asus CUSL @ 1100 MHz +

Can i Overclock a Celery 1000 or 1100 in an asus CUSL ??

sure man those celly chips are still coppermine core

Yes you sure can !!
Go for the celeron 1000....for 2 reasons:

1) The celeron 1ghz and 1,1ghz are the same chip....they only
changed the multiplier from 10 to 11....but the chip's limit for o\c
is the same....they will both get you arround @1,3ghz.

2)The celeron 1ghz is cheaper.

With some luck,good heatsink/fan,and some arctic silver II
you can o\c to 133fsb @1,3ghz.

I hope i helped you.
Just go for it.

if you want 133 then a celly 900 might be a better choice.
