is this memory new or used?

Hello Brent, The modules are new but not in retail packing. Thanks a lot,

my system currently has Samsung M391B5273CH0-CH9 1028, 4GB @Rx8 PC3 - 10600E-09-10-E1 The difference is CH0 vs your DH0. Would your memory be compatible?

Hello Brent, Yes the CH0 and DH0 are compatible and will work for you. Thank you,
