How much can the motherboard/model support for ram in total?
What is the largest single stick of ram that each module can support?

How large are the sticks that you have purchased?

How many slots are there, 4 I am assuming?

Is the ram seated in the modules properly? If you take out one of the new sticks will it boot? If you take all the new ram out does it then boot? Crucial.com has an analyzer that can answer most of those questions about what the board and module size supported are.

Is the make/model of your motherboard a secret? If not, please post it.

The best RAM for an Athlon64 X2 is DDR2-800 (PC2-6400). Anything other than that will result in a performance hit.

The memory may also be different enough that they cannot run together, at keast without experimenting a bit with manually setting up the memory. Different voltages, timings, and latency can have at least as much effect on how the memory will run in your machine as the size and speed. Usually with memory of different speeds you need to make sure that the slower set is in the 'first' pair of slots and of course you need to double check your manual as to which slots are each channel so pairs can be kept on the same channel (they are not always the first two slots next to each other, sometimes they are the first and the third, and the second and the fourth).

As asked, provide the motherboard make and model plus all of the memory specs and/or make and full model number for better advice.

You have to be a little bit crazy to keep you from going insane.
