Dell PowerEdge R420 memory kit

This 32 GB kit contains two 16 GB DDR3L registered ECC DIMMs validated for the Dell PowerEdge R420 server. Each module runs at 1333 MHz with CL9 timings at 1.35 V. The registered design adds a buffer that stabilises the memory bus in multi-DIMM configurations.

32 GB capacity and headroom

The R420 accepts up to 384 GB of registered ECC memory across twelve slots, so this kit occupies two slots and leaves ten free for future expansion. The system also supports unbuffered ECC up to 48 GB, but registered and unbuffered modules must not be mixed in the same memory bank.

Build integration details

These 240-pin DDR3L modules require a PowerEdge R420 motherboard with matching registered ECC support; they will not work in desktop boards or systems that only accept unbuffered memory. Installing like-ranked modules within each bank ensures proper operation and avoids mixing the x4 and x8 4 GB variants that the platform distinguishes.

Questions about this item

Will these two 16GB DDR3L 1333 registered ECC modules work alongside the 4GB registered ECC sticks already in my PowerEdge R420?

The R420 supports mixing 4GB and 16GB registered ECC modules across different memory banks, but x4 and x8 DRAM versions of the 4GB parts must not share the same bank.

How can I confirm the kit is running at the correct 1333 MHz speed and CL9 timing after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show 1333 MHz DDR3L at 1.35 V with 9-9-9 timings for each 16 GB module.

Does the package include only the two 16GB DIMMs or are heat spreaders and any extra cables supplied?

The box contains the two 240-pin DDR3L registered ECC DIMMs; heat spreaders are fitted only if current inventory requires them and no additional cables are included.
