8GB ECC UDIMM for servers

This A-Tech module provides 8GB of DDR3 1866MHz memory with ECC error correction. It uses a 240-pin unbuffered DIMM form factor and runs at the standard 1.50V voltage. The stick is built as a direct replacement for Hynix HMT41GU7AFR8C-RD and HMT41GU7BFR8C-RD parts.

CL13 latency and 2Rx8 layout

The CAS latency is rated at CL13 and the chips are arranged in a dual-rank 2Rx8 configuration. These timings suit server and workstation boards that support DDR3 ECC UDIMMs at this speed. Systems requiring registered DIMMs or a different voltage will not be compatible.

PC3-14900 speed rating

The module operates at the PC3-14900 data rate, which is the single specification that confirms whether your platform can use this memory. Check your motherboard or system documentation for DDR3 1866MHz ECC UDIMM support before ordering.

Questions sur cet article

Will the 2Rx8 ECC chips need replacement under normal server workloads?

The module uses major-brand chips tested to A-Tech quality standards and carries a lifetime warranty, so no chip-level replacement is expected during its service life.

What limits sustained throughput on this DDR3-1866 CL13 stick?

The CL13 latency at 1866 MHz sets the timing ceiling, so sustained bandwidth tops out at the PC3-14900 rating.

How much heat and power does the 1.50 V unbuffered DIMM produce all day?

At standard 1.50 V DDR3 voltage the 8 GB UDIMM runs within normal thermal limits for 240-pin server slots, requiring only typical chassis airflow.
