32GB DDR3L Load Reduced Module

This 32GB HPE server memory module uses 240-pin DDR3L technology at 1866 MT/s with a CL13 latency. It is built for compatible HPE ProLiant systems that require load-reduced DIMMs to maximise installed capacity.

Suited for capacity-focused upgrades

The 4Rx4 organisation and load-reduced design let supported platforms populate more slots without exceeding electrical loading limits. It is not for systems that accept only standard registered or unbuffered DDR3 modules.

Refurbished condition with standard packaging

The module ships as a refurbished unit tested to HPE specifications. No additional accessories, heat spreaders or software licences are included beyond the memory stick itself.

Questions about this item

Which server motherboard slot and memory generation do I need for this 240-Pin DDR3L 1866 module?

The module fits a 240-pin DDR3 socket and runs at DDR3L 1866 (PC3L 14900) with CAS latency 13; the board must support DDR3L Load Reduced DIMMs.

Can I mix this 4Rx4 Load Reduced DIMM with standard Registered DDR3L sticks already in my system?

Load Reduced and standard Registered DIMMs use different electrical buffering; mixing them is not supported and will prevent the server from posting.

How do I confirm the 32 GB module is recognised at the correct 1866 MT/s speed after installation?

Enter the BIOS or UEFI on boot and verify the memory information shows 32 GB, 1866 MT/s, CL13 and Load Reduced rank 4Rx4 for the installed slot.
