memory modules (DDR3 LV RDIMMs).
• Each slot supports 4 GB, 8 GB, and 16 GB 1333 MHz DDR3 RDIMMs.
• Each slot supports 2 GB and 4 GB 1333 MHz DDR3 unbuffered dual inline memory modules (UDIMMs)
with Error Checking and Correcting (ECC) technology.
• Your server supports up to six memory modules when one microprocessor is installed and up to 12
memory modules when two microprocessors are installed.
