Product identity

This Samsung M393B2G70DB0-YK0 module provides 16GB of DDR3 registered ECC memory running at 1600 MT/s with CL11 latency. It uses a 240-pin DIMM form factor and operates at 1.35V, making it suitable for compatible server and workstation platforms.

Target fit

It suits administrators upgrading or repairing systems that require registered dual-rank DDR3 ECC modules at this speed and voltage. Builders needing unbuffered memory, higher frequencies, different capacities, or later DDR generations should look elsewhere.

Build integration

The module plugs into a standard 240-pin DDR3 slot and relies on the platform's memory controller to support registered ECC operation at 1.35V. Its dual-rank organisation helps populate channels efficiently in multi-socket servers without adding extra physical slots.

Questions about this item

Does my motherboard need 240-pin DDR3 slots that accept registered ECC modules for this M393B2G70DB0-YK0 kit to work?

Yes, the module is a 240-pin DDR3 SDRAM with registered ECC, so the board must provide DDR3 slots that support registered error-correcting memory at 1.35 V.

Can I mix this CL11 1.35 V registered stick with older CL9 1.5 V unbuffered DDR3 DIMMs?

No, registered and unbuffered DIMMs cannot be used together, and the voltage mismatch would prevent stable operation.

How do I verify the module runs at DDR3 1600 CL11 with ECC active after installation?

Check the BIOS memory information or an OS tool such as dmidecode; it should report 1600 MT/s, CAS 11, 1.35 V and ECC enabled.
