modules (UDIMMs) with Error Checking and Correcting (ECC) technology.
• The minimum system memory is 4 GB.
• The maximum system memory is 64 GB (one 16 GB memory module installed in each of the four memory

• When you install memory modules with different capacity, install the memory module that has the highest
capacity first.
