I've got a Dell XPS M1330 laptop which is already a couple of years old. I've already upgraded to 8GB of RAM and a SDD. Since I do all my development work (under Ubuntu) on this machine, I'd like to get more performance out of it. Currently, the bottleneck seems to be CPU.

The BIOS version (sudo dmidecode -s bios-version) is A15. Hwinfo says the CPU now is a

6.15.13 "Intel(R) Core(TM)2 Duo CPU T5550 @ 1.83GHz"

I know I'll probably have to look for an upgrade on eBay or similar, but I can handle the installation myself.

The question is: Which models of CPU can I use without changing motherboard or other big renovations ? More cores would be my priority. Or how can I find this out myself ?

dots are much faster for me. – Moab Sep 12 '11 at 14:21
Thanks for the info, and especially the sources. I actually looked at the wiki article before but must have missed that part... Two follow-ups, though: 1) Is there a chance of getting more cores ? 2) Do I have to check for things like the Bus speed, or will that "just work" ? – M.G.Palmer Sep 13 '11 at 8:15
I would stick to the recommended processors, they should work without issue. – Moab Sep 13 '11 at 14:05
