Supermicro 16GB DDR3 ECC Registered DIMM

This 16GB DDR3 module runs at 1600 MT/s with CL11 timing and a low 1.35V voltage. It uses a 240-pin form factor and carries a 2Rx4 registered ECC design. The part is built for Supermicro server platforms that require registered memory with error correction.

Servers needing registered ECC DDR3 at 1600 speed

The module suits systems that specify PC3-12800 registered DIMMs with ECC and a 1.35V operating voltage. It is not for platforms that require unbuffered non-ECC memory, different CAS latencies, or modules that exceed the stated speed and voltage ratings.

Registered ECC with 2Rx4 organisation

The single specification that determines fit is the registered ECC design combined with the 2Rx4 rank configuration. Only motherboards qualified for this exact organisation will initialise the module correctly.

Questions about this item

Does the 1.35 V DDR3 1600 module run cooler than standard voltage memory during continuous operation?

The 1.35 V rating lowers power draw compared to 1.5 V DDR3, which reduces heat output when the module runs all day in a server.

What motherboard slot and memory controller features are needed to use this registered ECC stick?

A 240-pin DDR3 slot with support for registered ECC memory is required; the memory controller must accept registered modules and ECC functionality.

Can this CL11 DDR3 1600 module share a channel with other DDR3 speeds?

Mixing speeds on the same channel forces all modules to run at the slowest speed and loosest timings present.
