Which processors can i use to upgrade my socket 478?



Hi ,i have a sony vaio pcv rx2d with socket 478 and a pentium 4 1.7 ghz processor, here’s the link : http://ark.intel.com/Product.aspx?id=27426 .
I was wondering if i could upgrade the processor to get more juice out of it. so my question is that, Which processors would my system support?


It seems, if you’re lucky, it may run a 533FSB Northwood based CPU.

Definitely cannot run 800FSB or Prescott


Ok thanks Matth , i really found the link helpful. so i guess i’ll be buying a 2.8 ghz northwood or a 3.06 ghz northwood like the one in the link.
