Capacity 128GB (4 x 32GB)

  • ECC registered design protects data integrity in servers
  • 128GB kit with four 32GB modules maximises capacity
  • DDR3 1600 CL11 speed matches system requirements
  • 240-pin registered form factor fits Supermicro X9 boards
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server ECC RDIMM Kit

This 128GB kit contains four 32GB DDR3 1600 registered ECC modules built for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW motherboards. The 4Rx4 organisation and CL11 timing at 1.5V match the JEDEC PC3-12800 specification for workstation and server platforms. It is not compatible with standard desktop computers or unbuffered memory.

Registered 240-Pin Upgrade

Each module uses a 240-pin DDR3 interface and registered signalling to reduce electrical load on the memory controller. The kit frees all four DIMM slots on supported boards for a single high-capacity installation without mixing ranks. Buyers who need unbuffered DIMMs or a different voltage must choose another product.

JEDEC Compliant Modules

The modules are 100% JEDEC and RoHS compliant, delivering a warranty-safe upgrade that meets OEM specifications. No heat spreaders are included, so airflow in dense server chassis remains unaffected. Users requiring RGB lighting or consumer overclocking profiles will not find them here.

Questions about this item

What is the CAS latency of the DDR3 1600 modules under sustained load?

The modules run at CL11 timing, which is the rated latency for DDR3 1600 operation.

How much power does the 1.5 V registered kit draw when the server runs all day?

Each DIMM operates at 1.5 V; the registered buffer adds a small overhead compared with unbuffered DDR3.

Which motherboard series must I already own for this 4Rx4 kit to work?

The kit is validated for Supermicro X9SRG, X9SRH, X9SRi, X9SRL and X9SRW series motherboards.
