HPE Synergy 660 G10 Memory Upgrade

This 32GB DDR4 2666 module is built specifically for the HPE Synergy 660 G10 server. It adds a single 32GB stick of ECC LRDIMM memory to expand system capacity for virtualisation or database workloads. IT teams handling critical enterprise environments can install it to meet growing memory demands.

288-Pin Load Reduced ECC Design

The module uses a 288-pin LRDIMM form factor with 2Rx4 organisation and CL19 latency at 1.20V. Load reduced buffering lowers electrical load on the memory bus, allowing higher density per channel. No heat spreader is fitted, so airflow in dense server chassis remains unobstructed during sustained operation.

Expands From Lower Capacity Configurations

Replacing smaller DDR4 LRDIMM modules with this 32GB stick increases total memory without adding extra slots. The jump is worthwhile when workloads exceed current capacity and the platform supports 2666MHz registered ECC memory. Buyers needing non-ECC or unbuffered DIMMs for desktop platforms should look elsewhere.

Questions about this item

What DDR4 speed and PC4 rating does this LRDIMM run at?

This module operates at DDR4 2666 with a PC4-21300 data rate.

What physical slot and pin count does the 288-pin LRDIMM require?

It fits a standard 288-pin DDR4 DIMM slot on the HPE Synergy 660 G10 server motherboard.

How is the module seated and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the server BIOS recognises the full 32 GB capacity.
