8GB DDR3L ECC Registered DIMM

This 8GB DDR3L module runs at 1333MHz with CL9 latency and 1.35V operation. It uses a registered 2Rx4 layout with ECC for error correction in server and workstation platforms. The 240-pin DIMM form factor fits standard DDR3 slots designed for registered memory.

Major-brand chipset and lifetime warranty

Modules are built with major-brand chips and tested for reliability before shipment. A lifetime warranty covers the part and US-based technical support is available for installation questions. The kit replaces specific Hynix part numbers including HMT31GR7AFR4A-H9 and related variants.

Verify registered ECC DDR3L support

Confirm your motherboard accepts registered ECC DDR3L DIMMs at 1.35V before ordering. Systems requiring unbuffered non-ECC memory or standard 1.5V DDR3 will not work with this module. Check the qualified vendor list for the exact Hynix part numbers listed to ensure compatibility.

Questions about this item

Will the 2Rx4 registered DIMM need any firmware updates or chip replacement over its service life?

The module uses major-brand chips tested to A-Tech quality standards and carries a lifetime warranty; no firmware updates or chip replacements are required during normal operation.

What limits sustained throughput on this DDR3L 1333 MHz CL9 kit when the server runs at full load?

The PC3L-10600 rating caps peak bandwidth at 10 600 MB/s, so the memory bus itself becomes the bottleneck before the 1.35 V supply or registered buffer saturates.

How much heat and power does the 1.35 V registered ECC module add when the system runs 24/7?

At 1.35 V the DDR3L DIMM draws less power than standard 1.5 V DDR3, reducing thermal output inside a fully populated 240-pin server chassis.
