Lapping a Core 2 Duo?

post #1 of 31
Thread Starter 
I might as well try and lower my temps.
Any useful guides, precautions, advice?

Tools I already have
  • 99% alcohol
  • Air Duster
  • Glass Table
  • Q tips

What I need (pls be specific)
  • Sandpaper.. what kind? How much of it? Homedepot? (keep in mind that I'm broke)
  • ?
  • ?

And if you want to share your success story with lapping, you are more than welcome to encourage me

Thanks in advance!

you want a small peice of glass and wet/dry sandpaper for 220-1500 this is what i use any away. 220 gets the chip rather flat. then 400 then 800 then 1200 then 1500 if i have it

I used sandpaper grits 400, 600, 800, 100, 1200, 1500, 2000, 2500 on a piece of glass. I also ran the paper under some water before I used it, and once again halfway through using that same piece of paper. I wiped it with a lint free cloth and put it back in my system. People act like you need to soap the sandpaper and clean everything with alcohol...I didn't do that and my load temps dropped almost 4C.

This is what I ordered: http://www.easypckits.com/products/hslkwg/

Need more info, in what order did you use the sandpaper? In what motion did you move the cpu?

P.S. it's not really that expensive, but shipping to canada is the price of the kit itself, would this cost even more if i just dropped by a home depot or something?

yup..Use a low grit like 200 to get through to all the copper and get the IHS flat..from there i just jump to 800 for a while until all big scratches are gone and its got a little shine to it, then 1500 and this gets rid of the marks created by the 800grit and 2000 to finish it off and give it a mirror finish...but remember mirror finish is not the aim, its the flatness..and if you do want a mirror finish aswell its normally obtained with 1200 grit and above but with these do not wetsand, just drysand it..Heres my Q66 lapped.

That's not too much for what you are getting. I have seen more ex$pensive kits on EBay with less. Buying the paper individually can be hassle and end up costing you more because a lot of places only sell the paper in packages and sometimes it is difficult to fine the finer grit stuff. I lapped my quad and it brought the temps down an average 4c per core. just make sure that you use alcohol as the "wetting agent" water could cause problems if the processor is not totally dry....... Just make sure that the shipping is reasonable........ Good Luck!

You start at 400 and work your way up to the highest you got. Keep at the 400 and 600 until all you see is copper on the IHS, once all copper is showing, move up more on the grits to flatten and make it shine

Number one rule:

DON'T PRACTICE ON YOUR Core 2!

Pickup a socket 478 $5 chip and practice on that. I did, and it helped immensely.
