A-Tech 4GB DDR3 1866 ECC UDIMM

This A-Tech module provides 4GB of DDR3 1866 server memory with ECC error correction for data integrity. It is built for servers and workstations that require unbuffered DIMMs running at standard 1.5V. The single-rank 1Rx8 design fits systems qualified for PC3-14900 CL13 specifications.

Thermals noise and power draw

Operating at the standard DDR3 voltage of 1.5V, the module draws typical power for its class without needing active cooling. Passive airflow in a server chassis is sufficient to maintain stable temperatures under normal workloads. The unbuffered design adds no extra electrical load on the memory controller.

Build quality connectors and mounting

The 240-pin DIMM form factor installs directly into standard DDR3 UDIMM slots on compatible server and workstation boards. Major-brand chips are used throughout and every unit undergoes quality-assurance testing for reliability. Buyers needing higher capacities or registered DIMM support should verify their platform requirements before ordering.

Vragen over dit artikel

How do I install the 240-pin DDR3 ECC UDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that ECC is enabled and the speed reads 1866 MHz.

What maintenance or replacement will this 4GB DDR3 module need over time?

No routine maintenance is required; keep air vents clear so the 1.5V modules stay cool, and replace only if memory diagnostics report uncorrectable ECC errors or the system fails to POST.

What limit appears first when this CL13 1866 MHz kit runs under sustained load?

The CAS latency of 13 cycles at 1866 MHz sets the timing floor; under heavy sustained workloads the memory controller hits that latency ceiling before thermal throttling becomes a factor.
