The maximum memory that is supported on your system varies according to the types and sizes of memory modules being used:
•
4 GB, 8 GB, and 16 GB are supported for a total of up to 128 GB.
•1 GB, 2 GB, and 4 GB UDIMMs are supported for a total of up to 32 GB.
General Memory Module Installation Guidelines
To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory.
NOTE: Memory configurations that fail to observe these guidelines can prevent your system from starting and producing any video output.
•1.35 V DDR3L memory operates the memory modules at 1.5 V, if any of the following conditions exist:
–Two 1333 MHz DIMMs per channel.
–A combination of both standard and low voltage memory modules.
•RDIMMs and UDIMMs cannot be mixed.
•Except for memory channels that are unused, all populated memory channels must have identical configurations.
•The memory configuration for each processor must be identical.
•Memory modules of different sizes can be mixed in
•For Optimizer Mode, memory modules are installed in the numeric order of the sockets beginning with A1 or B1.
•The memory speed of each channel depends on the memory configuration:
–For single rank memory modules:
•One memory module per channel supports up to 1333 MHz.
•Two memory modules per channel support up to 1333 MHz.
