Cisco UCS M2814 specific upgrade

This 32 GB kit is built for the Cisco UCS M2814 Compute Cartridge. It contains two 16 GB DDR4 2133 registered ECC modules. The memory is designed for server and workstation platforms that require error correction and registered signalling. It will not work in standard desktop computers or with unbuffered or load-reduced DIMMs.

288-pin registered DIMM layout

Each module uses a 288-pin DDR4 RDIMM form factor without a heat spreader. The 2Rx4 organisation and 1.2 V operating voltage follow the PC4-17000 specification. Registered buffering adds a clock cycle to the command path, which is required by the target platform. Mixing these sticks with unbuffered or LRDIMM memory is not supported.

DDR4 2133 CL15 platform limits

The kit runs at 2133 MT/s with a CAS latency of 15, matching the JEDEC PC4-17000 standard. Registered ECC memory of this speed is tied to the memory controller of the Cisco UCS M2814 cartridge. Systems that do not support registered ECC DDR4 at this data rate cannot use the upgrade. Capacity is fixed at 32 GB across the two modules.

Questions about this item

Does DDR4 2133 PC4-17000 CL15 run at 2133 MHz in the Cisco UCS M2814 Compute Cartridge?

The kit is rated DDR4 2133 PC4-17000 CL15 and will operate at that speed when installed in the compatible Cisco UCS M2814 Compute Cartridge.

What physical slot and module dimensions are required for these 288-pin ECC Registered RDIMMs?

Each module uses the standard 288-pin DDR4 RDIMM form factor and fits the Cisco UCS M2814 Compute Cartridge memory slots designed for registered DIMMs.

How do I install the two 16 GB modules correctly, and what is the common mistake to avoid?

Power down the cartridge, open the chassis, align each 288-pin RDIMM with the slot key, press firmly until both latches click, then verify both modules are seated evenly; the frequent error is inserting only one module or leaving a latch unlatched.
