16GB DDR3L ECC LRDIMM Server Module

This 16GB DDR3L 1333 ECC Load Reduced DIMM is built for server and workstation platforms that require registered memory with error correction. The single module operates at 1.35V low voltage and uses a 4Rx4 organisation to deliver 16GB capacity in one 240-pin slot. It serves administrators upgrading compatible systems or replacing failed Hynix HMT42GL7BMR4A-H9 sticks.

Suits ECC LRDIMM servers.

The module targets systems that explicitly support DDR3L ECC Load Reduced DIMMs at PC3L-10600 speed. It will not function in consumer desktop motherboards, laptops, or any platform limited to unbuffered non-ECC UDIMMs. Buyers needing standard DDR3 UDIMMs, higher frequencies, or non-ECC memory should select a different product line.

Verify DDR3L LRDIMM support and slot availability

Check the system manual or vendor memory-qualified list to confirm DDR3L 1333 ECC LRDIMM compatibility and maximum supported capacity per slot. Ensure the platform accepts 4Rx4 organisation and 1.35V operation. Confirm an empty 240-pin DIMM socket is available and that the BIOS revision in use recognises Load Reduced modules of this density.

Questions about this item

Does my server motherboard need DDR3L 240-pin LRDIMM slots to use this 16GB module?

Yes, this module is a DDR3L 1333MHz ECC Load Reduced DIMM with a 240-pin interface, so the motherboard must support DDR3L LRDIMM at 1.35V.

Can I mix this 4Rx4 LRDIMM with standard registered DIMMs already installed in my system?

No, Load Reduced DIMMs use a different buffering architecture than standard RDIMMs; the memory controller requires all slots to use the same LRDIMM type.

How can I confirm the module is running at the correct 1333MHz speed and CL9 latency after installation?

Check the BIOS memory information screen or use a system utility such as CPU-Z to verify the reported speed shows 1333MHz (PC3-10600) and CAS latency of CL9.
