Server-grade DDR3L ECC RDIMM

This OWC module delivers 8 GB of DDR3L 1600 memory with ECC and registered buffering. It operates at 1.35 V and carries CL11 latency in a 240-pin 1Rx4 form factor. The stick is validated for Supermicro H8QGL, H8SCM, X10DBT, X10QBi and X10QBL motherboard series.

Workstation and server upgrades only

The registered ECC design suits rack-mount servers, workstations and NAS appliances that require error correction and signal buffering. It will not function in standard desktop boards or consumer laptops, and it cannot be mixed with unbuffered DIMMs. Buyers needing non-ECC memory for a home PC should look elsewhere.

Registered ECC buffering decides fit

The single specification that determines compatibility is the registered ECC architecture. Only systems explicitly qualified for DDR3L registered ECC RDIMMs can use this module; any platform limited to unbuffered or non-ECC memory will reject it.

Questions about this item

Will this 240-pin DDR3L RDIMM fit in my Supermicro X10DBT motherboard?

Yes, the module is listed as compatible with Supermicro X10DBT series boards that accept 240-pin DDR3L ECC Registered memory.

Do I need to install these modules in specific slots on a dual-CPU Supermicro H8QGL board?

On dual-socket boards, populate the DIMM slots belonging to each CPU evenly; the common mistake is filling all slots on one processor while leaving the other empty.

How can I tell when this ECC Registered module should be replaced?

Watch for corrected ECC error counts climbing in the BMC or OS logs; a rising trend signals the DIMM is degrading and should be swapped.
