I wouldn't do it.

I know some people lap thier processors but how do I got about lapping it? What grains do you use? Heatsink isn't a problem but I dunno about the processor. I'm just paranoid also about scraping the black part around the metal.
i can agree to that my friendOriginally posted by kleptophobiac
People who did it on the palomino and down processors were still nuts. That metal cap isn't remarkably thick, nor is it easy to precisely lap the whole surface of something that small.
Risk/reward ratio is totally out of whack..

Do you really think that the shiny thing you're looking at in the center of the chip package is really the core? Nope.
The core is sandwiched between a layer that bonds to the conductive pads on the bottom of the silicon substrate (the plastic PCB) and a metal cap to protect the core. Yes, the metal cap is a ton smaller than Intel's IHS, but the P4 has a metal cap over the chip itself in addition to the IHS as well.
If there were no metal cap, the tiniest piece of dust (or thermal paste) would destroy the processor the moment it leaves the clean room.
Just curious you on air or water cooling?Originally posted by kleptophobiac
Silicon is metal, sortof.
There are transisters etched into the silicon, with copper interconnects. The whole package is then sealed off with some adhesive and a metal plate. When you chip the "core", dust enters the silicon chip and kills it. Also, if you apply enough force to break the metal on top, who's to say it wasn't enough to break the silicon chip underneath?

Here, you disbelieving SOB. Here are naked chips that end up being used in inkjet printers. These end up being coated, at which point they can survive the non-cleanroom environment.
Sorry for the blurry picture, but you try taking pictures with a low-end digicam from three yeras ago in the dark of a shiny surface.

I've heard of a few ppl using goo gone (or something of the sorts) to get rid of that weird sticker-like thing on barton cores, then cleaning it with isopropyl alcohol. Temperature difference is slight, though, more noticeable if your heatsink is also lapped (still not very, though). Other than that, it'd be risky to lap an AMD core, though if you had the money, you could try and tell us how it goes.
