id be careful
45nm cpus dont always work on boards designed for 65nm
especially on OEM mobos
I know on my Dell I can only use E6xxx Conroes
not the Wolfdales

E6700 on 1066mhz FSB
E6850 on 1333 FSB

You need know if your motherboard supports 1333mhz

Safe choice is E6700
also a little easier to find

There are also Pentium Dual Cores but I am not familiar with them.

I just reread original post
On a 800mhz bus that you have the E4700 is fastest (2.66)
though the mother board might support 1066mhz but
you would have to google your model or motherboard specs.

Now I have the same cpu as you and this is what I did.
E4300 1.8ghz 800mhz FSB -> E4300 2.4ghz 1066mhz FSB
using this modification :
http://www.overclock.net/intel-cpus/341123-intel-bsel-v...

Now you need to know if your mobo supports 1066mhz
you need a circuit writing pen (got mine at Radioshack)
you need a steady hand
you need to be kind of desperate and willing to risk your cpu
but I have read many people doing this mod successfully
and mine has been running about 3 months 24/7 with no problems

I did it because I have a Dell and it is the only way to overclock.

Proceed at your own risk
