Lapped my E6600 today with this kit, good stuff and inexpensive.
Pics:
Getting the Scythe Infinity out of the P180s in and out without removing the board is a real ******.
The HS after removing it.. you can see that there are some gaps in the contact between it and the IHS.
You can see how concave the IHS was. I started at 800 grit since I didn't see any reason to be so rough, but it was taking too long. On to 400...
Various stages of lapping, from start to finish. 400 grit was a lot faster, then went back to 800 and to 1000.
The finer paper that came with the EasyPCKits package wasn't labeled in grit but in microns, like 40 microns and down from there. It didn't get the flawless mirror shine that I saw a lot of people get with 1200-2000 grit paper from the autoshop, but it was still flat nonetheless. The IHS is still highly reflective, just shows some scratches still. Having it absolutely perfect probably affects performance in no measurable way.. it just would have been nice
Trying a new (for me) method of applying AS5. I used to do what a lot of other people do, spread a thin layer evenly with a card or razor blade. I'm told this is a bit better as the line goes straight over the two cores, so I'm giving it a shot. I know it looks like I jizzed a ton on there but I had to smudge it around as it was uneven.
System back in place, that thing is heavy and it sucks to unhook it and move it about.
Screencap of my OC and temps. Before lapping, on load it went up as high as 62C during the day. During most of Orthos it was 50-51C but I think it went down to 48 due to my room cooling throughout the night. The difference is quite excellent and it might get a little cooler once the AS5 settles. Idle temps are 40-42C both before and after lapping.
This is the same OC I had before the lapping, I haven't had time to try and take it any higher. My voltage is set to 1.475 in the CMOS but this board notoriously vdroops by about .10v or so while on load which explains the 1.368v reading. I've been afraid to go higher than 1.475v (CMOS) since I wasn't comfortable with the 62C load temps from before, but I won't get higher than 400 FSB (8x multi) unless I do. With 9x I don't think I got higher than 360 FSB, which makes the 8x a better choice. I'd really like to get 400x9.. here's to hoping.
A few things worth mentioning: I wrapped up my CPU in scotch tape with the plastic back piece on to make sure no pieces of nickel or copper got on the back of the CPU. I used 70% isopropyl rubbing alcohol to clean the CPU before and after lapping. While lapping, I didn't use any liquid of any kind; I read a lot of different opinions on whether or not to do it wet and I just decided not to so I wouldn't have to worry about it and it turned out fine. Maybe doing it dry is why I didn't get a perfect finish?
And the pics are mirrored here in case Imageshack goes down.
