128GB DDR4 2933 ECC LRDIMM for HP Synergy

This 128GB DDR4 2933 CL21 4Rx4 288-pin 1.2V ECC Load Reduced DIMM is built for HP Synergy 480 Gen10 and 660 Gen10 servers. It targets administrators who need maximum capacity per slot in dense compute modules running virtualisation or database workloads.

Fits HP Synergy compute modules.

The module fits 288-pin DDR4 slots in Synergy 480 Gen10 and 660 Gen10 bays and must not be mixed with unbuffered or registered ECC DIMMs. Backward compatibility with 2133, 2400 and 2666MHz bus speeds lets it slot into existing memory configurations without a full refresh.

Sustained load behaviour

Load-reduced buffering lowers electrical load on the memory controller so all ranks stay active during long-running jobs. ECC corrects single-bit errors on the fly, keeping data integrity intact through extended uptime. 1.2V operation limits thermal output while the module runs at its rated 2933MHz speed.

Questions about this item

Will a single 128GB 4Rx4 module hit the rank-per-channel limit on the Synergy 480 Gen10?

Each 4Rx4 LRDIMM presents four logical ranks to the memory controller; the Synergy 480 Gen10 supports up to eight ranks per channel, so one module leaves headroom for a second DIMM in the same channel.

How much heat does the 1.2V 2933MHz LRDIMM generate under continuous load?

At 1.2V the module draws minimal power; load-reduced buffering reduces electrical loading on the bus, so sustained operation stays within normal server DIMM thermal limits without a heat spreader.

Which HP Synergy compute module must already be installed for this memory to work?

This DDR4 2933 ECC LRDIMM is validated for the HP Synergy 480 Gen10 and 660 Gen10 compute modules; one of those must be present in the frame.
