16GB DDR3L ECC RDIMM for Servers

This 16GB registered DDR3L module runs at 1333MHz with CL9 latency and 1.35V operation. It uses a 4Rx4 organisation and major-brand chips on a 240-pin DIMM. The stick is built for server and workstation platforms that require ECC error correction and registered signalling.

Replaces Hynix HMT42GR7A/B/CMR4A-H9

The module is a direct equivalent for three specific Hynix part numbers used in compatible systems. Swapping to this unit makes sense when a slot is empty or a failed stick must be replaced with an identical-capacity registered DIMM. Builders expanding beyond the board’s supported rank-per-channel limit should verify the manual first.

DDR3L voltage and registered signalling limits

The 1.35V low-voltage standard reduces power draw but requires a memory controller that explicitly supports DDR3L. Registered buffering adds a clock cycle of latency and restricts maximum module count per channel. Systems limited to unbuffered UDIMMs or higher-voltage DDR3 cannot use this memory.

Questions about this item

Will this 240-pin DDR3L module fit my server's RDIMM slots?

Yes, the module uses the standard 240-pin DIMM form factor and registered DDR3L interface required for compatible server RDIMM slots.

What is the correct seating procedure for this registered ECC module?

Align the notch with the slot key, press firmly until both side latches click shut, and verify the system detects the full 16GB capacity at 1333MHz.

Does the 1.35V DDR3L voltage require any future adjustment or replacement?

No, the 1.35V low-voltage specification is fixed; the module runs at this voltage for its lifetime without needing adjustment or scheduled replacement.
