Too much RAM, any ideas? :-)

Have to disagree. Most of us have fixed (or semi-fixed) budget for a DAW computer. Would you spend your extra money to
a. extra nonused RAM
or
b. SSD system disk
or
c. faster processor
or
d. better quality silent PSU
or … ?

Hint: in case of b,c & d, if you want to upgrade, you have to replace existing hardware (expensive) … in case of a, you can just add more hardware (cheap).
