2GB DDR3 1333 ECC Registered module

This 2GB DDR3 1333 ECC Registered module is built for servers and workstations that require error-correcting, registered memory. It operates at 1.50V with CL9 latency and includes a thermal sensor for platform monitoring. The single-rank x4 organisation suits density-limited DIMM slots.

Upgrade from non-ECC or unbuffered DDR3

Replacing non-ECC or unbuffered DDR3 with this registered ECC module adds data-integrity protection and reduces electrical load on the memory controller. The jump is worth it when the platform mandates registered DIMMs and the workload cannot tolerate silent data corruption.

DDR3 1333 registered platform limits

DDR3 1333 registered memory tops out at the 1333 MT/s data rate and 1.50V operation defined by the JEDEC standard for this generation. Platforms that require higher frequencies, lower voltages or unbuffered signalling cannot use these modules. Capacity per DIMM is limited by the DDR3 architecture and the registered buffer design.

Questions about this item

Will the 240-pin DDR3 module fit my server's DIMM slots?

The module uses the standard 240-pin DDR3 form factor, so it fits any server motherboard slot designed for DDR3 registered memory.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, and verify the thermal sensor contacts the motherboard pad — this last step is frequently overlooked.

When should I consider replacing this 2GB DDR3 1333 module?

Replace it if memory diagnostics report correctable ECC errors that become uncorrectable, or if the server fails to recognise the full 2GB capacity during POST.
