4 GB DDR3L ECC RDIMM for servers

This 4 GB DDR3L 1600 ECC registered DIMM targets administrators upgrading or repairing compatible server and workstation platforms. It replaces several Hynix part numbers including HMT451R7AFR8A-PB and HMT451V7DFR8A-PB. The single-rank 1Rx8 module uses major-brand chips and operates at 1.35 V low voltage. Buyers who need higher capacity per slot or unbuffered memory should look elsewhere.

Low-voltage operation and registered buffering

Running at 1.35 V reduces power draw compared with standard DDR3 modules while the registered design lightens the electrical load on the memory controller. CL11 latency at DDR3L 1600 delivers stable throughput for typical server workloads. The module is tested for reliable operation under continuous use in multi-DIMM configurations.

240-pin DIMM form factor fits registered slots

The 240-pin DDR3 DIMM installs only in slots wired for registered ECC memory; it will not work in unbuffered desktop boards. One module occupies a single slot, leaving remaining channels available for further expansion. Verify the platform's qualified vendor list before installation to confirm supported speeds and population rules.

Questions sur cet article

How do I install this DDR3L 240-pin ECC RDIMM and what step is often missed?

Align the module notch with the slot key, press firmly until both retention clips click, and verify the system BIOS recognises the registered ECC configuration at 1.35 V.

What maintenance or replacement will this 4 GB DDR3L 1600 module need later?

No scheduled maintenance is required; replace the module only if memory diagnostics report uncorrectable ECC errors or the system fails to POST with this DIMM installed.

What limit appears first when this CL11 1Rx8 RDIMM runs under sustained load?

The registered buffer and CL11 latency set the throughput ceiling at DDR3L 1600 (PC3L-12800), so sustained bandwidth cannot exceed that rated speed.
