8 GB DDR3-1866 registered ECC module

This 8 GB DDR3-1866 registered ECC module is built for servers and workstations that require error-correcting memory. The 1Rx4 organisation and low-profile form factor suit dense multi-socket platforms. It operates at 1.50 V and carries Supermicro certification for qualified systems.

Sustained throughput with registered buffering

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors in real time, preventing data corruption under prolonged workloads. The DDR3-1866 speed rating delivers 14900 MT/s bandwidth for steady throughput in virtualisation and database tasks.

Verify DDR3 registered ECC support before ordering

Confirm the motherboard accepts 240-pin DDR3 registered ECC DIMMs at 1.50 V. Systems limited to unbuffered or non-ECC memory cannot use this module. Check the qualified vendor list for the 1Rx4 rank configuration and low-profile clearance.

Questions about this item

Will the 1.50 V DDR3-1866 registered modules run hotter or noisier than standard unbuffered DIMMs under continuous load?

Registered DIMMs add a register chip that draws a small amount of extra power, but the 1.50 V rating is the same as standard DDR3; any temperature rise is handled by the server's existing airflow and does not create audible noise.

What motherboard features are required to use this 240-pin DDR3 ECC registered memory?

The board must provide 240-pin DDR3 slots that support ECC and registered (buffered) operation; consumer desktop chipsets typically lack this support.

Can this 1Rx4 PC3-14900 module share a channel with older DDR3 registered DIMMs of a different rank?

Mixing ranks in the same channel is generally unsupported; the memory controller expects identical rank geometry per channel, so populate each channel with matching modules.
