DDR3 ECC RDIMM for Hynix replacement

This 4 GB DDR3 registered DIMM operates at 1333 MHz with CL9 latency and 1.5 V power. It uses a 2Rx4 organisation and carries ECC for error correction in server and workstation platforms. The module is built as a compatible equivalent for the Hynix HMT351V7BMR4C-H9 part number. All units are tested for reliability before shipment.

Suited for servers needing registered ECC DDR3

Administrators upgrading or repairing systems that require registered ECC memory at the PC3-10600 speed grade will find this module a direct fit. Builders whose platforms accept only unbuffered UDIMMs, or those requiring a different voltage, speed, rank configuration or DDR generation, should select a module matching those specifications. Verify the motherboard qualified-vendor list before ordering.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC circuitry allow the memory controller to address larger capacities while detecting and correcting single-bit errors. Systems that mandate registered DIMMs and a 2Rx4 rank layout will recognise this module; platforms limited to unbuffered memory or a different rank structure will not support it. Check the system documentation for the required registration and rank combination.

Questions about this item

Will the 240-pin DDR3 DIMM slot wear out and need replacement?

The 240-pin DDR3 DIMM socket is a passive connector rated for many insertion cycles; it does not wear out under normal server operation and requires no scheduled replacement.

What limits sustained throughput on this CL9 1333 MHz module?

The CL9 latency at 1333 MHz sets the maximum sustained bandwidth; the memory controller cannot push data faster than the rated PC3-10600 ceiling.

How much heat does a 1.5 V registered ECC module produce running 24/7?

At 1.5 V the module draws standard DDR3 power; registered ECC operation adds minimal overhead, so a normal server airflow path keeps temperatures within spec.
