8GB DDR3 1066 ECC RDIMM

This 8GB DDR3 1066 ECC RDIMM provides registered server memory for systems that require error correction and signal buffering. It suits administrators upgrading compatible Kingston part numbers such as KTM-SX310Q8/8G or KVR1066D3Q8R7S/8G. The module operates at 1.50V with a CL3 latency rating. Buyers needing unbuffered UDIMMs or higher-speed DDR3 cannot use this module.

Sustained load behaviour

Registered buffering and ECC circuitry maintain data integrity during continuous multi-threaded workloads typical of virtualisation hosts or database servers. The 4Rx8 organisation distributes access across four ranks, helping the memory controller manage sustained bandwidth demands. CL3 timing at 1066 MHz delivers predictable latency under extended operation. Modules are tested for reliability before shipment.

Installation and common issues

The 240-pin DIMM installs in standard DDR3 registered slots; verify that the platform supports 4Rx8 registered modules and 1.50V operation before purchase. A frequent issue is mixing registered and unbuffered DIMMs, which prevents boot. Another is exceeding the system's maximum rank count per channel, causing the module to be ignored. Confirm the qualified vendor list for your server model.

Questions about this item

How much heat does the 1.50 V DDR3 1066 module add when the server runs continuously?

At the standard 1.50 V DDR3 voltage the 8 GB RDIMM draws modest power, so a normal server airflow keeps temperatures in check during all-day workloads.

What must my motherboard provide to run this 240-pin registered ECC DIMM?

A DDR3 slot wired for registered ECC memory and a BIOS that accepts 4Rx8 modules at 1066 MHz.

Can I mix this 4Rx8 stick with older 2Rx8 DDR3 1066 DIMMs in the same channel?

Mixing ranks is possible only if the platform's memory controller supports asymmetric rank populations; otherwise the system will default to the lowest common speed or fail to post.
