8 GB DDR3 ECC RDIMM for legacy servers

This 8 GB DDR3 1066 module is built for registered server platforms that require ECC and 4Rx8 organisation. It operates at the standard 1.5 V DDR3 voltage with CL7 latency. The 240-pin DIMM fits systems validated against the listed IBM-Lenovo part numbers.

Registered buffer and ECC protect data integrity

The registered design reduces electrical load on the memory controller, allowing stable operation in multi-module configurations. ECC circuitry detects and corrects single-bit errors, preventing silent data corruption in workloads that cannot tolerate faults. Major-brand chips are tested before shipment to confirm reliable behaviour.

Single 8 GB module suits moderate capacity needs

One module adds 8 GB to a compatible channel, useful for expanding older virtualisation hosts or database nodes. The 4Rx8 rank structure limits the number of modules a channel can accept, so maximum system capacity depends on the platform’s rank limit. Buyers needing more than 8 GB per channel or non-ECC memory should verify their platform’s rules first.

Questions about this item

Will the registered ECC RDIMM design require any special handling or periodic replacement compared to standard memory?

The module is a standard DDR3 240-pin registered ECC RDIMM with major-brand chips; it installs like any server DIMM and has no user-serviceable parts or scheduled replacement interval.

What is the first bottleneck you hit when running this 8 GB 1066 MHz CL7 kit at full load for hours?

The 1066 MHz PC3-8500 data rate and CL7 latency set the throughput ceiling, so sustained bandwidth tops out at the rated DDR3 1066 speed.

How much heat and power does a single 1.5 V 4Rx8 stick produce in a 24/7 server?

At the standard 1.50 V DDR3 voltage the module draws nominal DDR3 power and runs at typical registered-DIMM temperatures; no extra cooling beyond normal server airflow is required.
