Posted January 21, 2017 So currently i have (Samsung (2 x 4GB) PC3L-12800E 2Rx8 DDR3-1600 CL11 Unbuffered Server ECC Memory) in my server and i want to expand to 16GB for more VM, As it would be cheaper upgrade RAM such as addition set of 8GB or 2x4GB but I not able to find any that are the same. It is possible to buy another set of different kits and still work? or should I wait for ZEN and sell my current server than. Magical Pineapples
