Memory Ram For Macbook Pro
You indeed have the first generation Mac Pro. It can use up to 8 - 240-pin PC2-5300 (667MHz) DDR2 ECC fully-buffered DIMM (FB-DIMM) in (matched pairs.) The modules should have an Apple certified or similar heat sink. Do not use DIMMs without heat sinks as they will not last and may be subject to frequent errors. The DIMMs must be fully buffered (FB) and must be error correcting (ECC) and installed in matching pairs.
Whatever your local dealer sold you if there's no heat sink, they aren't FB and ECC modules, then don't use them.

Ram should be installed minimally in matched pairs and optimally in matched quads. This means the memory modules are the same size and specifications. They should also be equipped with the Apple-certified style of heat sink.
