  • 288-pin DIMM form factor fits standard server slots

Server memory module

This is a 32GB DDR4 2133 ECC LRDIMM built as a compatible replacement for Cisco part numbers 15-102217-01 and UCS-ML-1X324RU-A. It runs at PC4-17000 speed with CL15 latency and 1.20V voltage. The module uses a 288-pin DIMM form factor and a 4Rx4 rank configuration with Major Brand Chipset components.

Suited for Cisco UCS upgrades

The module targets administrators expanding memory in Cisco UCS servers that specify these exact part numbers. Systems requiring standard RDIMM or non-ECC UDIMM modules cannot use this Load Reduced design. Buyers needing capacities beyond 32GB per slot or speeds higher than 2133MHz must select different modules.

Sustained load behaviour

ECC circuitry corrects single-bit errors continuously during prolonged workloads, preventing data corruption in virtualisation and database tasks. The Load Reduced buffer reduces electrical loading on the memory controller, helping maintain signal integrity across all ranks during extended operation. Quality assurance testing validates stability under continuous server duty cycles.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit the memory slots on my Cisco UCS server that uses the 15-102217-01 part number?

Yes, the module is built as a 288-pin DDR4 LRDIMM to match the physical slot and electrical interface of Cisco systems that specify the 15-102217-01 or UCS-ML-1X324RU-A part numbers.

Can I mix this 4Rx4 load-reduced module with standard registered DIMMs already installed in the same server?

No, load-reduced and standard registered DIMMs use different electrical signalling; they cannot be mixed in the same memory channel or, on most platforms, in the same system.

After installation, how can I confirm the module is running at DDR4 2133 with ECC active?

Check the BIOS memory information screen or use a tool such as dmidecode; it should report 2133 MT/s, PC4-17000, CL15 latency, 1.2 V and ECC type Load Reduced for the new 32 GB module.
