Server memory upgrade

This single 16GB DDR3 ECC registered RDIMM is built for Supermicro SuperServer 6036T 6046T 7046A 7046GT and 7046T systems. It adds capacity to workstations servers or NAS appliances that require registered error-correcting modules. The part will not work in standard desktop computers.

Thermal and power profile

Operating at 1.5V the module follows JEDEC DDR3 specifications and runs without a heat spreader. Registered buffering reduces electrical load on the memory controller which helps keep power draw predictable in multi-DIMM configurations. No active cooling is required for normal server operation.

Compatibility gate

The 240-pin DDR3 1333 CL9 2Rx4 form factor fits only platforms that accept ECC registered memory. Builders needing unbuffered DIMMs or a different DDR generation must choose another part.

Questions about this item

How do I install this 240-pin DDR3 ECC Registered RDIMM in a Supermicro SuperServer 6036T, and what is the common mistake?

Power down the server, open the chassis, align the module notch with the slot key, and press firmly until both retention clips click. The common mistake is mixing this registered ECC DIMM with unbuffered memory, which the system will not support.

What maintenance or replacement will this 16GB 2Rx4 module need over its service life?

No routine maintenance is required; the module has no heat spreader and no moving parts. If a memory error appears, run the server diagnostics to isolate the faulty DIMM and replace only that module.

What is the first limit reached under sustained load with this CL9 1.5V DDR3 1333 kit?

The memory controller’s maximum supported capacity per channel is reached before bandwidth or thermal limits become an issue.
