NEMIX RAM 64GB DDR5 6400MHz ECC RDIMM

This NEMIX RAM module provides 64GB of DDR5 registered ECC memory rated at 6400MHz with CL52 latency. It operates at 1.1V using a 2Rx4 configuration on a 288-pin form factor. The part is built for the Supermicro SYS-222HA-TN server platform using major OEM chips.

Suits Supermicro SYS-222HA-TN capacity upgrades

This module fits administrators expanding memory in a Supermicro SYS-222HA-TN system that requires registered ECC DDR5. It is not suitable for desktops or laptops that accept only unbuffered non-ECC memory. Buyers needing lower voltages or different form factors should look elsewhere.

Registered ECC DDR5 at 6400MHz CL52 1.1V

The registered ECC DDR5 interface running at 6400MHz with CL52 timing and 1.1V operation determines compatibility with the target server memory controller. Verify that your Supermicro SYS-222HA-TN configuration supports this exact speed, rank and voltage before ordering.

Questions about this item

Will the ECC RDIMM modules require any periodic maintenance or component replacement after installation?

No, the registered ECC RDIMM has no moving parts or user-serviceable components, so it runs without scheduled maintenance or replacement intervals.

What limit appears first when the 64GB DDR5 6400MHz CL52 kit runs sustained workloads?

The CAS latency of 52 cycles at 6400MHz sets the timing boundary that governs sustained throughput.

How much heat and power does the 1.1V 2Rx4 module produce during all-day operation?

Operating at 1.1 volts, the 2Rx4 registered DIMM draws minimal power and generates low heat, requiring only standard server airflow.
