  • 5V standard voltage fits DDR3 server platforms

Capacity & Form Factor

This is an 8GB DDR3 registered DIMM built to the PC3-8500 standard at 1066MHz with CL3 latency. It uses a 240-pin form factor and operates at the standard 1.50V for DDR3 server modules.

Suitable Systems & Limitations

It suits administrators upgrading or repairing servers that specifically require DDR3 ECC registered memory in a 4Rx8 configuration. Builders working with platforms that only accept unbuffered UDIMMs or newer DDR generations cannot use this module.

Deciding Specification

The registered ECC design with a 4Rx8 organisation is the critical attribute; the motherboard memory controller must explicitly support registered modules and this rank structure for the DIMM to function.

Questions about this item

How much power does this 1.50V DDR3 RDIMM draw when the server runs all day?

The module operates at the standard 1.50V DDR3 voltage; actual power draw depends on the server's memory controller and workload.

My system needs 240-pin DDR3 registered ECC — does this 4Rx8 module fit that slot?

Yes, it is a 240-pin DDR3 RDIMM with ECC and a 4Rx8 organisation, matching that requirement.

Will this Samsung-compatible 1066MHz stick work alongside my existing PC3-8500 CL3 modules?

It runs at DDR3 1066 (PC3-8500) with CL3 timing, so it can operate with identical-spec modules if the platform supports mixed ranks.
