[ale] RAM upgrade question

[Courtney Thomas]

Thank you for your help.

I just checked the BIOS and there is no CL manual setting and the BIOS 
reports:   Level 2 Cache - 512 KB

So, am I safe to assume that CL3 will work, in that all RAM [512MB] will 
be replaced with CL3, the maximum possible in this machine. It currently 
only has 128MB and is slowwwwwwwww   :-)

Appreciatively,
Courtney
