P4's--- A's, B's & Northwoods?

[Hyperlite26]

Hello, I was wondering about some things. A P4 2.0 is not a Northwood , A P4 2.0A is a Northwood?
I know by reading that the Northwood is a better chip. This is for Oc'ing purposes mainly? Also, what is the deal with a P4 "B" on it like a P4 2.4B compared to a P4 2.4, just the 533 vs 400 MHZ FSB?

I wanted to go w\ a P4 2.26 as it has the 533mhz FSB and I cant afford a 2.4 or 2.4B so is there such a thing as a 2.26A, or does the 2.26,2.4, 2.5 automatically mean they are Northwoods and\or have the 533mhz FSB? Thanks a bunch!😕

there are basically three different p4 chips out there in the market
one is willy...which is a smaller L2 cache die 256k, also it is in 0.18micron
second is northwood A's...which has 512k L2 cache die on chip, also 0.13micron, also with 400MHz bus system
third is the new northwood B's...which also has 512k L2 cache die as the A's chip, also 0.13micron, but with 533MHz bus system...
the only way to differential the three is to either look at the description carefully before purchase or by calling the vendor...
or if you had the chip already...just check with the serial on box...usually it will list the MHz and Cache size...ie xxx/533/512k...
2.26 is a B version i believe...it has a multiplier of 17 and bus 133MHz (533MHz quad)...hence 2.26GHz
and 2.4 has two version...make sure you check if it is a 400MHz quad bus or 533 quad bus
2.53 is also a B version...which has a multiplier of 19 and bus 133MHz (533 quad)
HTH 🙂 <--- thanks thugsrook for letting me know what that means

Esentially the A's and B's are all Northwoods. The difference being that the A's have high multiplier / low FSB (100/400) and the B's have low multipliers and high FSB (133/533).

If you get a mobo that can fix the PCI/AGP, and get high quality RAM, then a high FSB isn't really an issue and you should go for a 2.26B. You should be able to get close to 3Ghz with it, and you'll have the bonus of having a lovely high FSB 😀

A P4 with no letter designation or one that doesn't advertise the .13 micron manufacturing process is not a Northwood, do NOT buy one of these chips.

The A's (1.6a, 1.8a, etc) are Northwoods, .13 micron. These cpu's are rated to run on a 100 MHz front side bus at default speed. Buy one.

The B's are also Northwoods (.13 micron) that run at 133 MHz fsb. More expensive. Buy one.

HTH 🙂

Edit: SupermanCK / snow patrol, jeez, by the time I got done typing mine, you guys already posted! Sorry!

Cool guys, that helps alot! Hey Snow Patrol, regarding you reply and the pci\agp lock, I think I will go w\ the P4 2.26 on a Gigabyte GA-81Hxp & some Rambus 1066mhz RAM @ 512 total. Would go to a gig but can't afford to go a gig yet on the ram, prob later. 🙂

I don't see it say that it has that lock you are talking about, but I may have missed it. Link to see specs>>> null This would be a good combo?

Thx!
