pentium 2.4ghz mobile questions

[viper650]

i have one of these laying around. from the pin arrangement, its exactly like the s478. this is not a pentium M, or celeron M. its from 2001 and it is just a pentium 4 mobile. came out of a dell laptop. can i stick this in a normal 478 board?

[cirthix]

yes, but the multi will be locked at 12

yes, but the multi will be locked at 12

ok, so if its a 400fsb chip now, it will function at...? i dont know the multiplier on it.

Mine booted straight up at 200x12 @ default VCore (1.50)..in a "super-cheap" Abit VT7 (Via PT880) mainboard.

your 400fsb chip booted at 200x12? that makes no sense... thats a 100 fsb increase? is yours a northwood core, 512 cache, 400fsb chip?

Had a selection of these back in the day, used to pick up 1.8's off of ebay for £30 and then run them at 3.3GHz+ on air, superb chips. Shame they didn't have HT really.
Bear in mind the multiplier is locked at 12x regardless of the rated speed as the BIOS cannot deal with the Speedstep.

unless you find a bios which supports speedstep.

Know of any? :)

[ibby]

not personally, however their was a thread about on xs which had info about the multiplyer.

Could be worth looking at "big toes" bios,

Why does it make no sense? :)
Yes..it's a NW, 512 cache..400fsb chip..
I must correct myself.. it is not a 2.4Ghz..but a 1.8Ghz.. (18x100 "default").
In a "desktop" MB it will default to MP=12..
As I've put it in a Via chipset based MB it is no point trying to raise the FSB (hint: PCI/AGP lock).
It may run at 3Ghz (or more) as Thorburn points out.. but it's still no contest against any of my Dothans.. :)

i dont know what it boots at because its such an old chip. but it says on the IHS that its a 400/512 northwood

Silly me... :confused:
I think I misunderstood...
Of course it will not boot *default* at 200x12.. It will boot at 100x12, but as these chips are highly willing "clockers" they will "take" FSB200 at ease.. hence my first post about setting FSB=200 in bios and boot..
