Are you asking if you should lap the heat spreader?

Yes.

No, no, no, you want to remove it. Its a standard flip-chip underneath.
I
wished Intel would have just left it alone and not glued that damn hunk
of
metal on it.

Here, read this: http://www.overclockers.com/tips1087/

As for removing the heat spreader, between the hazards of the operation
and
the increased chance of damage to the core later (when mounting and
unmounting the heatsink) I think I will pass on that for now. I cannot
easily afford to buy a new CPU if things were to go badly wrong.

wise guy, mine frend temporary killed his Tuallie when removing IHS...

Did he manage to repair it somehow?

Believe it or not, he DID it! :-) (a week later when he calmed down
a bit - he is kind a "specialist in MicroElectr.surgery" & repairs &
modifies cellular phones & has all needed equipment to do the job)

The problem was to connect back accidentaly cuted 4 traces on the
upper PCB support (Cpu base-green) for the core connections close to
it (he was using Olfa supercutter while removing IHS.. ) & he managed
to solder them back again after few unseccessfull tries...

I could not believe my own eyes! ... That tiny tiny traces !
(we had no adequate camera to document this & now he doesn´t wanna
touch the CPU/slotket/HSF combo again, it runs perfectly 1.0A@1,42G
again! btw..)

He also "lapped" that tinyCpu core (not the IHS !) & HS w/copper base
+ AS-II paste & he gained few extra °C temp drop.. so it runs @default
Vcore (mine runs at that max. @1,4G even if better sample than his)

Unbelievable! :-) job done!

Yes

I guess you could call it a pet piv. :-)

and the fact that they won't except the fact that the new 800 FSB
cpu's have knocked them off the top..... DOUG

They are still saying AMD is fastest, and that the PR rating (of the latest
CPUs) is accurate? That is not the conclusion of any other review that I
have read. I'm glad I took overclockers.com off my regular reading list.

How large were the traces we're talking about, relative to Athlon cpu
bridges?

There is one undeniable benefit from AMD - competition. Without AMD, Intel
would be free to charge as much as they like for their CPUs and we would
all
probably be paying double.

AMD components still offer a value.

Epox 8RDA+ = $90
XP2600+ = $96
total = $186

Abit IC7 = $150
P4/2.66b = $190
total = $340

Sandra Provides a fairly consistant PR rating.

My OC'ed P4c at 3260Mhz (250fsb) is PR4332

My prior OC'ed XP at 2400Mhz (200fsb) had a PR rating of about 3500
