16GB DDR3L 1066 ECC RDIMM Server Module

This is a single 16GB DDR3L 1066 ECC Registered DIMM built for server and workstation platforms. It operates at 1.35V with CL7 latency and uses a 4Rx4 rank configuration on a 240-pin interface. The module is validated as a direct replacement for Samsung M393B2K70CM0-YF8 and equivalent part numbers. It targets administrators who need registered ECC memory to maintain data integrity in multi-slot configurations.

Suits registered ECC DDR3L 1066 systems only

This module fits servers that require DDR3L 1066 registered ECC DIMMs with 4Rx4 organisation and 1.35V operation. It will not work in desktops or laptops that accept only unbuffered non-ECC memory. It is also incompatible with platforms limited to DDR3 1.5V or higher voltage modules. Buyers needing unbuffered ECC or consumer SO-DIMM form factors should look at other products.

4Rx4 rank density decides motherboard slot support

The 4Rx4 organisation means each module presents four logical ranks to the memory controller. Many server boards limit the number of ranks per channel, so installing multiple 4Rx4 DIMMs can exceed that limit and prevent the system from posting. Verify the platform's maximum ranks per channel and qualified vendor list before purchasing.

Questions about this item

Will this DDR3L 1066 CL7 1.35V 4Rx4 RDIMM run reliably alongside existing DDR3L 1066 modules in my server?

Yes — matching speed, voltage, CAS latency, rank layout and registered ECC design lets it operate in the same channel without timing conflicts.

How can I confirm the module is detected at 1066 MHz with ECC active after installation?

Check the BIOS memory summary or run dmidecode / CPU-Z; they should show 1066 MHz, 1.35 V, ECC enabled and registered operation.

Does the package include only the single 240-pin DIMM or are any brackets or cables supplied?

Only the 16 GB 240-pin DDR3L RDIMM is included; no brackets, cables or additional hardware are provided.
