Look at the actual chips on the modules. Compare the old ones to the new 
ones. Even if they're identical, thats not enough to say that they 
"match", as modern modules are actually programmed via an onboard 
control chip to provide timing and other information on how the memory 
chips themselves should function. The same physical module can be 
"programmed" several different ways at the factory to provide RAM 
appropriate to several different machines.

Also check you main board specs. Some mainboards require that modules be 
populated in pairs. Put 4 modules in the wrong way and you get errors. 
Put them in the correct way (a matched set per pair of ram slots) and 
they work. Some mainboards are picky about the number of physical chips 
per module. Too many chips draw too much current and the circuitry 
supporting the chips can't handle the draw during memory intensive 
operations.

Your best bet is to get all the RAM at one time from a supplier like 
CRUCIAL for the particular mainboard you have. Crucial guarantees that 
their RAM will work for any mainboard they support. We use them 
exclusively and have done several hundred machines worth of RAM thru 
them with 0 RMA's.
