Dell PowerEdge 12th Gen upgrade kit

This 32 GB kit contains two 16 GB DDR3 1600 MHz ECC registered DIMMs built for Dell PowerEdge R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920 rack servers. The modules run at 1.5 V with CL11 latency and a 2Rx4 organisation, matching the 240-pin DDR3 slots used across the 12th Gen platform. IT teams handling virtualisation, database or compute workloads on these systems can add capacity without changing voltage or memory generation.

Replaces lower-capacity DDR3 RDIMMs

If the server currently runs 4 GB, 8 GB or 16 GB DDR3 1600 MHz registered modules, this kit doubles or quadruples the memory pool while keeping the same speed, voltage and ECC behaviour. The jump is worth it when workloads exceed the existing capacity and cause swapping or VM density limits, provided the CPU and chipset support the total amount installed. Systems already at the maximum supported capacity or running non-ECC unbuffered memory cannot use these modules.

Check DDR3 1600 MHz RDIMM support

Verify the server model appears in the compatible list and that the BIOS is current enough to recognise 16 GB dual-rank registered DIMMs. Confirm the memory-channel population rules for the specific CPU — some Xeon E5-1400, E5-2400, E5-2600, E5-4600, E7-2800, E7-4800 and E7-8800 series processors have per-channel rank limits. Ensure the operating system and hypervisor can address the additional memory. This kit will not fit desktop, laptop or non-ECC platforms.

Questions about this item

Will these 240-pin DDR3 modules fit the DIMM slots in a Dell PowerEdge R720?

Yes, the kit is built for Dell PowerEdge 12th Gen rack servers including the R720 and uses the standard 240-pin DDR3 form factor those systems require.

What is the correct way to install the two 16 GB sticks so the server recognises the full 32 GB?

Follow the server manual for channel population order; install identical modules in matched pairs per channel so the dual-rank 2Rx4 configuration registers correctly.

How long are the individual 16 GB modules covered against defects?

A-Tech backs every module with a lifetime warranty, so each 16 GB stick is protected for as long as you own it.
