Dell Precision R5500 ECC upgrade

This kit provides 16 GB of DDR3 ECC registered memory in two 8 GB modules for the Dell Precision R5500 workstation. It is intended for servers and workstations that require error-correcting registered DIMMs and cannot accept standard unbuffered desktop memory.

Thermals noise and power draw

The modules operate at 1.5 V with a CL9 latency at 1333 MHz, matching the system's original specification. No heat spreaders are fitted, so airflow in the chassis determines operating temperature and the memory adds no audible noise.

Build quality and connectors

Each module uses a 240-pin 2Rx4 registered DIMM form factor that installs directly into the R5500 memory slots. The kit replaces a long list of Dell part numbers, confirming mechanical and electrical compatibility, but it will not work in systems that require unbuffered or non-ECC memory.

Questions about this item

How do I install the 240-pin DDR3 RDIMM modules in the Dell Precision R5500, and what step is commonly missed?

Power down the R5500, open the chassis, locate the DDR3 DIMM slots, align the notch on each 240-pin module with the slot key, press firmly until the retention clips lock, then verify in BIOS that both 8 GB modules are detected at 1333 MHz.

What maintenance or replacement will the ECC registered RDIMM kit need over time?

The modules have no heat spreader and no moving parts, so no routine maintenance is required; replacement is only necessary if a module fails or if the workstation is upgraded to a platform that does not support DDR3 ECC registered memory.

What limit appears first when the Dell Precision R5500 runs sustained workloads with this 16 GB DDR3 1333 CL9 kit?

The memory bandwidth ceiling of the DDR3 1333 interface is reached before capacity becomes a bottleneck, so sustained throughput tops out at the PC3-10600 data rate.
