at 1.8 ghz stock, with a locked max multiplier of nine, you can set
the ram setting from ddr 400 to ddr 333, change the voltage to 1.45
for the cpu, set the fsb at 245, youll bring that baby up to 2.2
stable.
this will set your ddr 400 back to its origional bus speed withought
overclocking the ram at all.
as far as overclocking beyond that point, i have heard that the origional hsf
will provide enough cooling for up to 2.5 ghz, thats quite an
overclock right there 700mhz WOW, thats withought extra cooling, ive
heard of these f**kers flying at 3 ghz no problem with the proper
techniques and cooling
