Celeron 1.8ghz on new mobo

[Avg]

I fixed a HP running a 1.8ghz two weeks ago, and after that the owner was complaining of random shutdowns, when i came over I found out that the caps were blown on the mobo so the owner decided to replace it. The mobo along with the cpu are old and runs at 400FSB, so I decided to get a new mobo but the ones I want to get only support 800FSB or 533FSB no mention of 400FSB ones not even on their websites, so since i'm don't have much experience with Intel I decided to ask you guys if, lets say I got a mobo with a i865 chipset, would that run at 400FSB? Also I want something with dual channel and agp/pci lock, and the mobo must be micro ATX to fit inside the case.

these are some of the ones I'm looking at

this one is the cheapest and has good user reviews but it has sis chipset

This one has good user review and a via chipset

And this one although it costs a little and lacks agp unlike the others,
it does have a intel chipset and it seems to be the only one with dual channel capability

Can't remember if they made Northwood Celerons in the 1.8 speed, but I do know they made Willamettes. Unfortunately, the Willamettes won't work on an i865 chipset. So, first thing to do is find out which processor you have. Look to see what default vcore is listed. The Willamette will be something like 1.75v and the Northwood will probably be 1.525v. If you have a Northwood Celeron, they will work in i865 chipset mobos even if they don't specifically mention 400 bus support (I have personally done this).

If memory serves 1.8s are all Willys.

Wasn't all willys socket 423? Is there a way to check if it is willy or northwood from lookin at the chip? because I don't know if the computer will stay on long enought for me to run cpu-z to find out what core it has, and since it's an Hp I can't check the voltage in the bios.

No, there were lots of 478 Willamettes. All 1.3 and 1.4 P-4's were socket 423 though. But the rest of the Willies were either 423 or 478. I "think" all the Willamette Celerons were socket 478.

Edit: I just looked it up on the Intel spec finder and there were both 1.8 Willamette Celeron and 1.8A Northwood Celeron (both socket 478).

http://processorfinder.intel.comGood catch. Notice the 1.80A Celeron is a D1 stepping. This means it is a pretty recent occurance. When 1.8 Cellys were being sold they were all Willys, but it looks like Intel put out a batch of Northwood ones much later on. Chances are good these were rarely seen on the retail market and/or used for warranty replacements.

lol, im using one of those 1.5 gig willies in my MSI barebone rig i use for email =P definatly an s478

I was able to run cpu-z and it is indeed a s478 willy, in this case what chipsets can/should I use for it? It is currently running on i845g I think on a intel made mobo.

[larva]

i845 series chipsets are pretty good for this application. I still run one with a P4-2.4b and it's very suitable.

That being said, I cannot guarantee that all i865 boards will not work with a Willamette core. My understanding is that i865 does work fine with Willys, as long as the VRM logic used allows setting the core voltage as high as 1.75V. Most OCing-oriented i865 boards allow this, and as such could work.

But I also cannot promise that it will work on any given i865 product. I have not tested this combination and cannot rule out the possiblity of bios limitation on some boards that would prevent success. I do think there is a good chance that boards like the Abit IS7, AI7, or Asus P4P800 will work, but the proof would be trying it. Outside of these boards, i845 is about as good as it gets.

I bet you can find a Soyo P4-I845PE V1.0 board for really cheap. It is 845PE chipset, so eh needs a graphic card, no intergrated. It is an incredible board, my sister is currently using it with her 2.4B, which is oced from 133 to 175 FSB, power supply limitting. Board says it can handle well over 200FSB and volts go all the way to 1.8.

there are quite a few at Newegg that are 478 & support 400 FSB-

micro atx 478 mobos-

yeah, I was looking at all those boards but the ones I liked had only had 800/533FSB on it. In any case I was over at the asus site looking at the P4P800-VM board and according to them it supports my processor although it didn't allow me to choose between northwood and willy so I'm going to look at the bios if the voltage is high enough and call them on monday to make sure. I was to get a mobo that if the owener wants she is able to upgrade it.
