Server-grade DDR3 ECC upgrade

This 16 GB DDR3 1333 MHz registered DIMM is built for Supermicro X8QB6 and X8QBE motherboards. It delivers error-correcting, buffered memory for workstations, servers, NAS appliances and routers that require 240-pin PC3-10600 modules. The single 2Rx4 stick installs directly into compatible slots.

Registered DDR3 limits

Registered ECC DDR3 cannot be mixed with unbuffered memory and will not function in standard desktop platforms. The 1333 MHz CL9 JEDEC ceiling caps throughput, so bandwidth-sensitive workloads hit a hard ceiling. Systems needing higher frequencies or newer DDR generations must use different hardware.

Replaces Supermicro MEMDR316LSL05ER13

This module substitutes the Supermicro part number directly, extending the service life of existing X8QB6 or X8QBE infrastructure. The upgrade is worthwhile when current capacity restricts virtualization density or large dataset handling and the platform cannot accept faster memory.

Questions about this item

How do I choose the right capacity if I am populating multiple slots on a Supermicro X8QB6 or X8QBE motherboard?

This module provides 16 GB in a single 240-pin RDIMM. Add one module per available slot up to the board's maximum supported memory.

What real-world throughput can I expect from the PC3-10600 rating once the module is installed in a compatible server?

The PC3-10600 designation corresponds to a peak transfer rate of 10 600 MB/s at 1333 MT/s with CL9 latency.

How does the 240-pin DDR3 ECC Registered interface affect compatibility with my Supermicro X8QBE system?

The 240-pin DDR3 ECC Registered RDIMM fits only server and workstation boards that require registered memory; it will not work in standard desktop systems.
