Compatible Supermicro DDR3 Kit

This 16GB kit contains two 8GB DDR3 ECC unregistered DIMMs validated for Supermicro X10SLL-F, X10SLL+-F and X10SLH-F motherboards. It targets administrators upgrading or repairing those specific platforms with guaranteed compatibility. Builders using other boards or requiring registered modules should look elsewhere.

240-Pin Unbuffered Build

Each module uses a standard 240-pin DDR3 interface and operates at 1.5V without a heat spreader unless current inventory includes one. The unbuffered design connects directly to the memory controller, so signal integrity depends on the board layout of the supported Supermicro models. Mixing with registered DIMMs is not supported on these platforms.

CL11 DDR3-1600 Thermals

Rated at DDR3-1600 with CL11 11-11-11 timings, the kit draws 1.5V under normal load. Without a guaranteed spreader, airflow across the sticks relies on the chassis and CPU cooler. ECC operation adds minimal overhead while providing error correction for data integrity in server workloads.

Questions about this item

What speed does the DDR3 1600 (PC3 12800) interface cap at in practice?

The modules run at 1600 MHz with a PC3 12800 data rate, limited by the Supermicro motherboard's memory controller.

What physical slot and clearance do these 240-pin DIMMs need to fit?

They require four 240-pin DDR3 DIMM sockets; each stick is a standard-height unregistered DIMM with no extra heat spreader unless inventory changes.

How are the two 8 GB sticks installed, and what step do builders often miss?

Populate the motherboard's four slots in the recommended channel order, then enable ECC in the BIOS so the error-correction feature actually activates.
