Capacity and purpose

This 64GB DDR4-2666 ECC LRDIMM is built for servers that need maximum memory density per slot. The load-reduced design and 4Rx4 organisation let administrators reach high capacities while keeping the electrical load on the memory bus low. It targets IT teams extending the life of existing HP-compatible platforms without replacing hardware.

Compatibility checks

Verify that your server accepts 288-pin DDR4 LRDIMMs running at 1.20V and supports 4Rx4 modules at the PC4-21300 data rate. The motherboard and BIOS must be qualified for load-reduced ECC memory of this rank configuration; registered RDIMMs and standard unbuffered DIMMs are not interchangeable with this part. Cross-reference the HP part number 840759-191 against your system's qualified vendor list before ordering.

What the bundle changes

The module ships as a standalone memory stick with no cables, brackets, software licences or documentation beyond the standard label. Installation adds 64GB of ECC-protected capacity immediately, reducing swapping and allowing more virtual machines per host. No firmware updates or driver packages are included or required for the memory itself.

Questions about this item

Does the 64GB DDR4-2666 LRDIMM arrive as a single module or must additional sticks be purchased to reach the stated capacity?

The product is a single 64GB 288-pin DDR4 LRDIMM; no extra modules are required to obtain the full 64GB capacity.

Should I select the 4Rx4 1.2V version or look for a different rank and voltage combination for my HP server?

This module is built to the HP 840759-191 specification — 4Rx4 organisation, 1.20V operation, ECC and load-reduced buffering — so choose this version when your service manual calls for that exact configuration.

What does the PC4-21300 rating mean for actual throughput once the DIMM is installed in a compatible HP system?

PC4-21300 indicates a peak transfer rate of 21300 MB/s at 2666 MT/s; real-world bandwidth will be slightly lower due to protocol overhead and memory-controller scheduling.
