Server Memory Upgrade

This 4GB DDR3 1866MHz ECC RDIMM module is designed for server and workstation systems that require registered memory with error correction. It replaces the Hynix HMT351R7EFR4C-RD part number and fits 240-pin DIMM slots operating at 1.5V standard voltage. The single-rank 1Rx4 organisation uses major-brand chipsets to deliver dependable capacity for compatible platforms.

Sustained Load Behaviour

Registered buffering and ECC circuitry maintain data integrity during continuous workloads such as virtualisation, database tasks or long rendering jobs. The CL13 latency and PC3-14900 bandwidth provide steady throughput without the error accumulation that can affect non-ECC modules under prolonged stress. Testing validates reliable operation across extended duty cycles in qualified systems.

Thermals and Power

Standard 1.5V DDR3 voltage keeps power draw consistent with the DDR3 specification for registered DIMMs. The module operates within normal server thermal envelopes without requiring additional airflow beyond typical chassis cooling. No exotic cooling or elevated voltage is needed, so acoustic profile matches other registered memory in the same chassis.

Questions sur cet article

How much heat and power does a 1.5 V DDR3 1866 MHz registered DIMM add when running continuously?

At the standard 1.5 V DDR3 voltage this 4 GB module draws only modest power, so heat output stays low enough for normal server airflow even under all-day workloads.

What motherboard slot and memory controller features are required to use this 240-pin ECC RDIMM?

You need a DDR3 DIMM socket that accepts 240-pin registered modules and a memory controller that supports ECC and registered operation.

Can this DDR3 1866 MHz CL13 1Rx4 module share a channel with older DDR3 DIMMs of different speed or rank?

Yes, the memory controller will down-clock all modules to the slowest speed and highest latency present, so mixing is possible but overall bandwidth drops to the lowest common spec.
