Not exactly an overclock yet, but maybe??

I am considering buying a used E5472 processor to use in this P5K
Premium board with a 771 to 775 adapter sticker. My memory is a pair
of 2GB PC2-6400 samsung M3 78T5663EH3-cf7. This processor has a 1600
MHz FSB. The motherboard seems to be
speced for 1600 FSB.

Does anyone have any knowledge or opinions about this kind of
project? Is it likely to work? Will it overclock?

I finally got around to trying this processor on the P5K Premium
after my problems on the Abit IP35 Pro.

I modded the ASUS AMI bios using the following:

Booted it up to bios, reset to default, rebooted to windows. Windows
runs for awhile, then crashes. That's way further than I got with
the Abit board.
Speedfan seems to display temps about 15C below the real temp
displayed by coretemp on the E5472. It was right on with my Q8200.

Temps, still using the stock Intel heatsink, seem to be higher than
they should be, so maybe that is why it crashes. The E5472 seems to
have a max temp spec of 75C. Speedfan was showing temps in the mid
60's, so with the 15C offset, maybe too high. The E5472 is supposedly
80W max compared to the Q8200 at 95, so I'm a bit surprised. They
seem to both idle around 50C, compensating for the speedfan errors on
the E5472, with speedfan controlling the CPU fan speed according to
temp.
I thought these newer processors were suppost to slow down if they
get too hot, rather than just crashing. Could it be a memory error?
The DDR2-800 memory should be able to handle this speed, right? ASUS
claims this board is good to FSB 1600, which I understand matches the
DDR2-800 memory
I've got the Q8200 back in now, as this is my HTPC machine, so I
don't want it crashing, but will do more playing with the E5472 when
I have the opportunity.
I'd appreciate opinions and suggestions.

I did more research about the Tjmax value for the E5472, and it seems that 85C
is the consensis. RealTemp uses that value, and CoreTemp uses 100, which I can
to figure out how to change. So, Speedfan was initially displaying the correct
core temps, and my temps were OK (on the second test described in another post.
My idle temp currently is around 32C, and my temps in the hot Prime95 torture
test are in the low 50's, at 3.3GHz overclock. This is a nice processor if you
have a motherboard that will handle 1600 FSB.
