Memory Support

The SYS-5016I-T supports up to 16GB of DDR3 ECC UDIMM or up to 32GB of ECC DDR3 RDIMM (1333/1066/800 MHz in 4 DIMM slots.) Populating these DIMM modules with a pair of memory modules of the same type and same size will result in interleaved memory, which will improve memory performance. Please refer to the table below:

Platform DIMM Type Intel® Xeon® Series Processors
SYS-5016I-T Non-ECC UDIMM Only Not Supported
ECC UDIMM Only Supported (see Table 1)
RDIMM Only (with ECC) Supported (see Table 2)
Mixed ECC with non-ECC Not Supported
Mixed UDIMM/RDIMM Not Supported
Table 1 - DDR3 ECC/Unbuffered (UDIMM) Memory Support
ECC UDIMM 1Gb (x8 DRAM) 2Gb (x8 DRAM)
Single Rank Up to 4GB (4 x 1GB DIMM Modules) Up to 8GB (4 x 2GB DIMM Modules)
Dual Rank Up to 8GB (4 x 2GB DIMM Modules) Up to 16GB (4 x 4GB DIMM Modules)
Quad Rank Not Supported Not Supported
Table 2 -DDR3 ECC Registered (RDIMM) Memory Support
RDIMM 1Gb (x8 DRAM) 2Gb (x8 DRAM)
Single Rank Up to 4GB (4 x 1GB DIMM Modules) Up to 8GB (4 x 2GB DIMM Modules)
Dual Rank Up to 8GB (4 x 2GB DIMM Modules) Up to 16GB (4 x 4GB DIMM Modules)
Quad Rank Up to 8GB (2 x 4GB DIMM Modules) Up to 16GB (2 x 8GB DIMM Modules)
Note: All other memory sizes, types, die, density, that are not listed in these tables are NOT supported.


Memory Population Guidelines

Please follow the tables below when populating the SYS-5016I-T.
DDR3 ECC UDIMM Memory
DIMM Slots per Channel DIMMs Populated per Channel DIMM Type POR Speeds Ranks per DIMM (any combination)
2 1 Unbuffered DDR3 ECC 1066, 1333 Single Rank, Dual Rank
2 2 Unbuffered DDR3 ECC 1066, 1333 Single Rank, Dual Rank
DDR3 ECC RDIMM Memory
DIMM Slots per Channel DIMMs Populated per Channel DIMM Type POR Speeds Ranks per DIMM (any combination)
2 1 Registered DDR3 ECC 1066, 1333 Single Rank, Dual Rank
2 1 Registered DDR3 ECC 1066 Quad Rank
2 2 Registered DDR3 ECC 1066, 1333 Single Rank, Dual Rank
2 2 Registered DDR3 ECC 800* Quad Rank
*Note: 1066 RDIMMs running at 800MHz-BIOS will be automatically downgraded to 800MHz speed.
