SUPER MICRO Computer 5015M-UR, 5015M-NTR Memory Support, Installing Dimm into Slot

SUPERSERVER 5015M-UR/5015M-U/5015M-NTR/5015M-NT User's Manual

Memory Support

The PDSMU supports up to 8 GB of unbuffered ECC/non-ECC DDR2-667/533/400 SDRAM. Interleaved memory requires modules of the same size and speed to be installed in pairs. Do not mix DIMMs of different sizes and speeds. Notes: Due to OS limitations, some operating systems may not show more than 4 GB of memory. Due to memory allocation to system devices, memory remaining available for op- erational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (Refer to the table below for details.)
