres why i posted in the first place.. i see that there are Prescott 533 fsb running at 2.8ghz. which will not work on my board
I was worried that i would get bambooziled with a prescott. which brings me to my first question.. when i get the chip in my hand,, is the a way to look at it and tell its a northwood chip

Pentium 4 Prescott 2.8G 533 21 NO
Pentium 4 Northwood 2.8G 533 21 OK

From your link ~ this line indicates it is not a Prescott. It is a Northwood 2.8 533fsb. It is on the approved list from the link in your first post.

batboy · 01-27-05, 05:36 PM

Yes. Look at the amount of cache printed on the processor... 512k=Northwood... 1M=Prescott. Like I said earlier, there will be a s-spec code that you can look up too. According to that auction, it's the right 0.13Micron, the right vcore, and the right L2 cache for a Northwood.

Model: Intel Pentium 4 2.80GHZ

Operating Frequency: 2.80GHZ
