What's the stock core voltage on Willamette P4s?

[Pharmdeity]

I am about to test/buy a used 1.8ghz P4 with 256 kb cache. I believe that makes it a willamette core processor. I want to set my bios ahead of time so I can just drop it into my motherboard, boot it up, and see if it's good. I just can't remember the voltage for these.

thanks

1.75v

If you have a socket 478 motherboard, I would forget the Williamette and try your luck with a mobile Celeron or perhaps a Celeron D if you motherboard supports Prescotts.

If you have socket 423 then your choices are pretty limited.

Damn i was miffed when i realised i had bought my first P4 on a socket that was going to die that quickly... Socket 754 was my next rig after that... :frown:

I agree, socket 478 has more life in it that 423 and by life i mean the capability to find parts, there will still be a ton of 478 parts floating around out there, socket 423 died a long time ago, and the parts you do find for it are for the most part low quality. Not to say there isnt anything good out there for it, but you would have an easier time with 478.

1.75v like rouge said.
What motherboard? Socket 423 or 478? The problem is that if it's 478, it won't neccessarily support your CPU. If it's newer and supports prescotts, there is a good chance it won't support a williamette.

It's an older 478 board and I doubt it will run anything faster than a northwood. y'all are right about the voltage being 1.75. Thanks for the advice, but I just wanted to drop in a cheap cpu and then pass the computer on to my dad who's running on a P3 at 1ghz. I got the cpu cheap so no complaints. Everything is running fine. Not the cutting edge, but that's OK.

OP-here is a list of chipset(s) that will work with your Willamette 478 chip:
-Intel 845
-Intel 848 (maybe)
-SiS 645
-SiS 645DX
-SiS 648
-SiS 648FX
-SiS 655
-SiS 655FX (only Asus P4S-800D-X is the only know board that supports all Willamette; Foxconn only supports P4 1.8Ghz)
-SiS 655TX (extremely rare chip)

I'm currently running 1.5Ghz@2.1Ghz Willamette on Gigabyte GA-8S648FX-L. Works great. Have fun with your chip.

I have a 3.0 Prescott running on this Asus P4P800 Deluxe right now.

In the beginning, I had a 1.7 Willamette Celeron

for some reason, Intel made 865P/PE take Willamette Celis but not Willamette P4s.

i had a 865pe run a williamette P4, 1.8GHz...i had to physically move a jumper on the board to set it to either willamette or northwood/prescott. and this was not in the manual either, i had to contact tech support....pita

I had my p4 willamette run on a 865pe, no probs did not have to do anything, asus p4p800-e deluxe was the board.
Funny the p4c 2.8ghz did not run at all not even POST, but the 3.2ghz version ran no probs :S
