Server Memory Upgrade

This 32GB DDR4 module is built as a compatible replacement for Cisco UCS-ML-1X324RV-A and part number 15-104064-01. It targets administrators who need to expand capacity in supported server or workstation platforms. The load-reduced DIMM design helps maintain signal integrity on heavily populated memory channels. Systems that do not accept ECC LRDIMM 4Rx4 modules cannot use this product.

Thermals and Power

The module operates at the standard DDR4 voltage of 1.20V, which helps limit heat output during normal operation. As a registered load-reduced design, the onboard register reduces electrical loading on the memory bus without adding active cooling requirements. Typical server airflow is sufficient to keep temperatures within specification. No additional power draw beyond the rated voltage is expected under standard workloads.

Sustained Load Behaviour

Under continuous demand the ECC circuitry detects and corrects single-bit errors to preserve data integrity. The 4Rx4 organisation allows higher density per channel while the load-reduced buffer maintains stable signalling during extended sessions. CL17 latency at 2400MHz provides consistent timing for throughput-oriented tasks. Compatibility must be verified against the system qualified vendor list before deployment.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM in a Cisco UCS server and what step is often missed?

Align the notch on the module with the key in the 288-pin slot, press firmly until both ejector clips click shut, then verify in BIOS that the 32 GB module registers at 2400 MHz with ECC enabled.

What maintenance or replacement will this 32 GB ECC LRDIMM need over its service life?

No scheduled maintenance is required; the module is tested for lifetime reliability, and replacement is only necessary if a memory diagnostic reports uncorrectable ECC errors.

What limit appears first when this 4Rx4 1.20 V module runs sustained workloads?

The four-rank 4Rx4 organisation increases electrical loading, so the memory controller typically reaches its maximum supported rank-per-channel limit before bandwidth or thermal limits become an issue.
