Lapped core 2 duo IHS pics

[pois0n]

It's relevant to tell what Vcore and program you use to rrad out temps.
Temps skyrocket with increasing Vcore beyond believe.

Also Asus' very nice (NOT!) PC probe says my cpu is just 25C while TAT tells me i'm having a blistering 39C.

This is with 1.425Vcore and watercooling, running 3.6GHz rockstable 24/7.

I lapped mine yesterday but gains seem to be very little, mine was pretty flat compared to others to begin with.

I will let the AS5 settle some more and see how much i gained.

The temp was read with coretemp, e6300 stock speed/voltage. Do you have PECI enabled? I tried enabling it and it dropped the temp that PC Probe displayed by about 15c (making it obviously not correct ) Perhaps that could explain your weirded up temp on pc probe. My IHS was very spoon shaped, took a long time to get the copper showing in the centre of the IHS. The temps TAT reads seem slightly off compared with CoreTemp also, so I'm not sure which to believe, i'd lean toward core temp because TAT isn't actually designed for c2d's, but i dunno, just my opinion

Here's mine after some 50 strokes over 320 grit paper.

It clearly shows mine wasn't real bad, lapping did next to nothing for me.

LOL what the heck are you lapping on your car hood or something

use a razor and check how flat it is because you may not be too steady with the hand there or your surface ain't flat

also use 600 grit as well a little

Need more than 50 strokes IIRC - you need to get it showing all the copper, all I can see is a piece of copper showing on the left of that picture.

Get a big piece of glass and carry on sanding, i'd say 2 minutes sanding one way, rotate 90 degrees, sand 2 minutes etc etc.

You need to get it so its all copper, then move up the grit ranges

my input, someone correct me if im wrong!

Lol, guys come on, this was only how i started, just to show that the copper showed in the center very early in the lapping process, meaning it wasn't as concave as others.

The pic was taken with the cpu lying in the kitchen as this gave me the best light for taking a pic, lapping was done on a mirror off course.

I did not go for a fancy mirror finish, just flatness.

Started with 320 then 400-600-1000.

Here's what i ended up with:

Haha, no pro.
