Green 240-pin DDR3 RDIMM module with black memory chips, no heat spreader

OWC

OWC 1R6D31R408GB 8GB DDR3 1600 ECC Registered RDIMM memory upgrade

SKU CH-44B1-9BCV7

An 8 GB DDR3-1600 ECC registered RDIMM for Supermicro X9SR-series workstation and server motherboards

  • Capacity8GB
  • Type240-Pin DDR3 ECC RDIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCYes

Capacity 8GB

  • ECC protection prevents data errors in servers
  • Registered design stabilises heavy multi-module loads
  • DDR3 1600 speed matches system bus timing
  • CL11 latency keeps response times tight
  • Validated for Supermicro X9SRG, X9SRH, X9SRi, X9SRL, X9SRW

Targeted Server Upgrade

This 8GB DDR3 ECC Registered RDIMM is built for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. It runs at 1600MHz with CL11 latency and 1.5V operation. The module uses a 240-pin 1Rx4 configuration without a heat spreader. It replaces Supermicro part MEMDR380LSL04ER16 for direct compatibility.

Workstation And Server Only

This memory suits administrators extending the life of existing DDR3 server platforms or building cost-effective replacement nodes. It will not work in standard desktop computers or consumer laptops. Buyers who need unbuffered DIMMs or a different DDR generation must select a different product line.

Registered ECC Requirement

The single deciding specification is the Registered ECC design combined with the DDR3 1600 standard. Only systems that explicitly support Registered ECC DDR3 DIMMs can use this module; any board requiring unbuffered or non-ECC memory will reject it.

Highlights

  • ECC protection prevents data errors in servers
  • Registered design stabilises heavy multi-module loads
  • DDR3 1600 speed matches system bus timing
  • CL11 latency keeps response times tight
  • Validated for Supermicro X9SRG, X9SRH, X9SRi, X9SRL, X9SRW

Questions about this item

Should I choose the 8 GB single module or look for a larger capacity kit?

This listing is a single 8 GB DDR3 1600 ECC registered RDIMM. If your Supermicro X9 series board has free 240-pin slots, add one module per channel to keep ranks balanced.

What does the 1600 MHz speed rating deliver once installed in a Supermicro X9 server?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at 1.5 V, giving the maximum bandwidth the X9 chipset memory controller supports for registered DIMMs.

How does the DDR3 240-pin registered ECC interface limit what I can mix with this module?

The 240-pin registered ECC design only works in server or workstation boards that support registered memory; it cannot be mixed with unbuffered DIMMs and will not fit desktop platforms.
