Server DDR3 ECC RDIMM

This 16 GB DDR3 1600 MHz module uses a registered DIMM design with ECC and a 2Rx4 layout. It operates at the standard 1.5 V and carries a CL11 latency rating. The 240-pin form factor fits compatible server and workstation platforms that require registered memory.

Direct Crucial replacement

The module is specified as a compatible equivalent for the Crucial CT204872BB160B part number. Buyers replacing that exact SKU can use this unit without changing any other component. No bundled software, cables or heatsinks are included with the memory stick.

Verify registered DIMM support

Confirm that your motherboard and processor support DDR3 registered ECC DIMMs before ordering. Systems that accept only unbuffered non-ECC memory will not work with this module. Check the maximum supported capacity per slot and the total number of available 240-pin slots in your chassis.

Questions about this item

Will the registered ECC RDIMM design or 2Rx4 rank layout require any special maintenance or replacement steps later?

No special maintenance is needed; the registered ECC RDIMM with 2Rx4 organisation operates like standard server memory and is replaced only if a module fails.

What limit appears first when this 16 GB DDR3 1600 MHz CL11 module runs under sustained load?

The DDR3 1600 MHz speed and CL11 latency set the bandwidth and response ceiling before thermal or voltage limits are reached.

How much heat or power does the 1.5 V DDR3 DIMM produce when it runs all day in a server?

At the standard 1.5 V DDR3 voltage the module draws typical DDR3 power and generates normal server-memory heat, requiring only standard chassis airflow.
