Server-Ready ECC Registered Kit

This 8 GB kit contains two 4 GB DDR3 modules built for registered ECC server platforms. Each stick uses a 240-pin DIMM form factor and runs at 1333 MHz with CL9 timing. The memory is validated for PC3-10600 registered operation and carries a lifetime warranty from the manufacturer.

Registered DIMM Build Requirements

Registered ECC modules require a motherboard and chipset that support registered signalling and ECC correction; they will not function in standard desktop boards. The kit frees non-ECC slots for other uses but demands a server-class memory controller to initialise correctly. No heat spreader is fitted, so airflow in the chassis must handle the bare DRAM.

8 GB Capacity For Light Workloads

Two ranks of 2Rx4 chips deliver 8 GB total, suitable for entry virtualisation hosts, file servers or test environments. The 1.5 V operation keeps power draw modest while the CL9 latency provides predictable access times. Workloads needing larger datasets or higher bandwidth will exceed this capacity and require additional DIMM slots or higher-density modules.

Questions about this item

Will the 1.5 V DDR3-1333 registered DIMMs throttle under sustained server workloads?

Registered ECC modules at CL9 9-9-9 timing run at the rated 1333 MHz without downclocking as long as the server’s memory controller supports PC3-10600.

How much heat and power do the 2Rx4 sticks generate during 24/7 operation?

Standard 1.5 V DDR3 registered DIMMs draw nominal power for the density; no heat spreader is fitted, so airflow across the 240-pin slots handles cooling.

Which server platforms accept this 240-pin ECC registered kit?

Any server mainboard qualified for PC3-10600R ECC registered DDR3-1333 memory; the kit is not compatible with desktop boards.
