Lapping a Core 2 Duo? - Page 2

post #11 of 31
I ordered the same kit as Jacko to lap mine. And order the refill just in case you need more sheets. But you can go to home depot and get the sheets there. Just use a piece of glass so I come out flat.
Use the lowest grid till it's flat. Then use a razor criss cross coner to corner. Get some back light so that when you have the razor on the chip and see no light coming thru and start to use the higher grids of sandpaper.

Pickup a socket 478 $5 chip and practice on that. I did, and it helped immensely.
I guess Ill practice on my P4 3.0Ghz thats lying around, but will I need more clean sandpaper after im done practicing?

@ waqasr, that looks awesome
I'll need to do my heatsink as well, its far from smooth

Can someone explain in what motion I need to do this?
Also, whats the difference between wet and dry, and how do u get it wet?

Up and down is fine..and turning it 90degrees every couple minutes..some do figure 8s..it doesnt matter too much. About the Wet and Dry thing..thats exactly what it is..wet sanding you just add a little water to the paper to cut down friction because the hsf can snag and judder on the finer sand papers and dry sanding is just normal sanding..Also if you cant get a sheet of glass just use a mirror, its equally as flat.

Thats a good tip, I dont have a razor exactly, are there any common items that would also work.

And if I do get a razor, I have to be careful not to scratch the cpu right?

All you going to do is place the razor on the cpu seen razors are flat and straight at the edge.

feeler gauges have a straight edge as well and could be used like a razor blade would be.

Go to an auto parts supplier. Body shops routinely use high grits of wet/dry sandpaper, so most well-stocked auto supply houses have grit from 400-1800 or higher. I got mine at Pepboys ( big chain in the US).

I put an X in permanent marker on the cpu and sanded til it came off,then I repeated the process with the same grit using 200 to 2000. I also found with practicing on a old cpu that using the 8 motion left deeper scratches, so I stuck with the up & down motion,and rotated 90* every few strokes.
