You get these 4 old used RAM memory sticks, each with genuine gold components that could be recycled.The 2 better RAM sticks are from NEC in Japan, and are each 64 MB/4d non ECC for PC 800-45, so together they're 128 MB totalNot sure if they are DDRAM or SDRAMThe other 2 green ones are from Taiwan, and are unknown, labeled "ACM R1 00" and "0001 94V-0".Internet search suggests these 2 green ones may be "ACM R1.00 Rambus RDRAM C-RIMM Terminator Continuity Modules"but I don't know for sure what these areI think these sticks were previously used in my old TiVo unit, and I just saved them in a plastic bag when I upgraded to higher memory.They've just been sitting around, so thought it's time to sell themSold as is
