16GB DDR3 1066 ECC Registered module

This 16GB Samsung DDR3 module runs at 1066 MT/s with a CAS latency of CL7 and operates at 1.35V. It uses a 240-pin form factor and features ECC registered technology with a 4Rx4 rank configuration. The module is designed for server environments requiring error correction and signal buffering.

Check motherboard DDR3 registered support

Verify that your server motherboard accepts 240-pin DDR3 registered DIMMs and supports 1.35V operation. The board must also handle 4Rx4 rank modules and the PC3-8500 speed grade. Systems limited to unbuffered memory or lower rank counts will not be compatible with this module.

Suits servers needing registered ECC capacity

This module fits administrators expanding memory in compatible DDR3 servers that require registered ECC DIMMs. It is not for desktop PCs or workstations that only accept unbuffered memory. Buyers needing higher speeds, different voltages, or non-ECC modules should look elsewhere.

Questions about this item

What comes in the box with the M393B2K70DM0-YF8 module, and do I need to buy any extra brackets or cables?

The box contains the single 16GB 240-pin DDR3 registered DIMM. No brackets, cables or additional parts are required for installation in a compatible server slot.

The specs show 4Rx4 rank and CL7 latency — which version should I pick if my server manual asks for dual-rank modules?

This module is a quad-rank 4Rx4 part; it does not meet a dual-rank requirement. Choose a different SKU if your platform specifically needs dual-rank memory.

The headline speed is DDR3 1066 (PC3 8500) — what does that mean for real-world throughput in my server?

The module runs at 1066 MT/s with a peak bandwidth of 8500 MB/s per channel, delivering ECC-protected registered performance at 1.35V for compatible DDR3 server platforms.
