H'OK, so i'm talking about o/cing my 2nd computer, not the one posted in the pc specs. It has a SiS 650 Chipset and...the board itself is a P4SGL-MX and i've been ATTEMPTING to use clockgen to overclock...everytime i try, she hard locks...agh, any help with clockgen and choosing which PLL for the 650? Or even better, a BETTER fsb changer for the SiS 650 chipset... ANY HELP WOULD BE GREAT, post your comments, info and ideas here please. k, later. PEACE! EDIT: i HAVE looked at the PLL chart on the clockgen site and no, that certain PLL IS NOT on my list, halp?
