Samsung 64 GB DDR4-2400 Registered ECC Module

This 64 GB DDR4-2400 LP ECC TSV RDIMM is built for servers and workstations that require registered, error-correcting memory. The 4Rx4 organisation and low-profile height suit dense multi-DIMM configurations. It operates at 1.20 V and carries Supermicro certification for validated compatibility.

Compatibility Check Before Ordering

Verify that your motherboard supports 288-pin DDR4 registered ECC RDIMMs at 2400 MT/s and can address 4Rx4 modules. Confirm the platform accepts 1.20 V operation and that the BIOS recognises TSV stacking. Systems limited to unbuffered UDIMMs or lower rank counts will not work with this module.

Thermals Noise and Power Draw

Low 1.20 V voltage reduces power consumption per module compared with higher-voltage DDR4 variants. The registered buffer adds negligible latency while improving signal integrity in fully populated channels. Passive cooling in normal server airflow keeps temperatures within specification without audible fan noise from the memory itself.

Perguntas sobre este artigo

Does the single 64GB DDR4-2400 LP ECC TSV RDIMM ship alone, or are extra parts required?

The module arrives as one 288-pin registered DIMM; no additional components are needed for installation.

When would I pick this 4Rx4 64GB stick instead of a lower-capacity or dual-rank alternative?

Choose it when the server board supports 4Rx4 registered ECC and you need maximum density per slot at 2400 MT/s.

What does the 2400 MT/s rating deliver once the RDIMM is seated in a compatible system?

It provides a peak transfer rate of PC4-19200 bandwidth at the standard 1.20 V DDR4 voltage.
