What ECC type memory (RAM) do I need?
Non-ECC Unbuffered (or simply Non-ECC): Primarily used in Desktop PCs, Laptops, All-in-One (AIO) computers, & Mini PCs as almost all those system types only support Non-ECC Unbuffered memory
ECC Registered: Only used in Servers and select Workstations
ECC Load Reduced: Only used in Servers and select Workstations
ECC Unbuffered: Only used in Servers and Workstations
ECC Fully Buffered: Only used in select Servers that support DDR2 RAM
Different ECC types cannot be mixed within the same system, only one type can be used.
