I lapped the CORE

Warhawk · Feb 2, 2003

I had an old processor so i decided to try it. And what do ya know, it went down 5C and no bad effects yet!

JaY_III · Feb 2, 2003

may i ask what CPU you are talking about?

Warhawk · Feb 2, 2003

It was an old p4 1.6 ghz. Ive had it for a while. Its got a 400 mhz fsb.

JaY_III · Feb 2, 2003

yeah, all P4's slower than 2.4GHz are on a 100x4 FSB....
so you poped the IHS off and lapped the core? How much did you take off the core? What grit sandpaper? and what colour is it now? White?

And can i ask what Heatsink you are using? and what kind of temps did you have before you "lapped" the core

Warhawk · Feb 2, 2003

yeah i popped it off. I took a bit off. Not too much. used a very very fine grit. Its a shade of grey. I had 40c before and 35-36c after.

JaY_III · Feb 2, 2003

So if i have this right,
you popped off the IHS.
Were getting temps of 40C with NO IHS

Then lapped the core and now are gettin a 35-36C Temp

What heatsink???? and how fine is fine for the sandpaper?
Not to many peeople are brave enough to lap a core, so all details are great. Any pics?

Not pics YET! Will have some though. I have the regular intel fan.

now that;s not true, there is a 2.26 GHZ on the 533 mhz bus

uumm.. it's hard to believe that the P4 core needs lapping.. I just removed my IHS, and I can say it without QUESTION does NOT need lapping.. And I really don't believe you saw a 5C difference on after lapping a core that was already perfecty smooth, shiny, and flat.. something doesn't sound right...

Warhawk · Feb 2, 2003

Ill get some picks when i can.

Why would you lap the core? I took the IHS off my broken chip and the core is already as smooth as it can get. The core is as smooth as a mirror, in fact thats what it looks like.
