what does that 'A' after 'P4 1.6A' mean?

[andylawcc]

is it the Northwood 478 version?
and is it only available in 1.6, 1.8, 2.0 and up, while 1.7 and 1.9 are Williamette 423??

 

[Wingznut]

Correct, and correct.

The "A" means it's a Northwood core built at .13mu and 512K L2 Cache. They run at 400 or 533Mhz.

Edit: Had to get my numbers straight

Hehe, you mean the FSB is at 400MHz or 533MHz. Honest mistake...what with 512 being in your head from the L2 cache.

sweet, thanks for quick replies..

so is there anyway that I could identify/differentiate the 1.6, 1.8, and 2.0 Willamette from the Northwood one? I mean, the Willamette also has 478-pin version right (someone just told me that); Do I need to identify them with the Processor codes (like "SL35D" for the Celeron366... OMG, I still remebered it! I sanded that mofo down) or there's an easier way?

Like they were saying the Northwood will have 512k cache and the Willamette will have 256k cache.

The Northwood procs have the "A" while the Willamettes do not. Northwoods are only 478-pin while Willamettes were both 423- or 478-pin. All Intel P4s over 2.0Ghz (2.0A and up) are Northwoods. All Intel P4s over 2.26Ghz run on the 533Mhz FSB for the most part.

ack, problem solved,
I just pay a few bucks more and get the proc from a reputatable merchant.

I was paranoid coz I was going to buy a P4 1.6A and worry about if they sell my the Willy instead.


Newegg is my new friend.

You shoulda got a 1.8A for a few bucks less

I am currently running a P4 2.0A on an ASUS P4B266. I spent around $450 for the combination in mid-January (both bought from newegg). If were in your shoes, I'd get a P4 1.8A for $164 or a P4 2.26 for $269 depending on my budget and how "future-proof" I wanted my system. More and more Intel stuff will probably be designed for the 533Mhz FSB.

ack, I meant, "I will a few bucks more...."
I didn't buy it yet, but I would. since I am building this for my friend, i am waiting for his approval.

 

[andylawcc]

okay, thanks GTaudiophile,
my friend doesn't want to overclock, so I will suggest him get the 533 FSB ones instead.

If you do go the 533 route, make sure the mobo supports that FSB too. I'd look at Intel or SiS chipsets.

It really means they kick Ass. 1.6Asskicker.

God I need help.

???? I thought all chipset supports 533fsb.
