Purpose-Built Server Memory

This 8GB DDR3 ECC Registered RDIMM is designed for Supermicro SuperWorkstation 7036A and 7046A series systems. It provides error-correcting, registered memory required for stable workstation and server operation. Standard desktop computers cannot use this module type.

Registered DIMM Build

The module uses a 240-pin DDR3 form factor with a 2Rx4 rank configuration and operates at 1.5V. Registered buffering reduces electrical load on the memory controller, allowing larger memory populations in compatible Supermicro platforms. No heat spreader is fitted.

DDR3 Platform Limits

DDR3 1333 speed and CL9 latency define the performance ceiling for this memory generation. Registered ECC modules cannot be mixed with unbuffered memory in the same system. Buyers needing higher bandwidth or newer memory standards must select a platform that supports later DDR generations.

Questions about this item

What speed does the DDR3 1333 (PC3-10600) interface actually run at in this Supermicro workstation?

The module operates at DDR3 1333 with PC3-10600 bandwidth and CL9 latency, matching the Supermicro SuperWorkstation 7036A and 7046A Series memory controller specification.

Will the 240-pin 1.5V ECC Registered RDIMM fit the DIMM slots on a Supermicro SuperWorkstation 7036A or 7046A?

Yes, the 240-pin DDR3 ECC Registered DIMM at 1.5V is the exact form factor and voltage required by the Supermicro SuperWorkstation 7036A and 7046A Series motherboards.

How do I install this 2Rx4 registered module, and what is the common mistake to avoid?

Power down the workstation, open the chassis, align the notch on the 240-pin DIMM with the slot key, press firmly until both retention clips lock, then verify the system recognises the full 8GB; the frequent error is mixing this registered ECC module with unbuffered memory, which prevents the system from booting.
