DIMM slots: 4
DIMM type: unbuffered DDR1/400 ECC DIMMs (128 bit plus ECC databus)
DIMM size: 512-MB, 1-GB or 2-GB
Maximum capacity: 8GB
NOTE: Pairs of different densities may be mixed, e.g. 2×512MB and 2×1GB.
Install a single DIMM in any slot.
Single DIMM memory configurations are supported, but a three DIMM memory configuration is not supported.
Install the first DIMM pair in slots DIMM 1 and DIMM 2.
Install the second DIMM pair in slots DIMM 3 and DIMM 4.
The following rules apply when configuring memory in your Sun Fire X2100 Server.
The Sun Fire X2100 Server contains four DIMM slots, numbered DIMM1, DIMM2, DIMM3, and DIMM4. DIMM1 is the slot closest to the CPU.
The four slots are divided into two banks, Bank0 and Bank1. Bank0 is comprised of DIMM slots 1 and 2, and Bank1 is comprised of DIMM slots 3 and 4.
The DIMM slots are color-coded. The Bank0 slots are blue, and The Bank1 slots are black.
When configuring the memory slots, populate the blue slots first, before populating the black slots.
The system supports 1, 2, or 4 DIMM configurations.
When configuring for 2 or 4 DIMMs, the DIMMs must be installed as matched pairs. The two DIMMs in a bank must be identical (same size, type, and manufacturer).
Supported DIMM size and type:
Supported DIMM sizes are: 512 MB, 1 GB, and 2 GB.
Supported DIMM type is: DDR1/400 Unbuffered ECC (128 bit plus ECC databus).
Minimum and Maximum Memory Configurations:
The minimum memory configuration is 512 MB, one 512 MB DIMM in slot1.
The maximum memory configuration is 8 GB, four 2 GB DIMMs, one 2 GB DIMM in each slot.
