8 GB DDR3L 1066 ECC RDIMM for servers

This 8 GB DDR3L 1066 ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. The module runs at PC3L-8500 speed with a CAS latency of CL7 and operates at the low 1.35 V DDR3L voltage. It targets administrators upgrading or repairing compatible IBM-Lenovo systems.

240-pin registered DIMM with 4Rx8 organisation

The stick uses a standard 240-pin DIMM form factor and a 4Rx8 rank layout with major-brand chips. Registered buffering reduces electrical load on the memory controller, allowing larger memory populations in multi-socket boards. The pin-out matches the DDR3L keying so it only fits slots wired for 1.35 V operation.

Low-voltage DDR3L thermals and power

At 1.35 V the module draws less power and generates less heat than standard 1.5 V DDR3, helping chassis airflow in dense rack enclosures. ECC circuitry adds minimal overhead while correcting single-bit errors in real time. The registered design keeps signal integrity stable under sustained workloads without increasing acoustic noise.

Questions about this item

What DDR3L standard does this 8GB module use and what speed does it cap at?

It runs at DDR3L 1066 (PC3L-8500) with CL7 latency and 1.35V operation.

What physical slot does this 240-pin RDIMM need to fit in?

A DDR3 DIMM slot with 240 pins; the registered design requires a server or workstation motherboard that supports RDIMMs.

How is this ECC registered module installed and what step is often missed?

Power down, open the chassis, align the notch on the 240-pin edge connector, press firmly until both clips lock, then verify in BIOS that ECC and registered modes are enabled.
