Upgrading Old Socket N / 478

I have a friends desktop he inherited and it has a "blazingly" fast 1.5 GHz Processor at 400FSB. He definitely is NOT a power user and wants to upgrade the processor and RAM (1GB / PC133) if not too outrageous. How fast a processor will fit into the Socket N / 478 400FSB board. Oh, by the way - it's a Dell Optiplex 240.

Any ways to overclock these processors, as Dell is / was so proprietary in their BIOS and such that you had no control over overclocking.

To be honest you will be lucky to find anyone that has an old socket 478 CPU to sell - even used ones are hard to find these days.

Best you could probably find is a 2-3GHz P4. And old RAM is expensive unless you find some on eBay or Craigslist... depending on budget it might be better to start with a newer motherboard or barebones system.

I betcha the fastest CPU that will work in there is a 2.0 GHz P4 Willamette. Since the unit uses PC133, it is one of the first P4 boards and many of them don't take 400 FSB Northwoods, particularly OEM units like your Dell. I'd get a cheap new unit if I were your buddy.

I've placed the important information in bold.

Intel Pentium IV Northwood (400MHz FSB/512KB L2 Cache) Processors are the highest the system will support.

RAM wise the highest is 1GB (which your friend has already).
