Supermicro Certified Server Memory

This 16 GB DDR3 1866 MHz registered ECC module is built for Supermicro platforms that require validated memory. It targets administrators upgrading or repairing compatible servers and workstations where error-correcting registered DIMMs are mandatory for stable operation.

Registered ECC 240-Pin RDIMM

The 240-pin RDIMM form factor fits DDR3 server slots that accept registered modules. The dual-rank 2Rx4 organisation and CL13 latency at 1.50 V allow the memory controller to manage signal integrity across populated channels without adding unbuffered load to the platform.

16 GB PC3-14900 Capacity Headroom

A single 16 GB stick raises total memory in supported configurations, improving multi-tasking and virtual-machine density. The module reaches its limit when the platform's maximum DIMM count or total memory ceiling is met, requiring additional slots or higher-density parts to scale further.

Questions about this item

Does the CL13 CAS latency become the bottleneck during long compute runs?

CL13 is the rated timing at 1866 MHz; sustained workloads will see the same latency unless the system downclocks the module.

How much heat does the 1.5 V registered DIMM produce in a fully populated server running 24/7?

Registered DDR3 at 1.5 V typically draws a few watts per module; total heat scales with the number of populated slots.

What motherboard feature must already be present for this ECC RDIMM to function?

The board must support DDR3 ECC registered memory and provide 240-pin RDIMM slots.
