Aren't some 423 willamette rare? i think the first 1.4ghz release is pretty hard to find.

FWIW, I have 1.3, 1.4 and up to 1.7 s423 Willamettes in my collection. The faster, especially 2.0 have been too few and thus expensive for what I'm willing to pay ...

I have yet to see a 2Ghz 423 Willy, been searching for about 9 months now, I have the 1.3, 1.4, 1.7, 1.8 and 1.9 in my collection the 1.3 and 1.9 are the only two I actually bought separate.

I do have a rather cool Socket 478 to 423 interposer that lets me use a 2.6Ghz Northwood on a 423 board, it works really well even with the reduced bus speed of the 423 motherboard. I'm considering throwing some high res images of the interposer up here on Vogons for anyone who might be interested in reverse engineering it.

Its highly amusing to me to watch a Tualatin 1.4s run rings around the 1.3 and 1.4 Willy CPUs, the first Pentium 4 CPUs were utter dogs for performance and with the first gen of RDRAM being as slow as it was it must have made early adopters regret their purchases. (even the 1.5 and 1.6 P4s don't offer much competition to a solid OCed Tualatin 1.4 system, set that Tually to 1.6Ghz and watch it trash the P4s)

Wow, I only thought you'd be able to run an s478 Willy in those interposers, or at least that s423 boards didn't have voltage and microcode supporting NW

I have that adapter running on a QDI PlatiniX 4X-A, I cant remember if its got a modded BIOS but its possible that it does to support the Northwoods as it'll take any of the 400 FSB models except the 2.8 and 3Ghz models which require a bigger VRM and cooling. (Its a beautiful board being QDI)

IIRC there were a few motherboards that came with these adapters as extras, I think ASUS had a board that could handle it.

Iirc the ASUS adapter would work only with Willamette. But for all I know, the board is the deciding factor in this.
I do have the ASUS adapter, but I don't think it could help me use a Northwood on any of my s423 boards (of which I have very few).

I have a s478 ---> s423 adapter that works with Northwood CPUs. My adapter is an "Upgradeware".

I'm not confident that the motherboard actually needs a BIOS that supports Northwood but that depends on how the motherboard and BIOS handles unsupported CPUs. 😁 The Asus P4T-E seems like a safe bet, I'm sure that's what I used when testing the adapter. Tomshardware also managed to get their P4T-E going with an Upgradeware adapter and a Northwood so the odds should be good.

If I remember correctly I started experiencing timing issues (instability) when getting close to 3 GHz.

Yeah the guy I bought the adapter and board from said the 2.8Ghz and 3Ghz should in theory work but the 423 boards he tested couldn't supply a stable voltage to them, I figure the VRM is the deciding factor when pushing 3Ghz so 423 boards with big VRMs may be able to run a 2.8/3Ghz Northwood via the adapter.

The QDI handles the Northwood just fine at 2.6 and even detects it correctly.

Im curious if its the board that is the determining factor here for support, I have a few 423 boards, one is an Intel one which Im interested to see if the adapter will function on.

*side note the 3Ghz Northwood is an OEM CPU so if you have one, lucky you ! (Rather rare model to own)

I have this Northwood SL6PG P4 3066 HT. It's somewhat hard to make out the text on the CPU as it has seen many sockets in its life. The mobile Northwood P4 3066 SL726 sitting next to the SL6PG is useful for finding a motherboards max FSB as this CPU is stuck at the 12x multiplier on desktop boards but will do high frequency.

I just remembered that I should add a picture of my Gold Top Pentium 66 here since we were talking about them earlier.

And yes this SX837 can not really handle numbers that well... 😁

And no I have never opened the ESD-protection.

Just now a succesful POST with a GX1 300 Mhz (PGA). As stated by feipoa these are quite uncommon in PGA format. I wonder if the 333 Mhz version exists at all in PGA.

you ppl forget or dont take in account where i live. In a 3rd world country its harder to find high end stuff because not many ppl buy it in the 1st place.

Been looking for a 300 like forever.

Say you're gonna bench it.

I do. Not mentioning the many economic crisis.

Yes, but companies tended to send out their failed chips and cards to 3rd world countries, so you have a shot at finding some oddball CPU's and sound cards.

Not just the failed stuff, but sometimes after new products are released, formerly high-end stuff becomes unwanted in the domestic market and then dumped some place else.

I found plenty of high end parts in former soviet block countries.

I will eventually, need to finish the build first. I'm curious how it compares with my GX1 233 Mhz Advantech build.

One of the rarest x86 processors. It's almost impossible to find.

So that's what was in the brief case at the end of Pulp Fiction! I always wondered ...

What does the bottom look like? Who makes it? For what?
