8GB DDR3 ECC RDIMM for servers

This 8GB DDR3 1600MHz ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. The 2Rx4 organisation and CL11 latency suit multi-socket boards with registered memory controllers. It replaces several Samsung M392 and M393 part numbers in existing deployments.

Sustained workload behaviour

Registered buffering reduces electrical load on the memory bus, allowing stable operation when all slots are populated under continuous demand. ECC circuitry detects and corrects single-bit errors without halting the system. Standard 1.50V DDR3 voltage keeps power draw predictable during extended compute tasks.

240-pin DDR3 form factor decides fit

The module uses the 240-pin DDR3 DIMM keying, so it only fits slots wired for DDR3 registered memory. Boards that accept only unbuffered UDIMMs or a different DDR generation will not accept this part. Verify the platform manual lists RDIMM support before ordering.

Questions about this item

Will this 1.50V DDR3 1600MHz ECC RDIMM run hotter or louder than lower-voltage modules when operating continuously?

The module operates at standard DDR3 1.50V with CL11 latency. Registered ECC DIMMs add minimal electrical load, and thermal output is comparable to other 8GB DDR3 server sticks under sustained workloads.

Does my motherboard need to support registered ECC memory and 240-pin DDR3 DIMM slots to use this 8GB stick?

Yes. This is a 240-pin DDR3 ECC RDIMM (Registered) requiring a server or workstation board that explicitly supports registered ECC memory and DDR3 1600MHz operation.

Can I install this 2Rx4 PC3-12800 module alongside existing Samsung M393B1K70DH0-CK0 sticks in the same system?

This module is listed as a compatible equivalent for the Samsung M393B1K70DH0-CK0 and shares the same 2Rx4 organisation, 1600MHz speed, and 1.5V voltage, so it will interleave correctly when populated per the motherboard's memory-configuration rules.
