Server memory kit

This OWC kit provides 64 GB of DDR3L ECC registered memory in four 16 GB modules. It is built for Supermicro H8QGL, H8SCM, X10DBT, X10QBi and X10QBL motherboards used in workstations and servers. The modules run at 1600 MHz with CL11 latency and 1.35 V operation. They will not work in standard desktop computers or alongside unbuffered DIMMs.

Sustained operation

ECC registered design corrects single-bit errors and reduces electrical load on the memory controller during continuous workloads. The 1.35 V DDR3L voltage lowers power draw compared with standard DDR3, helping stability in densely populated servers. No heat spreader is fitted, so chassis airflow must carry heat away from the modules during long runs.

Compatibility check

Verify that your motherboard model matches one of the listed Supermicro series and that all DIMM slots accept 240-pin registered DDR3L. The system BIOS must support 2Rx4 organisation and 64 GB total capacity across four slots. Do not mix these modules with unbuffered or non-ECC memory.

Questions about this item

How much power does the 1.35 V DDR3L kit draw when the server runs all day?

Each module operates at 1.35 V, the standard DDR3L voltage, so the four 16 GB sticks together consume less power than equivalent 1.5 V DDR3 kits under continuous load.

Which motherboard must I already own for this 240-pin registered ECC kit to work?

The kit is validated for Supermicro H8QGL, H8SCM, X10DBT, X10QBi and X10QBL series motherboards that support 240-pin DDR3L registered ECC DIMMs.

Can I keep my existing unbuffered DDR3 DIMMs and add this 2Rx4 registered kit alongside them?

No — registered ECC modules cannot be mixed with unbuffered memory; all slots must use registered ECC DIMMs for the system to function correctly.
