Cisco Server Memory Upgrade

This 16GB DDR3 1866 module is built for Cisco UCS B-Series B200 M3 servers. It delivers registered ECC reliability for mission-critical workloads. The single 16GB stick uses a 2Rx4 organisation and runs at 1.5V. It matches the Cisco UCS-MR-1X162RZ-A part number for direct replacement.

Sustained Load Behaviour

Registered buffering and ECC correction keep data integrity stable during continuous server operations. The CL13 latency supports consistent throughput under heavy multi-threaded demand. Samsung, Micron or Hynix chips provide enterprise-grade endurance. Modules are stress tested under load before shipping.

Compatibility Check

Verify your system requires 288-pin DDR3 RDIMMs and not 204-pin SODIMMs. Confirm the motherboard accepts 1.5V registered ECC modules at 1866MHz. Check available DIMM slots and maximum capacity per channel. Ensure the BIOS supports this density and rank configuration.

Questions about this item

How much power does the 1.5V DDR3 1866 module draw under continuous load?

The module operates at 1.35V, reducing power draw and heat compared to standard 1.5V DDR3 while running at 1866MHz all day.

What server slot and chipset are required to install this 288-pin ECC RDIMM?

It needs a DDR3 RDIMM slot with registered memory support, such as the Cisco UCS B200 M3 motherboard that accepts 2Rx4 modules.

Will this registered ECC stick work alongside older unbuffered DDR3 DIMMs in the same system?

No, registered and unbuffered DDR3 cannot be mixed; the motherboard requires all slots to use registered ECC modules like this 2Rx4 part.
