I assume the following in this reply: you are using DIMMs, one (or
two) cards for 2GB and one (or two) cards for the other 4GB.
1) You probably did this, but until the above reply, it was not clear
that this was your memory configuration: make absolutely sure that the
memory timings on all your DIMMs are the same. If any one is off by
even one in any of the settings, they will not work together. Period.
2) Your answer above was not clear: did the 4GB work by itself without
the other 2GB? If so, the above is your problem. If not, you're in
deeper guano that you think, BUT:
3) Some motherboards (many) will not accept different size DIMMs at
the same time. If yours works with the 2GB alone and the 4GB alone
but not both together, that's probably the problem and you can't do it
at all on your present hardware.
Also, by "running in 64-bit mode" (previous reply), do you mean that
your are running the 32-bit PAE kernel or the x86_64 kernel? Some
hardware doesn't seem to like the former, but that's just what I've
read here before. (I use the x86_64 kernel....)
