what grits do you recommend to get a decent lapping on a heatsink?
3 grits should be enough right?

your suggestions are appreciated in advance! :bigggrin:

    I used 1000, 1500 and 2000 to lap my PAL8045.

    I was only able to find 2000 at Wal Mart. Even AutoZone didn't have it.

    It depends on the heatsink. For extruded heatsinks, I actually start at 120. If they're really bad extruded heatsinks, like cheap slot 1 heatsinks, I'll start with 60.

    If you have a decent heatsink like an SLK or something though, start with 240 or 400; I'd go with 240, because in the long run, it's less work.

    Anyhow, here are the steps I use:
    60/120 if necessary ---> 240 ---> 400 ---> 600 or 1000 (you can stop here if you want to) ---> 1500 ---> 2000 ---> 25 micron ---> 10 micron ---> 5 micron ---> 1 micron

    Mind you that anything beyond 1000 is just for show; it makes effectively no difference at all.

    Man, I saw this thread title and I was all excited. I thought it was about lapping grits... As in eating milled STONEGROUND (not milled in some factory) grits, fresh made in the morning with hot butter melted on them and just a pinch of salt...

    mmmmmmm

    Yeah, Leishi, you'll have to put the foam pads back on. Unless, that is, you WANT to crack your CPU core... ;)

    You might try getting one of those shims that were so popular a few years back. I had one on my 1.4 T-Bird, and I (stupidly) used it along with an SLK-800. Even the original SLK-800 came with foam pads that are designed to do basically the same thing as the shim. So, by using both, I raised the heatsink up off the CPU. Cooked the CPU. Ergo, a shim would probably work too.

    As someone from the "natural state" I resent the implication that WaHo (not to get into the fact that its in Rutt-ville) grits are anything resembling true, good, southern grits.

    No, no Grits are good IMHO but they are abundant.

    Thank you no, I prefer to eat them (food kind) or use them (fine grit wet-dry paper), not kiss them.... :D Kissing the latter could be abrasive on lips, kissing the former gives you a butterfilled moustache if you like as much as I do on mine. Besides, I would not presume to try an manipulate YOUR stuff.... :D;D
