Server Memory Kit

This 16GB kit contains four 4GB DDR3 ECC Registered DIMMs rated at 1333MHz with CL9 timing. It is built specifically for the Dell PowerEdge R520 server platform and runs at 1.5V. The modules use a 2Rx4 rank configuration with major brand components.

Registered ECC Design

Registered buffering and ECC error correction work together to maintain data integrity under continuous server workloads. The four-stick package fills four of the twelve total DIMM slots available across both processors. Mixing these registered modules with unbuffered ECC memory is not supported in this system.

For PowerEdge R520 Upgrades

This kit suits administrators expanding a Dell PowerEdge R520 with matched registered ECC modules. It is not for systems that require unbuffered ECC only, nor for builders needing higher-density 8GB or 16GB single modules to reach the 384GB registered maximum. Desktop or laptop users should look elsewhere.

Questions about this item

Will the 4GB 2Rx4 registered DIMMs need to be replaced if I expand beyond 16GB?

The PowerEdge R520 supports up to 384GB with registered ECC RDIMMs across 12 total sockets, so the 4x4GB kit can remain installed while you add more modules to reach higher capacities.

What limits sustained throughput on the 1333MHz DDR3 kit?

The PC3-10600 rating caps maximum bandwidth at 10600 MB/s; sustained workloads will hit that ceiling before the CL9 9-9-9 timings or 1.5V voltage become bottlenecks.

How much heat and power do the four registered sticks produce under all-day load?

Each 4GB 2Rx4 module runs at 1.5V; total power draw stays within standard DDR3 registered DIMM limits, and the kit ships with heat spreaders based on current inventory to manage thermals during continuous operation.
