128GB DDR4-2400 LRDIMM for servers

This 128GB DDR4-2400 module uses an 8Rx4 load-reduced design with registered ECC operation at 1.2V. It targets administrators expanding memory capacity in compatible HP server platforms. The PC4-19200 rating supports standard DDR4-2400 bus speeds. Major-brand DRAM components ensure OEM-level reliability.

Sustained load behaviour with CL15 timing

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded workloads. The 8Rx4 organisation allows higher density per channel without increasing electrical load on the memory controller. CAS latency of 15 cycles provides deterministic access timing for virtualisation and database tasks. Voltage remains at 1.20V under sustained utilisation.

Installation notes for 8Rx4 LRDIMM modules

Load-reduced DIMMs install like standard registered modules but require platform support for the 8Rx4 rank structure. Verify the server BIOS and memory configurator accept this rank count before deployment. Mixing with different rank configurations can prevent POST or reduce usable capacity. No special tools are required beyond standard anti-static precautions.

Questions about this item

What is the operating voltage of this 128GB LRDIMM under sustained server loads?

The module operates at 1.2V, matching the standard DDR4 voltage for this speed grade.

Does the motherboard need to support LRDIMM and 8Rx4 organisation for this module to function?

Yes, the platform must accept DDR4 LRDIMMs with an 8Rx4 configuration; standard RDIMM-only boards will not recognise it.

Can this 2400MHz CL15 module run in a system currently populated with slower DDR4 LRDIMMs?

All installed modules will operate at the speed of the slowest kit present, so faster sticks automatically downclock to match.
