Server Memory Upgrade

This 16GB DDR3L RDIMM operates at 1066MHz with CL7 latency and 1.35V low voltage. It uses a 4Rx4 registered ECC design on a 240-pin form factor. The module targets administrators upgrading compatible Dell PowerEdge servers or workstations that require registered error-correcting memory.

Build Integration

The registered buffer reduces electrical load on the memory controller, allowing higher-density configurations in supported platforms. ECC circuitry detects and corrects single-bit errors to protect data integrity. The 1.35V DDR3L specification lowers power draw compared to standard 1.5V DDR3. Verify your system accepts 4Rx4 registered modules before installation.

Capacity and Limits

A single 16GB module expands usable memory for virtualization, databases, or compute workloads. The 4Rx4 organisation may restrict maximum population rules on some motherboards, so consult the vendor documentation for slot limits. Systems capped at lower densities or requiring unbuffered DIMMs cannot use this module.

Questions about this item

Will the 4Rx4 registered DIMM run at its rated 1066 MHz in a Dell server that only supports PC3-8500?

Yes, the module is rated PC3L-8500 at 1066 MHz and the registered 4Rx4 design matches the Dell part numbers listed, so it will operate at that speed when the platform supports it.

How much heat and power should I expect from a 1.35 V DDR3L 16 GB RDIMM running continuously?

At 1.35 V the DDR3L module draws less power and generates less heat than standard 1.5 V DDR3, making it suitable for 24/7 server operation within normal chassis airflow.

Does my system need a 240-pin DDR3L ECC registered memory slot to use this module?

Yes, the module is a 240-pin DDR3L ECC RDIMM, so the motherboard must provide a DDR3L registered DIMM slot with ECC support for it to function.
