Server ECC RDIMM Kit

This 16GB kit contains two 8GB DDR3 1333 registered DIMMs built for Dell PowerEdge servers including the C2100, C6105, M910, R810 and R910. ECC and registered operation provide the error correction and signal integrity required by multi-socket workstation and server platforms. It will not work in standard desktop computers or alongside unbuffered modules.

Thermals and Power

Each module runs at the JEDEC standard 1.5V with no heat spreader, relying on the server chassis airflow for cooling. CL9 latency at PC3-10600 speed delivers the bandwidth these platforms expect without increasing power draw beyond the DDR3 specification. Registered buffering reduces electrical load on the memory controller, helping keep system power stable under full population.

Build and Compatibility

The 240-pin RDIMM form factor fits the target Dell PowerEdge slots directly, replacing Dell part numbers such as A2984886, A3198153, A3721483 and SNPX3R5MC/8G. 2Rx4 organisation matches the density requirements of the listed systems. JEDEC and RoHS compliance ensure a warranty-safe upgrade for extending older infrastructure or building cost-effective replacement servers.

Questions about this item

How do I install the 240-pin DDR3 ECC RDIMM modules in a Dell PowerEdge R810, and which step is often missed?

Power down the server, open the chassis, align each 240-pin module with the DDR3 slot key notch, press firmly until both retention clips click, then verify in BIOS that all 16GB are recognised at 1333MHz; the step often missed is ensuring the registered ECC modules are seated in the correct channel order for the R810 memory configuration.

What maintenance or replacement will the 1.5V DDR3 1333 CL9 2Rx4 kit need over its service life?

No routine maintenance is required for the DDR3 RDIMM modules; replacement is only needed if a module fails, which would be indicated by ECC corrected-error counts rising in the server management log or the system failing to POST with the 16GB kit installed.

What limit appears first when the 2Rx4 ECC registered memory runs sustained workloads on a PowerEdge R910?

The DDR3 1333 PC3-10600 bandwidth ceiling is the first limit under sustained use; the 1.5V 2Rx4 modules operate at their rated 1333MHz CL9 speed, so throughput caps at the PC3-10600 data rate before thermal or voltage constraints become factors.
