64GB DDR4-2666 Load Reduced Server Memory

This 64GB DDR4-2666 module is built for HPE servers that require Load Reduced ECC memory. It suits administrators expanding capacity in supported HPE platforms where 4Rx4 registered DIMMs are qualified. The 288-pin form factor matches standard DDR4 server slots.

DDR4-2666 Speed and 1.20V Operation

The module runs at the PC4-21300 data rate with a 1.20V supply. System memory controllers must support the DDR4-2666 JEDEC standard and the Load Reduced electrical interface. Platforms limited to lower speeds or standard Registered DIMMs cannot use this part.

4Rx4 Rank Configuration Decides Compatibility

The 4Rx4 organisation determines whether the server's memory controller can address the full 64GB per slot. Systems qualified only for single-rank or dual-rank modules will not recognise this DIMM. Verify the 4Rx4 Load Reduced requirement in the server's qualified vendor list before ordering.

Questions about this item

Should I choose the 64GB 4Rx4 module or a lower-capacity rank option?

The 64GB 4Rx4 load-reduced module delivers maximum capacity per slot for HPE servers that support LRDIMM population rules; choose it when you need the highest density in each 288-pin DDR4 slot.

What does the DDR4-2666 speed rating mean for actual server performance?

The module operates at 2666 MT/s with a PC4-21300 data rate, providing the throughput your HPE platform expects for memory-intensive workloads when installed in compatible slots.

How does the 288-pin DDR4 interface affect installation and speed limits?

The 288-pin DDR4 form factor fits standard DDR4 DIMM slots and runs at 1.20V; the load-reduced design reduces electrical load so the memory controller can sustain 2666 MT/s across fully populated channels.
