16GB DDR3L Registered ECC Module

This 16GB DDR3L 1066MHz PC3-8500 ECC RDIMM provides registered error-correcting memory for server and workstation platforms. It operates at 1.35V low voltage using a 4Rx8 organisation across a 240-pin DIMM form factor. The module is a compatible replacement for the Kingston KTM-SX313QLV/16G part number.

Suits servers needing registered ECC DDR3L.

Systems that require registered ECC DDR3L memory at 1066MHz will accept this module directly. Builders using consumer desktop boards that only support unbuffered non-ECC DDR3 cannot use this stick. Buyers who need higher frequencies, different voltages, or unregistered DIMMs should look at other memory types.

Fits 240-pin DDR3 slots.

The DIMM installs into standard 240-pin DDR3 sockets that support registered ECC operation at 1.35V. Adding this 16GB module increases total system memory, allowing the server to handle larger datasets and more concurrent virtual machines without swapping to disk.

Questions about this item

Does my server motherboard need 240-pin DDR3L RDIMM slots to accept this module?

Yes, this is a 240-pin DDR3L ECC RDIMM that requires a server board with registered DIMM slots supporting 1.35 V operation.

Can I mix this 4Rx8 16 GB stick with my existing 2Rx4 DDR3L 1066 MHz modules?

Mixing ranks is possible if the motherboard qualifies the combined population, but 4Rx8 places a heavier load on the memory controller than 2Rx4.

How do I confirm the module runs at 1066 MHz CL3 with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode to verify speed 1066 MT/s, CAS 3, 1.35 V and ECC enabled.
