16GB DDR3 1600 ECC Registered Module

This 16GB DDR3 1600 module delivers ECC Registered operation for server platforms that require error correction and signal buffering. The 2Rx4 organisation and CL11 latency support stable throughput in multi-channel configurations. It is built for administrators who need registered memory to populate high-capacity slots in compatible systems.

Replaces non-ECC or unbuffered DDR3

The jump is worthwhile when your motherboard mandates registered DIMMs and ECC protection for data integrity. Standard unbuffered or non-ECC modules will not function in these slots, so this kit enables the capacity and reliability the platform expects. It suits upgrades where registered memory is a hard requirement rather than an option.

Verify 240-pin DDR3 registered support

Confirm the system accepts 240-pin DDR3 registered DIMMs at 1.50V and can address 16GB per slot with 2Rx4 density. The board must support quad-channel population rules for this kit to operate as intended. Without registered memory support, the modules will not post.

Questions about this item

Will this 240-pin DDR3 DIMM fit my server's memory slots?

The module uses the standard 240-pin DDR3 form factor and 1.50V voltage; verify your server accepts registered ECC DDR3 1600 before installing.

How do I install this registered ECC module correctly?

Power down the server, open the chassis, align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then power on to confirm detection.

What maintenance or replacement should I expect for this 16GB kit?

No routine maintenance is required; if a module fails, replace it with an identical 16GB DDR3 1600 CL11 registered ECC 2Rx4 DIMM to preserve quad-channel operation.
