128GB DDR4 2666 LRDIMM for servers

This 128GB DDR4-2666 ECC LRDIMM is built for HP-compatible server platforms that require maximum memory density per slot. It targets administrators extending the life of existing infrastructure by fully populating memory channels without replacing the chassis. The load-reduced design reduces electrical load on the memory controller, allowing higher capacities than standard RDIMMs. It suits virtualisation hosts and database servers where capacity per module matters more than frequency.

Sustained throughput with load-reduced architecture

The 8Rx4 organisation and 1.2V operation keep power draw stable while the load-reduced buffer absorbs signalling stress during continuous workloads. ECC corrects single-bit errors in flight, preventing silent data corruption during long compute runs. PC4-21300 bandwidth feeds multi-socket CPUs without bottlenecks when all channels are populated. Thermal output remains predictable because the buffer spreads current across ranks rather than concentrating it on the controller.

288-pin installation with HP compatibility guarantee

The module follows the standard 288-pin DDR4 LRDIMM form factor and keys into any slot wired for this specification. Compatibility is validated against the HP Q7D83A part number, so the server BIOS recognises the SPD data without manual configuration. The most common issue is mixing LRDIMMs with RDIMMs in the same channel, which the platform firmware will reject at POST. Populating identical modules per channel avoids that error.

Questions sur cet article

How much power does the 1.2V LRDIMM draw when the server runs continuously?

Each module operates at 1.20V; total power depends on how many 128GB sticks the platform populates and the CPU memory-controller load.

What must the motherboard provide for this 288-pin DDR4 LRDIMM to function?

A DDR4 2666 (PC4-21300) registered DIMM slot with an 8Rx4-capable memory controller and ECC enabled in BIOS.

Can this 8Rx4 module share a channel with standard 1Rx4 or 2Rx4 RDIMMs?

Mixing 8Rx4 load-reduced DIMMs with lower-rank registered DIMMs in the same channel is not supported by the memory controller.
