OWC 1R6D32R4032P 32GB (2x16GB) DDR3 1600 CL11 ECC Registered RDIMM memory upgrade

SKU CH-5M0F-74MWX

A 32GB dual-channel kit of registered ECC DDR3 1600 memory for Supermicro X9 workstation and server boards

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR3 1600 (PC3 12800)
  • CAS latencyCL11
  • Rated voltage1.5 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 32GB (2 x 16GB)

  • 32GB capacity for heavy server workloads using 2 x 16GB modules
  • ECC registered design protects data integrity in workstation environments
  • DDR3 1600 CL11 speed matches Supermicro X9 series specifications
  • 5V operation meets JEDEC standard for registered DIMMs
  • 240-pin 2Rx4 form factor fits qualified Supermicro motherboards

Targeted Server Upgrade

This 32GB kit delivers two 16GB DDR3 1600 registered ECC modules built for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. It is intended for administrators extending the service life of compatible workstations, servers, NAS appliances or routers that require registered memory.

Registered DDR3 Constraints

The modules operate at 1.5V with CL11 latency and a 2Rx4 organisation on a 240-pin interface. Registered ECC memory cannot be mixed with unbuffered DIMMs and will not function in standard desktop platforms that lack registered memory support.

Replaces Supermicro MEMDR316LHL01ER16

The kit directly substitutes those part numbers when a 32GB capacity increase is needed. The upgrade is worthwhile when the target system supports registered DDR3 and the workload benefits from additional ECC capacity.

Questions about this item

Should I pick the 32 GB kit or a smaller capacity for my Supermicro X9SRi board?

The kit provides 32 GB total as two 16 GB modules; choose it when your workload needs that much ECC registered memory and the board has free 240-pin slots.

What does the 1600 MHz rating mean once the modules are installed in a server?

The modules run at DDR3 1600 with CL11 latency at 1.5 V, giving the platform its rated PC3-12800 data rate when the memory controller is set to that speed.

How does the 240-pin registered ECC interface limit what I can mix with these DIMMs?

They are 2Rx4 registered ECC DDR3 DIMMs, so they cannot be mixed with unbuffered or non-ECC modules and require a chipset that supports registered memory.
