okay so i'm at it again.. haha pretty much the same idea as last time. i want to upgrade my laptop to the highest possible cpu and along with that upgrade max quantity of memory as well as max speed. this is a dell inspiron 1501 with the amd sempron 3500+ processor and currently 2x512mb of pc2 4300 ddr2 memory. dell's website doesn't really provide much information about the laptop or even its upgrade potential. i've searched around for answers and have found some, but only to see that others had slightly different cpu's to begin with and that made me wonder if we even have the same type motherboards. some people had semprons like me at different speeds and others had turions, etc in the same exact model inspiron 1501 inquiring about exactly what i'm wanting to do which is upgrade the cpu to its max. from what i gather and according to ebay, the part number for my motherboard is the UW953. haven't found much more than that. as far as the cpu i prefer... obviously not a sempron so moving up... turion or greater. thing is, there are so many different turion processors that will make your head spin. http://en.wikipedia.org/wiki/AMD_Turion i don't know too much about these processors so maybe someone can shed some light perhaps cube? heh it would be nice to get the x2 line which is dual core. it has the same S1 socket as the sempron uses although i don't know its full compatibility. looking at the wiki site above i would like to stay away from the 90nm chips as they get way too hot. the 65nm is a lot better such as the tyler. i don't know that the lion or anything below that will work though. i'm not even sure the tyler will work. i need someone to help me out with this. as the cpu gets selected, so then will i want to upgrade the memory to its max and unsure but maybe the speed of the memory can go from pc2 4300 to pc2 5300. i did some searching and found for example, the laptops that came with tl-60 tend to have pc2 5300. anyways any input will help out and i appreciate it. below are images of cpu-z of the laptop as of right now just to let you know what it has in detail.
