8 GB DDR3L ECC RDIMM for Supermicro workstations

This 8 GB DDR3L 1600 CL11 module is a registered ECC DIMM built for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems. It operates at 1.35 V and uses a 240-pin form factor with a 1Rx4 organisation. The part replaces Supermicro MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16 modules.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing stable operation when all slots are populated in multi-socket servers. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The low 1.35 V DDR3L voltage limits heat output, helping the module maintain rated CL11 timing under continuous utilisation.

Compatibility constraint: registered ECC only

This module will not work in standard desktop motherboards or any platform that requires unbuffered non-ECC memory. It also cannot be mixed with unbuffered DIMMs in the same system. Buyers needing memory for consumer PCs or laptops must select a different product.

Questions about this item

How much power does the 1.35 V DDR3L module draw when the workstation runs continuously?

The module operates at 1.35 V, which is lower than standard DDR3 voltage, reducing overall power draw and heat output during all-day workloads.

What must the Supermicro SuperWorkstation already have for this 240-pin ECC RDIMM to function?

The system must support DDR3L 1600 registered ECC memory and provide a 240-pin DIMM slot; it cannot accept unbuffered modules.

Can this CL11 registered stick sit alongside older unbuffered DDR3 DIMMs in the same Supermicro chassis?

No, registered ECC memory cannot be mixed with unbuffered memory; all slots must use registered ECC modules for stable operation.
