Server-Specific ECC Registered DIMM

This 64GB DDR4 module is built for the PowerEdge XE8545. It uses a 288-pin registered design with ECC for data integrity in server and workstation workloads. The part number is 3R2D42R464GB. It will not work in standard desktop computers or alongside unbuffered or load-reduced memory.

Low-Voltage JEDEC Operation

The module runs at 1.2V and conforms to JEDEC DDR4 3200 PC4-25600 specifications. Registered buffering and ECC logic add minimal overhead while maintaining signal stability under sustained load. No heat spreader is fitted, relying on chassis airflow for cooling in dense configurations.

Single-Module 64GB Capacity

One DIMM delivers 64GB in a 2Rx4 organisation at CL22 latency. Matching capacity, speed and manufacturer across all slots is recommended for optimal performance. Buyers needing smaller increments or non-ECC memory for desktop platforms should look elsewhere.

Questions sur cet article

How do I install this 288-pin DDR4 RDIMM in my PowerEdge XE8545, and what step do people often miss?

Power down the server, open the chassis, locate the DIMM slots, align the 288-pin module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all 64GB is detected at 3200 MT/s; the step often missed is confirming the memory mode matches registered ECC requirements.

What maintenance or replacement will this ECC registered module need over its service life?

No routine maintenance is required; if a correctable error count rises or the module fails POST, replace it with an identical 64GB 2Rx4 CL22 1.2V registered DIMM to keep rank and timing consistent across channels.

What limit appears first when this memory runs sustained workloads in the XE8545?

The DDR4 3200 PC4-25600 CL22 timing and 1.2V voltage set the bandwidth and latency ceiling; sustained heavy traffic will hit the JEDEC-rated throughput limit before thermal throttling becomes a factor.
