best overclocking C2D config !!!

[morg]

i plan on buying the best cpu spec available
on air cooling with the lowest budget possible

if anybody sees something wrong in it, i would like to know

limit spec is 3.7ghz C2D architecture with 4mb total cache
( not looking at quads as they must be watercooled )

smallest CPU with 4mb cache is the 6320 7x266 = 1.86
to reach 3731mhz, it needs a fsb of 533mhz
so i need PC2-8500 1066mhz ram.

i need a board with a 533 mhz reliable support.
Asus P5K seems to be a good reliable one.

there i go with the hard questions. i have a 120MM Zalman 7700-CU
is it compatible with the P5K board... ???

optimisation question... at the same CPU frequency, will i get better performance using a higher fsb ?
example :
using 622*6= 3730mhz 1250mhz ram
instead of 533*7 = 3730mhz 1066mhz ram

what difference would it be to use 800mhz ( fsb400 )
and a 533mhz fsb on CPU (533x7)

compared to 1:1 spec with 1066mhz ddr2

Ah.... yeah. You might be better off getting a E6420 so you will have the 8x multiplier if you need it. 8 x 475 = 3800.

Oops... double post.

thats rather ambitious (although not impossible) goal of 3.7Ghz air.

I have what is arguably a very high performance water cooling system and it will run 3Dmark06 (15,204) at 3.73Ghz, but would I trust it day in day out....NO. Here is a a comparison I did comparing a E6400 to upcoming Penryn with 1333FSB and higher. C2D performance scaling

There are a lot of variables and interactions of different components that simple specs don't show until you do the build. FSB's above 500 again while not impossible are tricky to get stable.

Good luck,
