Which OCs better to 2.4, 1.6A or 1.8A?

I want a stable overclock using the retail HSF combo.

Well, with a quality chip, it shouldn't be that big of a problem with either, though with the 1.8, you will be running everything at spec since you are doing 133 x 18. AGP and PCI will remain at 66 and 33 respectively, and the memory will stay at 266. Of course, that is if you set your BIOS options properly
