Server memory upgrade

This 16 GB DDR3 module runs at 1066 MHz (PC3-8500) with CL7 latency and 1.50 V operation. It is a registered ECC DIMM built with major-brand chips in a 4Rx4 organisation. The 240-pin form factor fits server and workstation boards that require registered memory.

Sustained workload behaviour

Registered buffering and ECC correction keep data integrity stable during continuous multi-threaded tasks. The 4Rx4 rank layout allows the memory controller to interleave accesses across four ranks per channel. CL7 timing at 1066 MHz delivers consistent latency for database and virtualisation workloads.

Thermals and power draw

Standard 1.5 V DDR3 voltage limits per-module power consumption under typical server loads. Major-brand chips are tested to meet JEDEC thermal specifications without additional cooling. Registered operation adds negligible overhead compared with unbuffered modules.

Questions about this item

How much power does the 1.50 V DDR3 1066 module draw when the server runs continuously?

The module operates at the standard DDR3 voltage of 1.50 V; actual power draw depends on the server workload and the number of modules installed.

What motherboard slot and chipset support are required for this 240-pin 4Rx4 registered DIMM?

You need a server or workstation board with a 240-pin DDR3 slot that accepts registered ECC memory and supports 4Rx4 modules at PC3-8500 speed.

Can I mix this 16 GB PC3-8500 stick with older DDR3 1066 modules that have a different rank or voltage?

Mixing is possible only if the other modules are also 1.50 V registered ECC DDR3 1066; different ranks or voltages may prevent the system from booting.
