System-specific ECC upgrade

This OWC kit supplies 16 GB of DDR3L ECC registered memory in two 8 GB modules. It is built for Supermicro H8QGL, H8SCM, X10DBT, X10QBi and X10QBL series motherboards used in workstations and servers. The modules will not work in standard desktop computers.

DDR3L 1600 registered limits

The memory runs at 1600 MHz with CL11 latency at 1.35 V. Registered DIMMs require a motherboard chipset and BIOS that support buffered operation; they cannot be mixed with unbuffered modules. Capacity per slot is fixed at 8 GB with this kit.

240-pin RDIMM practicalities

Each module uses a standard 240-pin DDR3 DIMM form factor without a heat spreader, fitting typical server DIMM slots. The low-profile height aids airflow in dense chassis. Installation follows normal DIMM alignment; no extra cables or brackets are needed.

Questions about this item

Should I buy the 16 GB kit or look for a larger capacity?

This kit provides 16 GB as two 8 GB modules; if your Supermicro board has free 240-pin slots you can add more identical kits up to the board's maximum.

What does the 1600 speed rating deliver in a running server?

The modules run at DDR3L 1600 with CL11 timing, giving the bandwidth and latency the X10 or H8 series memory controllers are designed for.

Does the PC3L-12800 label limit the memory controller in any way?

PC3L-12800 is the JEDEC standard name for DDR3L 1600; the registered ECC design lets the motherboard's controller drive each DIMM at that rated speed.
