Slightly annoyingly, I had the damn thing open over Xmas to install a bigger
disk - if I'd thought about it, I could have at least looked to see what the
memory situation was, if not actually done an upgrade.

Perhaps I should go back to Sun hardware. We have machines at work with 1TB
of main memory in them.

As was mentioned earlier, just run the Crucial memory scanner in this
link and Crucial will advise you on exactly what your memory total is
and inform you of what it is capable of, plus what type of memory you
need and if it will be possible to increase it.
A very useful little program

Except it only runs under Windows. Which I don't.


Something else I've learnt today, thanks :-)
