I just picked up a used Thinkpad X60 for the road, and am maxing out the memory on it. According to the docs, it can handle 3GB max, with a total of 2 slots.
In the same breath, the docs mention "always install memory in matched pairs". OK. Nobody sells 1.5 GB RAM chips, so what's a guy to do?
one 1GB and one 2GB?
two 2GB and hope it will know to only use 3GB total?
