Server DDR3 1600 ECC RDIMM

This NEMIX RAM module is a 16 GB DDR3 1600 registered DIMM with ECC and a 2Rx4 organisation. It operates at 1.20 V and uses the standard 240-pin form factor for server and workstation platforms. The part number is MR12800-624K1 and the chips are sourced from major OEM suppliers such as Samsung, Micron or Hynix.

NAS upgrades and registered-memory systems

The stick suits administrators expanding a QNAP NAS or any server that requires registered ECC DDR3 memory at 1600 MT/s. It will not work in desktop boards that only accept unbuffered non-ECC modules, nor in systems limited to lower densities or different voltages. Buyers needing unbuffered DIMMs or higher speeds must select a different product.

Check DDR3 RDIMM slot availability

Verify that your motherboard or NAS has a free 240-pin DDR3 slot that supports registered ECC modules at 1600 MT/s and 1.20 V. Confirm the maximum supported capacity per slot and the total population rules in the system manual before ordering. Ensure the platform accepts 2Rx4 rank configuration for stable operation.

Questions about this item

Do I need a server motherboard with 240-pin DDR3 RDIMM slots that support registered ECC memory?

Yes, this module is a 240-pin DDR3 RDIMM with ECC and registered buffering, so the motherboard must provide registered DDR3 slots that accept ECC memory.

Can I mix this 16 GB 1600 MHz CL11 1.20 V RDIMM with existing DDR3 RDIMMs of different speeds or ranks?

The system will run all modules at the lowest common speed and voltage; mixing ranks is possible but may limit maximum capacity per channel depending on the motherboard.

How can I confirm the module is running at 1600 MHz with ECC active after installation?

Check the BIOS memory information or use a system utility such as CPU-Z to verify the reported speed, CAS latency, voltage and ECC status.
