16 GB DDR3 1600 ECC Registered DIMM

This 16 GB DDR3 1600 module uses a 240-pin DIMM form factor and operates at 1.35 V. It includes ECC and registered signal processing for data integrity in server environments. The PC3 12800 rating confirms the 1600 MHz speed class. It suits administrators upgrading or repairing compatible DDR3 server platforms.

Steady throughput with registered buffering

The registered buffer reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time, preventing data corruption over long workloads. Lower 1.35 V voltage reduces power draw and heat compared to standard 1.5 V DDR3. These traits help maintain stability in 24/7 server deployments.

Verify DDR3 slot count and registered support

Confirm the motherboard accepts 240-pin DDR3 DIMMs and supports registered ECC modules. Some consumer boards only accept unbuffered memory and will not post with this stick. Check the system’s maximum per-slot capacity and total memory limit before ordering. Ensure the platform runs DDR3 at 1600 MHz or will downclock automatically.

Questions about this item

Does the 1.35 V DDR3 1600 registered DIMM run cooler than standard 1.5 V modules under continuous load?

The module operates at 1.35 V instead of the usual 1.5 V for DDR3, so it draws less power and produces less heat during all-day server workloads.

Must the motherboard have 240-pin DDR3 slots that support registered ECC memory?

Yes, the module is a 240-pin DDR3 registered ECC DIMM and requires a server board with registered ECC support; standard desktop boards will not accept it.

Can this 16 GB DDR3 1600 registered DIMM be mixed with existing DDR3 registered ECC modules of a different capacity?

Mixing is possible if the other modules are also DDR3 registered ECC; the system will run all sticks at the lowest common speed and timing.
