64 GB DDR4-2666 LRDIMM for servers

This 64 GB DDR4-2666 Load Reduced DIMM targets HPE server owners who need maximum capacity per slot. The 4Rx4 organisation and 1.20 V operation fit dense memory configurations in supported platforms. ECC and registered signalling protect data integrity in continuous workloads. The module matches HPE part number 882449?001 for drop-in compatibility.

Sustained load behaviour with 4Rx4 organisation

The Load Reduced buffer reduces electrical load on the memory bus, allowing higher densities without slowing the 2666 MT/s data rate under sustained traffic. ECC corrects single-bit errors in real time during long compute runs. Major-brand DRAM from Samsung, SK Hynix or Micron delivers consistent timing across all ranks. Identical modules ship together to keep multi-DIMM channels balanced.

Upgrading from lower-capacity RDIMMs

Replacing smaller RDIMMs with this 64 GB LRDIMM raises total system memory when slot count is fixed. The jump is worth it when applications hit capacity limits rather than bandwidth limits. Buyers who need registered DIMMs without the Load Reduced buffer cannot use this module. Systems that do not support 4Rx4 LRDIMMs at DDR4-2666 will not accept the upgrade.

Questions about this item

How much power does the 1.20V DDR4-2666 module draw when running continuously?

The module operates at 1.20 volts, which is the standard DDR4 voltage, so power draw stays low even under sustained server workloads.

Does my server need a specific motherboard slot to accept this 288-pin LRDIMM?

Yes, the motherboard must provide a DDR4 288-pin DIMM slot that supports Load Reduced memory and 4Rx4 organisation.

Can I mix this 64GB 4Rx4 kit with older 1Rx4 or 2Rx4 DDR4 sticks already in the system?

Mixing different rank counts is not recommended; the memory controller treats each rank separately, so population rules usually require identical rank configurations per channel.
