Server ECC UDIMM for Hynix replacement

This A-Tech 4 GB module is a direct equivalent for Hynix HMT351U7CFR8A-PB and HMT351U7EFR8A-PB parts. It targets administrators who need to add or replace DDR3L ECC memory in compatible server or workstation platforms without changing voltage or form factor.

240-pin DDR3L 1.35 V unbuffered design

The stick uses a standard 240-pin DIMM edge connector and operates at 1.35 V, matching the low-voltage DDR3L specification. Unbuffered ECC topology with 2Rx8 organisation means it slots straight into boards that accept UDIMM ECC modules, leaving registered DIMM slots for other configurations.

Upgrades non-ECC or lower-capacity DDR3L UDIMMs

Replacing non-ECC DDR3L UDIMMs with this module adds error correction for data integrity in always-on workloads. The jump is worthwhile when the platform supports ECC UDIMM and the current population leaves free 240-pin slots for the 4 GB capacity increase.

Questions sur cet article

What DDR standard and peak transfer rate does this DDR3L 1600 module use?

This module uses the DDR3L standard at 1600 MHz with a PC3L-12800 rating, capping the peak transfer rate at that specification.

What physical slot and pin count does this 240-pin DIMM require?

It fits a standard DDR3 DIMM slot with 240 pins and the low-profile UDIMM form factor used in servers and workstations.

How is this ECC UDIMM installed and what step is often missed?

Power down, open the chassis, align the notch on the 240-pin edge connector with the slot key, press firmly until both retention clips click, then enable ECC in the system BIOS.
