32GB DDR4 2133 ECC LRDIMM

This 32GB DDR4 2133 ECC LRDIMM module is a load-reduced registered DIMM designed for server and workstation systems. It operates at PC4-17000 speed with CL15 latency and 1.20V voltage. The 4Rx4 rank configuration and major-brand chipset target high-density memory slots in compatible HP platforms.

Suits HP 726722-S21 replacements.

Buyers replacing the HP 726722-S21 part number in qualified servers gain a tested equivalent with ECC error correction and load-reduced buffering. Systems that require standard unbuffered UDIMMs or registered RDIMMs without load reduction cannot use this module. Desktop boards lacking ECC support should look elsewhere.

Tested module with lifetime US support

Each unit undergoes quality-assurance testing before shipment to verify dependable operation in the target platform. A-Tech backs the module with a lifetime warranty and provides complimentary United States-based technical support for compatibility questions before and after purchase. No extra software or cables are bundled.

Questions about this item

Does my server need DDR4 2133 ECC LRDIMM slots to use this 32GB module?

Yes, this module is a 288-pin DDR4 2133 ECC LRDIMM; your system must support Load Reduced DIMMs at that speed and voltage.

Can I mix this 4Rx4 2133MHz stick with existing 2Rx4 DDR4 2133 ECC LRDIMMs?

Mixing ranks is possible if the platform allows it, but the memory controller will run all modules at the lowest common speed and rank configuration.

How do I confirm the 32GB module is detected at 2133MHz with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should show 32GB, 2133MHz, ECC enabled, and LRDIMM type.
