32GB DDR4-2133 ECC LRDIMM for servers

This 32GB DDR4-2133 module uses Load Reduced ECC technology to support high-density server configurations. It is intended for administrators expanding memory in qualified Supermicro platforms that require registered LRDIMM population. The PC4-17000 rating confirms the 2133 MT/s data rate at 1.20V. It is not for desktop boards that accept only unbuffered UDIMMs.

288-pin installation with qualified motherboard

Installation follows standard 288-pin DDR4 keying, but the module must be paired with a motherboard qualified for Load Reduced DIMMs and the correct population sequence. Errors typically arise when mixing LRDIMMs with standard RDIMMs or populating slots in an unsupported order. Verify the platform memory guide before seating the module.

Sustained load stability at 1.20V

Under continuous workloads the LRDIMM buffer reduces electrical loading on the memory bus, helping maintain signal integrity at the rated 2133 MT/s. ECC corrects single-bit errors in real time, preventing data corruption during long compute runs. The 1.20V operating voltage supports consistent throughput without exceeding the DDR4 standard voltage envelope.

Questions sur cet article

How can I confirm the 32GB DDR4-2133 ECC LRDIMM is running correctly after installation?

Enter the server BIOS or UEFI and verify the module shows 32GB capacity, 2133 MT/s speed, 1.20V voltage and ECC Load Reduced status.

What comes with the HMA84GL7MMR4N-TF module and what must I source separately?

The box contains the single 288-pin DDR4 LRDIMM; any additional DIMMs, CPU heatsinks or motherboard standoffs are not included.

Which Supermicro certified version matches the MEM-DR432L-HL01-LR21 part number?

The MEM-DR432L-HL01-LR21 code identifies this exact 32GB DDR4-2133 ECC Load Reduced DIMM; no other capacity or speed variant shares that part number.
