Someone on eBay has a mini for sale that he upgraded from a 1.5 core solo to a 2.16 core duo. Can that be done without causing other problems? I dunno - like excess heat or something?
Core solo and Core Duo machines only take up to 2gig of ram.
Core 2 Duo machines take 3 and change.
This is a function of the boards, not of the chips. So, even if you take a Solo and put in a Core 2 Duo chip, it will only take 2 gigs of ram, tops.
I'd be very careful buying this from ebay.
What chips on the motherboard changed?
