16GB Registered ECC Kit for PowerEdge R620

This 16GB kit contains four 4GB DDR3 1333 registered ECC DIMMs built for the Dell PowerEdge R620. Each module runs at 1.5V with CL9 timing and a 2Rx4 organisation. The 240-pin form factor matches the server's memory slots exactly.

Thermals, noise and power draw

Registered ECC modules operate at the standard 1.5V DDR3 voltage without a heat spreader, relying on the server's directed airflow for cooling. Power consumption stays within the platform's memory budget and the modules add no audible noise of their own.

Registered ECC requirement

The PowerEdge R620 accepts either registered ECC or unbuffered ECC memory but forbids mixing the two types within the same system. Buyers who need unbuffered ECC modules or who plan to combine registered and unbuffered sticks in one bank cannot use this kit.

Questions about this item

How do I install the four 4GB DDR3 1333 registered DIMMs in the Dell PowerEdge R620, and what step is often missed?

Populate each of the six banks with four identical modules; the common error is mixing the 313 x4 and 3138 x8 4GB registered ECC parts inside the same bank, which the system does not support.

What maintenance or replacement will the 16GB DDR3 1333 registered kit need later?

No scheduled maintenance is required; if a module fails, replace it with another 2Rx4 1.5V PC3-10600 registered ECC DIMM of the same rank and DRAM organisation to keep the bank uniform.

What limit appears first when the PowerEdge R620 runs sustained workloads with this 16GB DDR3 1333 registered memory?

The 1333 MHz DDR3 bus and CL9 latency set the bandwidth ceiling long before the 24-slot registered DIMM capacity limit of 384 GB or 512 GB is reached.
