memory problem

i jave recently purchased two 128mb pc100 non buffered non eec memory modules .. when i in stall them they dont read as they should
when i install one it reads 128 ( normal )
when i remove that one and in stall the second it only reads 64 mb ( mislabled maybe? )when i install the other one that was reading 128 with the existing one it only reads total 128 ( should be 256mb )now i have an existing 64 that i added too and its no only reading 192 and it should be reading 320 total ... if anyone has any ideas let me know
