Cracked/chipped CPU DIEs

post #1 of 20
Thread Starter 
Hey guys.

Have you ever thought about this?

The CPU's die is really.. the area which has all the transistors ect.

how the hell is it, that when we chip one (like the SKTa chips always do) - the chip doesnt DIE???

(they do when you CRACK them though )


I mean. Think about it. They're all essensial (or perhaps not lol) parts of the CPU.

I reckon, the performance should at least decrease...

maybe some one should do some benching...

Mine died when I chipped a corner off.

depends on how big the chip is and what breaks off with it

S462 (Socket A) CPU's - and most other CPU's + GPU's - has a protective layer to prevent such to happen. I chipped my old 2400+ Sempron and it still worked.

Consider that a chip is made up of MILLIONS of TINY transistors...
If a peice 1mm broke off - that should take a good hundred! (I mean - considering how small the die is - we KNOW they're concentrated..)

What gives?

Does the CPU (obviously I guess) NOT NEED these ?

And the more pertinent question - does performance suffer?

protective layer dude?

Thats all TRansistage! :O - I've scraped ENTIRE chips to NOTHING...

And ALL of the die is constituted, of... that.. stuff you scrape away.. you know.

If you look closely - its like.. some flakes (pretty amazing how small those things are).

remember - the broad part of the chip is just mostly... the circuitry that goes to the pins I reckon.

I chipped a tiny tiny corner off a XP 3200+ chip and it still works perfectly in my HTPC and I wondered the same thing. Who knows.... maybe those guys figured it might happen a lot and put in a little buffer zone..... I'm guessing probably luck though......

I shall sacrifice.

I already lapped my die!

You can get lucky I did with one of my 939 chips. I think there is some room at the edges that dont have anything on them. I think it also depends on how much of a crack propagation you get coming from the chip. While one chip may look small there could be miniscule fractures that extend into the chip that you cant see that totally ruin the cpu hence why some die and others keep on kicking.

the edges are just exccess die because if it wasn't if you made a mark/knocked off a little 1/10 of a millimeter part it would be gone.

ALso the top of the die has a glossy coat
