where to find Intel P4 Northwood 2.8Ghz 400FSB ?

[lordsmurf]

Any ideas?

I keep looking, not finding one.
Supposedly a 3.0Ghz 400FSB exists too, but not seen one to date.

This from the 478 socket Intel P4 list: http://support.intel.com/support/processors/pentium4/sb/CS-011987.htm

It looks like a 400Mhz FSB falls betwen the 2.6Ghz 400Mhz FSB models and the 2.8Ghz 533/800Mhz FSB CPUs. In one chart I saw they listed the 400 and the 533FSB model on the same line. Makes me wonder if it's either a 533 or a 800Mhz FSB underclocked for a certain application/motherboard? The 800FSB is really a 200Mhz FSB quad pumped to 800 anyway.

A couple months ago they were all over newegg. Looks like there are no Northwoods there now.

Socket 478 chips are becoming harder and harder to find just like socket a chips. I never remember seeing 400mhz FSB Socket 478 chips between 2.6-3.0. They were always either 533mhz or 800mhz. You could always install an 800mhz FSB and manually change the multiplier in the BIOS to run at 400mhz if that's what your board supports. I'm curious though, which board are you adding this to?

AH! Now we're getting somewhere. If you notice the article you linked to includes the words "defunct Socket 423". That article was written 1 1/2 years ago and it was a defunct socket then. Good luck finding one also to note the system that powers this uses RDRAM which for a 512MB stick it's more cost effective to buy a 64 bit chip and a Motherboard. Which 423 board do you have?

[smearbrick1]

I had a Dimension 8100 with a socket 423 processor (1.6 ghz PIV) and I upgraded it with a powerleap. It was ridiculously easy to do. The only limitation is I could only use socket 478 chips with an FSB of 400mhz. Not a problem though, I bumped it up to a 2.4. Unfortunately, like ROF said, the bigger problem was the RDRAM. After all was said and done, it was cheaper to part out the Dimension (got $500.00 total in all parts - not bad) and purchase a new PC. The RDRAM was like $250.00 for 512MB.

[lordsmurf]

I already own 1GB of RDRAM and have for a long time now. My system cannot be upgraded with anything more than a CPU, and it should do nicely. I'm maxed at 1TB HDD, 1GB RAM, and pretty much everything inside and outside is filled up.

A new system comparable to what I have now would run at least $500 or more, at minimum. This Powerleap setup would just be around $275 or so, for the new CPU and the new socket adapter.

I would require a new case, new RAM, new everything, if I decided to buy a new CPU and new motherboard. It's not at all cost effective, and the performance difference between these two options is somewhat negligible.

The raw power of a 2.8Ghz is the most important aspect to video, the FSB and HT are not as important. Helpful, but it's not like it's leaps and bounds different.

Not to mention I don't have the time to re-install software, and changing motherboards would require a fresh install of XP. Don't say otherwise, I have already tried that in the past, on another machine, it does not work correctly (and I see this problem mirrored online too, with others).

In the future, I may buy another computer, but not now. Just want to max out this system for now. We are "between generations" right now, in terms of CPU and OS, so I'll wait for the next generation of hardware/software before adding anything brand spankin' new.

If you are going with the Powerleap setup, good choice. I've had two and never had one issue with either of them.

[ROF]

I've only used the Slot Wonder from powerleap on several older systems. Never had any issues with them and always functioned exactly as marketed. A good solution towards upgrading an older system.

This thingy is extremely over clockable too. They don't make over clockable chip anymore !

[INFRATOM]

if Nortwood is out of stock then you have to go with Prescott it just runs hotter. When they get obsolete one has not to be picky. You can use Celeron they overclock better. Another thing if you are getting 800 MHZ FSB cheaper there is no reason to look for 400 FSB maybe you upgrade MB later . I bet some where you can buy a computer that MB is not working and you can buy the whole thing for the price of CPU or less. Is there a computer junk yard ?!! there must be.

ebay.

and 2.8GHz is the highest the 400fsb cpus ever went.

[edDV]

All current production Pentuim 4 and Celeron D products are either 533MHz, 800MHz or 1066MHz FSB.

Celeron mobile and Celeron M models are still 400MHz FSB.

Looks like used or obsolete stock markets are the only sources for 400MHz FSB Pentium 4.

Well I had decent success moving an existing win Xp to a new MB etc...Easiest way, Uninstall any Drivers that can uninstalled via the add/remove applet. Plug in a Promise controller card and make sure windows installs its drivers. Move the boot drive to the promise and test.

Move boot drive to new hardware including the promise card. Install new drivers for new hardware. move boot drive to MB controller and done. And of course most likely you'll also need to re-activate XP.

I've also seen move the drive, don't even try to boot, run the windows repair process and usually done too.

PowerLeap still sells new Intel P4 2.8GHz 400MHz FSB. You can get them for around $220.
