Direct Hynix Replacement

This A-Tech 4 GB DDR3 module is built as a drop-in equivalent for Hynix HMT151R7AFP4C-H9, HMT151R7BFR4C-H9 and HMT151R7TFR4C-H9 parts. It targets administrators upgrading or repairing registered-ECC server and workstation platforms that require 240-pin DDR3 1333 MHz memory.

Registered ECC DIMM for Multi-Module Arrays

The 2Rx4 registered design places a register on the command bus, reducing electrical load on the memory controller so larger populations of DIMMs can run stably at 1.5 V. Systems that accept unbuffered UDIMMs or non-ECC memory cannot use this module; verify the platform specifically supports registered ECC RDIMMs before installation.

Tested Module with Lifetime Coverage

Every stick passes A-Tech’s validation suite before shipping, ensuring the major-brand chips meet the stated CL9 latency and PC3-10600 timing. A lifetime warranty and US-based technical support are included, giving administrators a direct path for troubleshooting or replacement if a fault appears in service.

Questions about this item

Does the registered design and CL9 latency limit throughput on a 1333MHz bus under sustained load?

The module runs at 1333MHz with CL9 timing and registered buffering, which adds one cycle of address/command delay but keeps throughput steady on a PC3-10600 bus.

How much heat and power does a 1.5V registered DIMM produce when running continuously?

At 1.5V standard DDR3 voltage the 4GB RDIMM draws typical DDR3 power and generates moderate heat; registered buffering adds minimal extra dissipation.

What motherboard slot and chipset support are required for this 240-pin DDR3 RDIMM?

A 240-pin DDR3 DIMM slot with registered ECC support in the chipset is required; the module uses major-brand chips at 1.5V.
