I have a Duron (Morgan Core) 1.0 ( 100 X 10 )GHz processor, MSI K7N420 Pro ( nForce 420-D) mobo, 1 X 128 MB Kingston PC2100 DDR RAM (CAS 2.5). I want to overclock it to 1.33 GHz ( 133 x 10 ). I use a ordinary air cooler for cpu that came from Cooler Master. I don't know the actual model number, but it's listed in amd recommened coolers list for Duron. Do I need special cooler for this overclocking purpose or my current cooler will do?
