8 GB ECC Registered DDR3 Module

This single 8 GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5 V ECC Registered RDIMM is built for Supermicro X8DTL, X8DTN+, X8DTT, X8DTU and X8OBN motherboards. It targets administrators who need to extend the life of existing server or workstation platforms with validated ECC memory.

Fits Supermicro X8 Series DIMM Slots

The module plugs directly into 240-pin DDR3 registered DIMM slots on the listed Supermicro boards and cannot be mixed with unbuffered memory. It frees the system from relying on slower or mismatched modules while maintaining full JEDEC and RoHS compliance.

Steady Throughput Under Continuous Load

Registered buffering and ECC correction keep data integrity intact during sustained multi-threaded workloads such as virtualization or database tasks. The CL9 latency at 1333 MT/s delivers predictable bandwidth without the variability seen in consumer-grade unbuffered memory.

Questions about this item

Will the CL9 latency at 1333 MHz stay stable when the server runs at full load for hours?

The module is built to JEDEC DDR3 1333 PC3-10600 CL9 timings at 1.5 V, so latency remains at the rated specification under continuous operation.

Does the registered ECC design add noticeable heat or fan noise in a Supermicro X8DTL chassis?

No heat spreader is fitted and the 1.5 V DDR3 registered DIMM draws standard power for its class, so thermal output matches typical server memory without extra cooling noise.

Which motherboard slot and firmware setup do I need before installing this 2Rx4 RDIMM?

A 240-pin DDR3 slot on a Supermicro X8DTL, X8DTN+, X8DTT, X8DTU or X8OBN board with ECC registered support enabled in BIOS is required for the module to function.
