|Successfully upgraded my 1.66GHz Core Duo to a 2.0GHz Core Duo (T2500). The operation is a bit tricky the first time but if you're careful you should be OK. Why not a Core 2 Duo? because I only needed the extra Ghz to play Hidefinition H264/VC-1 and 1.66 wasn't quite enough, also the Core Duos are much cheaper than the Core 2 Duos.
The plastic bolts on the heatsink are a bit of a problem but I used some small pliers to pinch the ends in which released them without any damage. I had to do this a number of times, for various reasons. , without damage. I removed the stuck on thermal pads with some Maplin's Electronic Solvent cleaner and then some iso alcohol (tape head cleaner). Then put some silver thermal paste on and spread it out on the chip with a credit card, only a small amount, to get it smooth.
The first time putting the heatsink back on I put it the wrong way round, easily done, and the heatsink cowl wouldn't go back on! Turned it back 90 degrees and it was OK.
After running temperature checks the heat was getting to high on load, i.e. near 99º C! Think the CPU's auto cutout kicks in at 100º C so realised this wasn't right. So back off with the case and dismantled again. This time the operation was much quicker, i.e. 10 minutes. Now I put some more paste on the chip but not too much. Back together and the temperature peaks at around 90º C which looks good.
So watch that thermal paste, not too much but not too little...yes, a bit of trial and error. Also you need to watch out when putting the heatsink back on as it can slide about and move the thermal paste. Putting the heatsink back on is the trickiest part with those pesky nylon bolts!
Working great now and no skipped frames with my HiDef material.
