16 GB DDR3 ECC Registered DIMM

This 16 GB module uses 240-pin DDR3 SDRAM running at 1333 MHz (PC3-10600). It provides error-correcting code and registered signal processing for stable operation in compatible server platforms. The single DIMM format suits upgrades where registered memory is required.

ECC and registered buffering

Error checking corrects single-bit errors to protect data integrity in critical workloads. Registered signalling reduces electrical load on the memory controller, allowing larger memory populations in supported Intel S5520 and SuperMicro X8DTN+ or X9DAL-3 systems. These features change how the module interacts with the platform chipset.

Capacity and headroom for registered DDR3 servers

One 16 GB DIMM expands capacity in servers qualified for this speed and registration type, such as SuperMicro SuperServer 7046GT-TRF or SuperWorkstation 7047R-3RF4+. It runs out when the platform reaches its maximum DIMM count or total memory limit, which varies by motherboard model.

Questions about this item

Will the 240-pin DDR3 ECC registered DIMM require any periodic maintenance or replacement during normal server operation?

No scheduled maintenance is needed for the 16 GB DDR3-1333 registered ECC module; it is a solid-state component designed to remain in service for the life of the platform.

What limit appears first when the 16 GB DDR3-1333 registered ECC DIMM runs continuously at full load?

The memory controller's maximum bandwidth at 1333 MHz PC3-10600 is the first ceiling reached under sustained use.

How much heat and power does the 16 GB DDR3-1333 registered ECC DIMM produce when the server runs all day?

The DDR3-1333 registered ECC module operates at standard DDR3 voltage with low idle power; active power scales with access rate but stays within normal DIMM thermal limits.
