8 GB DDR3 ECC RDIMM for servers

This 8 GB registered DIMM runs at DDR3 1600 with CL11 latency and 1.5 V standard voltage. It targets administrators upgrading or repairing DDR3-era servers and workstations that require ECC registered memory. The single-module format suits slot-limited boards or incremental capacity increases.

240-pin registered design with major-brand chips

The 240-pin DIMM uses a registered buffer to reduce electrical load on the memory controller, a requirement for many multi-socket platforms. Major-brand DRAM chips are specified, and each module undergoes quality-assurance testing before shipment. The 2Rx4 organisation fits systems expecting dual-rank x4 devices.

Direct replacement for three Hynix part numbers

This module matches Hynix HMT31GR7BFR4C-PB, HMT31GR7CFR4C-PB and HMT31GR7EFR4C-PB, simplifying sourcing when those original parts are unavailable. No additional accessories or software are bundled; the value lies in verified compatibility and the supplier's lifetime warranty with US-based technical support.

Questions about this item

What speed does the DDR3 1600 interface cap at in practice?

The module runs at DDR3 1600 MHz, rated PC3-12800, with CL11 latency and 1.50 V standard voltage.

What physical slot and dimensions does the 240-pin DIMM need to fit?

It uses a standard 240-pin DDR3 DIMM form factor, keyed for registered server boards that accept RDIMM modules.

How is the registered ECC RDIMM installed, and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, and verify the system detects ECC registered mode in BIOS.
