RAM does operate at different speeds and this can be an issue if the speed the RAM operates at, is incompatible with the BUS speeds of the motherboard for example.
In addition it does not hurt to take the domestic vacuum cleaner to the RAM slots to make sure they are dust free and rub the contacts on the RAM chips with a piece of Blu Tack (removes grease) before reseating them.

Not necessarily � the fact that the system sees the memory doesn�t guarantee

boot-up memory checks are fairly cursory.
When an application launches and requests a certain amount of memory the
memory will be allocated to it, but in most cases it won�t all be actually
used (accessed) until the application actually needs the memory. This would
be particularly the case with something like Photoshop when it is set to
have a large memory partition. So just because an application launches which
allocates a large amount of memory doesn�t mean that the memory which is
allocated is all OK.
I would suggest that you try something like Newer Gauge Pro
(http://www.versiontracker.com/dyn/moreinfo/macos/15583) to test the memory.
There are also other applications available which test memory, but Gauge Pro
is very straightforward and does a far more extensive test than the boot-up
test. If my memory serves me right you have to boot with virtual memory
switched off to use it.

I've reinstalled the both memory modules and it shows up in Apple profiler.
If I allocate memory to an application that 'absorbs' the total memory
available. The application launches ok. If I try to launch aplication it
invites me to quit the first. Can I take it from this that the memory is
usable?
