Supermicro Certified 4GB DDR3 Module

This 4GB DDR3 module carries Supermicro certification and uses Micron chips to deliver ECC registered operation at 1333MHz. It is built for servers and workstations that require error-correcting registered memory.

Fits 240-Pin RDIMM Slots at 1.5V

The stick plugs into a standard 240-pin RDIMM socket and runs at the DDR3 standard voltage of 1.5V. Its dual-rank 2Rx4 organisation lets the memory controller address more banks per channel without adding extra modules.

Low-Voltage DDR3 Operation

Running at 1.50V keeps power draw modest for DDR3, so the module adds little heat to a populated server chassis. ECC and registered buffering operate transparently, maintaining data integrity without audible noise.

Questions about this item

Will the 1.5V DDR3 voltage limit how many modules I can run continuously?

The module operates at the standard 1.5V DDR3 voltage, so sustained use is limited by your platform's maximum DIMM count and total power budget rather than the stick itself.

Does the registered ECC design add noticeable heat or fan noise during all-day workloads?

Registered ECC DIMMs run at the same 1.5V as standard DDR3 and do not require extra cooling; any heat or noise comes from the server chassis and CPU load, not the memory.

Must my motherboard support 2Rx4 registered ECC RDIMMs for this 240-pin kit to function?

Yes — the system must accept DDR3 1333 registered ECC RDIMMs in a 240-pin slot; consumer boards that only take unbuffered non-ECC UDIMMs will not work.
