I have a Dimension 4550 and an Inspiron 9300. The Dimension has a Pentium 4 2.4Ghz Northwood and I want to clock it to around 3.0Ghz. Its motherboard can only hold 1 GB of memory. The Inspiron, unfortunately, has a Pentium M 730, so I can't do the pin mod. I know this a long shot, but does anyone know where I can find modified BIOS that will let me overclock these systems and add more memory to my Dimension. It like to squeeze, hopefully, at least another year out of my Dimension.
