Cisco UCS M2814 compatible memory kit

This 128GB kit contains four 32GB DDR4 ECC registered DIMMs built for the Cisco UCS M2814 Compute Cartridge. It is designed for servers and workstations that require registered memory with error correction. Standard desktop computers cannot use these modules.

Registered DDR4 2133 CL15 at 1.2V

Each module uses a 288-pin 2Rx4 organisation and runs at PC4-17000 speed with CAS latency 15. The registered buffer and ECC function demand a platform that supports registered DIMMs; they cannot be mixed with unbuffered or load-reduced memory. No heat spreader is fitted.

Replaces Cisco part numbers 15-103025-01

The kit substitutes original Cisco modules including UCSMR1X322RUARF, UCSMR1X322RUG, UCSSPLM32G and UCSSPMM32RUA. JEDEC and RoHS compliance ensures a warranty-safe upgrade for the target cartridge.

Questions about this item

Will the CL15 latency at DDR4 2133 speed become a bottleneck under sustained server workloads?

The kit runs at DDR4 2133 with CL15 timing, which is the standard JEDEC specification for this speed grade and matches the Cisco UCS M2814 compute cartridge requirements.

How much heat do four 32 GB registered DIMMs generate when the cartridge runs continuously?

Each module operates at 1.2 V without a heat spreader; registered ECC RDIMMs at this voltage typically stay within normal server thermal limits when installed in the Cisco UCS M2814 with its designed airflow.

Does the Cisco UCS M2814 compute cartridge need a specific BIOS version or CPU to recognise this 128 GB kit?

The kit is listed as a direct replacement for Cisco part numbers including 15-103025-01, UCSMR1X322RUA and UCSSPLM32G, indicating compatibility with the cartridge's supported configurations.
