8GB DDR3L ECC RDIMM for servers

This 8GB DDR3L 1333MHz ECC registered DIMM is built for servers and workstations that require error-correcting memory. It replaces the Samsung M392B1G70BH0-YH9 module with a compatible A-Tech alternative. The single-rank 1Rx4 design uses Samsung chipset components. It fits 240-pin DDR3 DIMM slots in supported enterprise platforms.

Low-voltage operation at 1.35V

Running at 1.35V, this DDR3L module draws less power and generates less heat than standard 1.5V DDR3 at the same 1333MHz speed. The registered buffer reduces electrical load on the memory controller, aiding stability in multi-DIMM configurations. CL9 latency delivers predictable timing for typical server workloads. No active cooling is required on the module itself.

Upgrade from smaller or non-ECC DDR3

This module suits administrators adding capacity to compatible DDR3L platforms or replacing failed 4GB or non-ECC sticks. The jump is worthwhile when ECC protection and registered signalling are mandatory for data integrity. It will not work in systems limited to unbuffered UDIMMs or those requiring 1.5V-only memory. Verify your platform's qualified vendor list before purchasing.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and what step is often missed?

Align the notch on the module with the key in the 240-pin slot, press firmly until both retention clips click, then verify in BIOS that the server registers the full 8GB at 1.35V — the step most often missed is confirming the registered ECC mode is enabled in firmware.

What maintenance or replacement will this 1Rx4 Samsung-chipset module need over time?

No routine maintenance is required; the module either passes POST or it does not, so replacement only occurs if a memory test reports uncorrectable ECC errors or the system fails to recognise the 8GB capacity.

What limit appears first when this CL9 1.35V RDIMM runs sustained workloads?

The 1333MHz bus speed and CL9 latency set the throughput ceiling; under continuous load the memory controller hits that bandwidth limit before the 1.35V low-voltage thermal envelope becomes a constraint.
