socket 478 Wilamette

[DerwenArtos12]

i recently downloaded wcpuid ver 3(ibelieve). i ran it on my older p4 machine from hp and saw right away that it was a socket 478. i was just like alright. then i saw the fsb at 100mhz and so i checked the L2 cache and it is 256k. so i sat and stared at it for awhile because i am dislexic and thought i may have seen some part of it wrong. so i called my friend matt aka Mith and he looked at it and simply holly heck. we are both dumbfounded. has anyone ever heard of a socket 478 wilamette chip?


will post my wcpuid screen asap.

willamettes come in either socket 423 or 478, while ALL northwoods are 478. socket 478 willamettes exist

 

[DerwenArtos12]

thanx for the info i didn't know that there were 478 wilamettes. are they uncommon or just such crap noone bothers with them?

 

[jjyiz28]

i think its a fairly common chip. im not quite sure if there are any major differences but i believe not since both willamettes in socket 423 and 478 have the same amount of transistors, 42million. northwoods have 55million. the stepping is different so i think your chip has more overclock potential over a 423 willy.

wow i wouldn't have guessed. you are just ful of p4 info.since it runs at 100/400 how high do you think i could get it up to? 133/533 should be pretty easy i would think but not much higher than that or do yo think i could get higher? because it has an 18x multiplier small changes will make a big difference. so if i could get ti p to 133 fsb it would be 2.4ghz. the limit onthe L2 cache will make a good bit of a diference.

 

[jjyiz28]

well i think the most important is if your motherboard has pci/agp locks or pci/agp dividers. if not, then don't expect much. if you do, experiment cuz i have no idea how much u could overclock by.

ps: the info i got is from a book, Upgrading and repairing pc's 14th by scott mueller. very good book , very useful information .

I really doubt you're going to get a Willamette to 2.4Ghz. Maybe 2.1-2.2 if you're lucky, but they don't overclock well compared to Northwoods.

the old willy core for the socket478 P4 are made of the .18 micron flavor....while northwoods are .13...which is why northwoods over clock much better.
the willy cores also have a default vcore of 1.75v whereas the northies are in the 1.5v range.
willies also have only 256k l2 cache and the northies have double that.
thats all i can think of now...

i've got a 478 willy and it's oc'd to 2125mhz w/out problems...

My 1.6 willy and boot into Windows @ 2304MHz, but is not stable. On the other hand it runs peachy at 138fsb

 

[DerwenArtos12]

wow yeahi would imagine that at 146 it would be unsable. but it is stable at 138? that is about what i had hoped. awesp,e thanx ya'll,
and if i can keep mine stable at 138 that would be 2.4ghz. that would be nice.

 

[SinfulWeeper]

Don't get too anxious there. Acording to the CPU database... I have the fastest P4 will in the 1.6 flavor.
It starting out it only ran stable @ 134 FSB tops (very good to the willy standards).
Then I was going to try out a P4m chip and decided I need some practice with no IHS. So I removed it.
The core was cooler and I was able to get 64mhz more out of the chip.

In the end I never joined the P4m crowd...

The highest speed grade of any Willamette CPU is 2GHz. Should tell you something about overclockability. For instance, what are people overclocking to with 2.4-2.6GHz chips using normal air cooling and voltages? Most people are getting around 3GHz. What's the fastest P4 Intel sells? Around 3GHz. Now, the 3.2GHz is on the horizon, plus some people use better cooling or higher voltages, but generally speaking an "easy" overclock would be what the fastest speed grade is.

 

[DerwenArtos12]

well i am not afraid of vcore settings. and i am going to build a watercooling sytem for my case on the way so i think i could do2.4 and thanx to all you who have posted. and i totally agree that about 2.0 is about all i could get if that with the vcore at standard. oh andi recently re-ran wcpuid and sisoft sandra and they both read out that my vcore was 1.5. is that riht i thought willy's used 1.75?

 

[Zap]

You are right, they use 1.75v but many motherboards undervolt. I had a board that undervolted a Willy to around 1.62v. If your board is undervolting to 1.5v, that's pretty severe. Hmmm, Northwoods run around 1.5v +/-, so perhaps your CPU was improperly detected as having 256k cache instead of 512k, and in reality is a Northwood. You can always pull the chip out and look at the markings on it.

 

[SinfulWeeper]

Good point there Zap. I really do not see a willy running @ 1.8 with only 1.5 volts of juice... or at least not stable anyways.

 

[DerwenArtos12]

yeah i know i am completely stumped. i guess i will have to pull i out and check.
