When I say 'Pin layout', I mean I need a slot list of what each pin does. (Even the pins that do nothing).

Thanks!

Page 38 gives layout
Pages 39-51 give pin function

is the link to the hardware develope site for the P4.

The pinout diagram is here:

And the data you want is in chapter 5. Of course, if you want to know what it all means, youll have to ask someone else. Cos I havent a clue.

BTW, what do you want this for? Its not exactly something that has much practical use for most people.

He wants to daisy-chain 2000 P4's together to build a super-computer to take over the whole internet of course :D

Well he doesn't need the pinouts for that. A *cough* simple *cough* Beowulf cluster of Beowulf clusters would do just nicely .....

You are correct. We are working to our goal. World wide dominion of all humans computers. we can then halt ALL operations on the internet, and this will make you all pay us in fruit loops or captian crunch (the one with the berries)!!!! [img]smile.gif[/img]

Well, I need this for a special reason-- I was cleaning out my PC of dust (and there was a LOT this time for some reason) anyway, I am cleaning the PCI boards and such with a light stroke of a special paintbrush (Static free) and the Fan and heatsink were really gummed up with dust and hair, so I go to remove the fan and heatsink, but I was shocked to my bone when the PROCESSOR was STUCK to the epoxy ON the heatsink. I Closed my eyes and said a prayer, knowing how EXTREMELY fragile the pins are. I take a look.....

1 Pin is bent enough to not allow it to go in the socket. (BTW, when I removed the heatsink, the damn lock bar was DOWN?!? I didn't force it or anything.. Done this to HUNDREDS of PC's. This is a first.

Anyway, I have some delicate tools for such work, and I went to slowly and carefully bend the pin back into it's correct location, but BAM, it snaps off from the processor. I almost cried. [img]smile.gif[/img] . I said a few angry words, and I know it's under warranty, so it's not a death sentence BUT.....

I decided to install the processor and see what happens. It boots, and BIOS comes up as usual when a CPU is removed. I choose the correct Freq.. 2.4Ghz (yeah.. it's an expensive little sucker) anyway, I set the settings, and reboot.

It works perfectly. I have even done burn-in tests and benchmarks, and I'm still at the exact same benchmark I was before... (3D Mark 11,952).

Anyway, I even did bus processing tests (to see if I am now writing errors to the hard drive). All CRC's are fine.

I THINK the pin that broke off was either a nulled pin, or it has some error checking or safety function that isn't in effect.

It was D24 I believe...

Anyway, since it wasn't MY fault the dumb lock doesn't work, I am getting it RMA'ed. Just to be safe.

Maybe this is just this Motherboard, or maybe it's a batch of them--had that happen before when I built machines.. Mine is an Asus boards Anyway, it'll be replaced. I don't wish to take the chance. (This PC is my HOME PC, not the server. don't worry! :D )

Could've been for Hyperthreading perhaps. I know the 2.4 had the ability to hyperthread, but they were locked at the factory.

That was a pretty slick escape, mind you, probably a one in a million shot that the broken pin still allowed the proc to function.

Sure was! I seriously didn't expect it to boot. [img]smile.gif[/img] I was expecting error beeps or a lockup.

glad your home PC is okay Z...

good thing it also didnt fry your motherboard.. its happened once to me but i inserted the powercable incorrectly and BAM friend motherboard and fried processor... it was my first time installing a processor then ...

Ziroc!

I did the same thing a few weeks ago. I was replacing a motherboard for a customer under warranty. So I needed to remove the CPU to transfer to the new board and both Processor and Heatsink pulled out with the lever down. I did not want to use a screwdriver to pry it apart so I called Tech Support(IBM)for advice and to complain ;) . The tech said to place the CPU over the socket on the new board and lock it down with the lever down! I was more than shocked and hung up. There was no way I was going to attempt it, so I called again and got another tech. I told him about what the other tech said and he could not believe it. I told him I could not understand what kind of compound would make it stick like that and how can you possibly change a systemboard if this happens. I was glad that the CPU wasn't damaged. I was then transferred to the Head Tech. I was told to pry it apart with a screwdriver. I told him he better teach his techs a few things because if they give people this kind of advice they're causing all kinds of trouble.

In the end, it all worked out ok.

I just can't imagine how a CPU can pull out of the socket with lever down, though.

Mark

Hmm, maybe this epoxy is bad or something? But yeah, it was stuck like glue!! I took a very flat putty knife and slowly popped it apart. But geez, When I pulled it out, and saw that it ALL came out with the lever down, in my head (when I closed my eyes) I envisioned ALL the pins bent. GRRR!

I'm STILL not trusting this CPU, it'll be RMA'ed asap.. I don't want to take a voltage risk with it.

Thinking about it, what holds the CPU in place is simply friction -- the little plates being compressed against the pins. So what it means when the CPU came out is that the strength of the bond between the CPU and the heat sink was greater than the force of friction holding the CPU in the socket.

Enough force, and (as you unfortunately saw) away it goes. Simple physics.

As for the techs with their bad idea support... passing it up the support food chain is the way to get that corrected, and deity bless those who are smart enough to listen to what the "experts" tell them and question it... [img]smile.gif[/img]
