Four green DDR3L ECC RDIMM modules 240-pin 1.35V

OWC

OWC 64GB (4x16GB) DDR3L 1600 CL11 ECC RDIMM 1.35V memory upgrade

SKU CH-1MTP-9C1CE

64 GB DDR3L ECC registered kit with four 16 GB modules at 1600 MHz for compatible Supermicro SuperServer platforms

  • Total capacity64 GB (4 × 16 GB)
  • Rated speedDDR3L 1600 (PC3L 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered

Capacity 64GB (4 x 16GB)

  • ECC registered design protects data integrity in servers
  • 64 GB kit (4 × 16 GB) expands memory capacity for heavy workloads
  • DDR3L 1600 CL11 at 1.35 V lowers power draw versus standard DDR3
  • 240-pin RDIMM form factor fits listed Supermicro SuperServer series
  • 2Rx4 organisation increases rank density for scalable configurations

Server memory kit for Supermicro platforms

This 64GB kit contains four 16GB DDR3L registered DIMMs built for Supermicro SuperServer 4047R, 4048B, 5017GR, 5017R and 5027R systems. It is designed for workstation, server, NAS and router workloads that require ECC protection. The modules will not work in standard desktop computers or alongside unbuffered memory.

DDR3L 1600 CL11 ECC registered specification

Each module runs at 1600 MT/s (PC3L-12800) with CL11 latency at 1.35V. The 240-pin RDIMM format uses 2Rx4 organisation and provides hardware error correction with registered buffering for signal integrity. JEDEC and RoHS compliance ensures the parts meet the original platform qualification.

Low-voltage operation for dense server chassis

At 1.35V the DDR3L modules draw less power than standard DDR3, reducing heat output in fully populated memory banks. No heat spreaders are fitted, allowing tight DIMM spacing in 1U and 2U SuperServer enclosures. Registered buffering also lowers electrical load on the memory controller during sustained workloads.

Questions about this item

What does the 1600 MHz speed mean once the modules are installed in a Supermicro SuperServer?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 latency, delivering the rated throughput when the server's memory controller is set to 1600 MHz.

How does the DDR3L 240-pin registered ECC interface affect compatibility?

These are 240-pin DDR3L ECC registered DIMMs; they only work in systems that support registered ECC DDR3L and will not fit or function in standard desktop boards.

What physical slot and voltage do the 16 GB sticks require?

Each 16 GB module uses a 240-pin DDR3L slot and operates at 1.35 V, matching the Supermicro SuperServer 4047R, 4048B, 5017GR, 5017R and 5027R memory sockets.
