Axiom 64GB DDR4-2400 ECC LRDIMM

This 64GB DDR4-2400 module is built for servers that require error-correcting, load-reduced memory. It suits administrators expanding capacity in compatible HP platforms. The registered design helps maintain signal integrity on heavily populated motherboards. Buyers needing non-ECC or standard unbuffered DIMMs should look elsewhere.

Load-reduced DDR4 at CL15 1.20V

The single specification that decides fit is the load-reduced ECC architecture combined with CL15 latency at 1.20V. This module operates as PC4-19200 on a 288-pin DDR4 interface. Systems that require standard registered RDIMMs or different voltage levels will not accept this part. Verify the motherboard qualification list before purchase.

Thermals noise and power draw

Load-reduced modules typically run cooler per gigabyte than standard registered DIMMs because the memory buffer reduces electrical loading on the bus. At 1.20V the power draw per module remains modest for high-density server deployments. No active cooling is required on the DIMM itself; airflow across the memory slots is sufficient. Acoustic output is silent as there are no moving parts.

Questions about this item

How does the 64 GB capacity affect real workloads?

The 64 GB module lets a compatible server hold more virtual machines or larger in-memory datasets without swapping to storage, improving throughput for memory-bound applications.

What does the DDR4 2400 (PC4 19200) rating mean for actual bandwidth?

The DDR4 2400 rating indicates 2400 million transfers per second on a 64-bit bus, and the PC4 19200 designation reflects the resulting peak transfer rate.

Will the 288-pin LRDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 LRDIMM form factor, so it installs in any server slot wired for DDR4 load-reduced DIMMs.
