I have received an a Gateway MX6440 laptop as a freebie, but I'm interested in upgrading its AMD Turion 64 ML-32 (socket 754) to something faster (and more cache). I know the range of processors that could work based on the family list in Wikipedia. However, this computer has the stock bios, and any updates I haven't applied from Gateway doesn't specify processor support. I'm looking to go to at least a 2.2 (ML-40). Has anybody upgraded the processor in this model or other in the series success or failure and do you happen to have any guides handy for working with the heat sink? Any Googling I have done keeps hitting RAM marketers. Update Computer died before I had a chance to try this out.
