ECC registered DDR4 kit delivers 128GB across four 32GB modules at 3200 CL22 for Cisco UCS C4200 servers
Capacity 128GB (4 x 32GB)
This 128GB kit contains four 32GB DDR4 3200 CL22 registered ECC RDIMMs built for the Cisco UCS C4200 server. Each module runs at 1.2V with a 2Rx4 organisation and 288-pin form factor. It replaces Cisco part numbers 15-107238-01, UCSMRX32G2RW and UCSXMRX32G2RW. The kit is not compatible with standard desktop computers or with unbuffered and load-reduced ECC memory.
Installation follows the standard 288-pin DIMM procedure for the Cisco UCS C4200 chassis. All four slots must be populated with identical modules to maintain correct rank interleaving and ECC integrity. Mixing these registered DIMMs with unbuffered or load-reduced memory will prevent the system from booting. The supplier tests every module in-house before shipping to reduce the chance of a dead-on-arrival stick.
Registered ECC construction corrects single-bit errors on the fly during continuous operation, protecting data integrity in multi-user and virtualised environments. CL22 latency at 3200 MT/s delivers steady throughput for database and compute tasks that run for hours rather than minutes. The 1.2V operating voltage keeps power draw predictable across the fully populated memory subsystem.
