Supermicro Certified 4GB DDR3 Module

This 4GB DDR3 1866 ECC registered DIMM carries Supermicro certification for direct replacement in qualified servers and workstations. The module runs at PC3-14900 speed with CL13 latency and standard 1.50V operation.

1Rx8 Registered ECC For Enterprise Platforms

Suits administrators expanding memory in systems that require registered ECC DDR3 on a 240-pin interface. Builders needing unbuffered non-ECC modules, higher capacities per stick, or newer DDR generations should look elsewhere.

Single Rank CL13 At PC3-14900

The 1Rx8 organisation at CL13 determines electrical loading and timing compatibility with the memory controller. Verify the platform's qualified vendor list for this exact speed, rank and voltage before ordering.

Questions about this item

Does this 240-pin RDIMM fit a standard DDR3 server DIMM slot?

Yes, the module uses the 240-pin RDIMM form factor and 1.5 V DDR3 standard voltage, so it fits any DDR3 registered DIMM slot keyed for that voltage.

What BIOS setting or installation step is commonly missed when adding this registered ECC module?

Enable ECC and registered memory support in the BIOS before booting; many users forget this and the system will not recognise the module.

When should the 4 GB DDR3 1866 CL13 module be replaced in a production server?

Replace it if memory diagnostics report correctable or uncorrectable ECC errors, or when a capacity upgrade requires higher-density DDR3 modules.
