Join the Movement: Snap a picture of your FCPGA P!!!/c2 underbelly!

[MadRat]

We have a mission. Intel has locked their FC-PGA cpu's and we want to decode the process if possible. On the underside of every P!!! and Celeron2 is a pattern of resistors that may lead to the logic behind the lock. This is an abolitionist movement, the weak of heart need not apply.

I'd surely try to lead the project if we can get something going. Obviously it doesn't help unless we had enough high-quality pictures of P!!! and Celeron2 underbellies. It would help us decode the pattern of transistors. I am willing to bet that an obvious pattern would unfold if we had decent closeups of the chips.

This is no easy task and Intel has to know it. The inventory of different P!!!s and Celeron2's is vast and covers many speed grades. If we sorted by multiplier it would be the easiest.

P!!!-533eb (4x)
P!!!-600eb (4.5x)
P!!!-500e (5x)
P!!!-667eb (5x)
P!!!-550e (5.5x)
P!!!-733eb (5.5x)
P!!!-600e (6x)
P!!!-800eb (6x)
P!!!-650e (6.5x)
P!!!-866eb (6.5x)
P!!!-700e (7x)
P!!!-933eb (7x)
P!!!-750e (7.5x)
P!!!-1000eb (7.5x)
C2-533a (8x)
C2-800 (8x)
P!!!-800e (8x)
P!!!-1133eb (8x)
c2-566 (8.5x)
c2-850 (8.5x)
P!!!-850e (8.5x)
P!!!-1200eb (8.5x)
c2-600 (9x)
P!!!-900e (9x)
P!!!-1266eb (9x)
c2-633 (9.5x)
c2-667 (10x)
c2-700 (10.5x)
c2-733 (11x)
c2-766 (11.5x)

30 different possible processors to collect underbelly pictures from. Who's up to the task!?! Feel free to send the pics to mm94438@alltel.net. Thank you.

are you only after fc-ppga chips or are slot 1 cpus to be included?

 

[MadRat]

FC-PGA only.

Changed the topic to reflect that.

 

[Czar]

only have an athlon,

^bump for greater good

 

[MrGrim]

C'mon ppl!

 

[ajskydiver]

I have a P3800 that I could get a pic of...I'd have to borrow the dig. camera from work (which isn't a problem)-so I'll need about a week but can be done soon.

 

[divinemartyr]

<< P!!!-1200eb (8.5x) >>





<< P!!!-1266eb (9x) >>



When did these become available?

nicely spotted divinemartyr!

They used to be on Intel's roadmap. Perhaps they'll never come out.

Aj_UF-

I'd appreciate it. A week is not much time to wait.

 

[KpocAlypse]

Bumped until i upgrade to two cpu's later in the month, Then MAdRat, i give ya two p!!! 700e's..

[hans007]

this is gonna be tough, i've seen chips of the same speed grade with a different bottom depending on the stepping, so you will also want to know what stepping they are

 

[MadRat]

Can you show an example?

 

[hans007]

well i dont have one anymore, but i know that the resistors are different sizes, and sometimes some are missing. especially on the cc0s.

 

[OS]

I think you also need to take into account the revisions/steppings (IE cb0, cc0 etc.), since the physical layout of the chip was changed I believe. Not an easy thing you are trying, but more importantly is that you are trying. Best of luck!!

 

[MadRat]

I'd hope with each stepping we'd still see a pattern develop. After all, they do seem to keep the same packaging with each new stepping.

 

[Morpheux]

I have [ics of a P3 600E and a P3 1000EB I can send in next week some time. Send me an email.

 

[hans007]

oh crap , i forgot i've got an extra 1000EB here also, i'll snap a pic and send it to you. PM me please

 

[johneetrash]

since it's extra you can send me the chip ill pay for shipping if you want

 

[MadRat]

My email is mm94438@alltel.net. Feel free to send the pics my way.

 

[MadRat]

Hans007 started it off by sending a P3-1000eb pic.

 

[MadRat]

*bump*

This is a work in progress. Don't forget to send more pics!

 

[MadRat]

Another bump.

 

[Modus]

I thought Intel used a lazer-etching technique to burn the multiplier right into the die after it passed QA.

[MadRat]

Perhaps, but the bottom of the cpu has laser etchings, too. So perhaps its not hidden, maybe its just not been so obvious because nobody looked.
