8GB DDR3L 1066MHz ECC RDIMM for Servers

This module delivers 8GB of DDR3L memory at 1066MHz with ECC and registered buffering for server and workstation systems. It operates at a low 1.35V and uses a 240-pin DIMM form factor with a 4Rx8 rank configuration. The CL7 latency supports stable data integrity in multi-module configurations. It replaces specific Hynix part numbers including HMT31GR7AFR8A-G7.

Suits servers requiring registered ECC DDR3L

This memory is built for systems that specifically support DDR3L registered ECC RDIMMs at 1066MHz. It will not work in platforms that require unbuffered UDIMMs, standard 1.5V DDR3, or any other DDR generation. Builders needing higher speeds, different voltages, or non-ECC modules should look at other options.

The registered ECC RDIMM design decides

The module uses a registered buffer and ECC error correction, meaning the motherboard chipset must explicitly support registered DIMMs. A system that only accepts unbuffered memory cannot use this part, regardless of matching speed, voltage, or capacity. Verify your hardware documentation for RDIMM support before purchasing.

Questions about this item

What is included in the box and do I need to buy anything else to install this module?

The box contains one 8GB DDR3L 1066MHz ECC RDIMM 4Rx8 module with 240 pins. No additional parts are required for installation if your server has a free DDR3 DIMM slot.

How do I choose between the listed Hynix part numbers this module replaces?

This single module is a compatible equivalent for all four Hynix part numbers shown — HMT31GR7AFR8A-G7, HMT31GR7BFR8A-G7, HMT31GR7CFR8A-G7 and HMT31GR7EFR8A-G7 — so you do not need to select a specific version.

What does the 1066MHz PC3L-8500 rating mean for real-world server performance?

The module runs at 1066MHz with CL7 latency at 1.35V, delivering PC3L-8500 bandwidth for registered ECC workloads in compatible DDR3L server platforms.
