According to the memory upgrade option offered on the RM webpage, RM memory upgrade it specifies DDR PC2700 SODIMM for both 256 and 512MB options. My preference is for 512MB.
However, according to the specifications tab of the Product description page (1st link, above), it says that I need 266MHz for the Celeron M.
Thats the background. Well, I've looked, and I am finding it very difficult to find 512MB of PC2700 266MHz DDR SODIMM memory. My local storeman has had trouble too, and says it is quite old. My questions are;
Does this memory actually exist?
Can I use a substitute, such as PC2100 ?
