Retail X6800 lapped

How far down do you have to go through the IHS before you reach the copper?

Does anyone have a "how-to" guide for this?

here you go this is a decent guide here

it certainly doesnt take much sanding to get to the copper.

Only a few microns.
problem is not so much hitting the copper, but making it flat, usualy they are convex or concave (point of view) and the high spots can take a while to get down flat.

I lapped my 6800 a little bit and the first thing you notice is the outer edges are visably higher than the core area

my guess is the edges are a bit higher in any lga chip

nice find

add

:D

i figured the edges were higher because think about after pushing down with a heatsink or whatever it seems like it would make it flat 'in the end'.

maybe just guessing
