When I mess around with the memory timings such as 2/2/2/5 and set the
voltage to 2.7 it would not post and I had to do a hard reset by removing
the battery and moving a jumper. Is this normal?

Yes, Unfortunately 2.5 Cas latency is the highest you can go as Crucial RAM
is nominally rated at 3. Running at 2.5 is overclocking on its own. Your
original timings of 2.5/3/3/7 are good if they work well and I'd leave it at
that. You could increase the voltage if you get random lockups to see if
that stops them...
