A-Tech 32GB DDR3 1600 ECC RDIMM Kit

This 32GB kit contains four 8GB registered DDR3 modules rated at 1600MHz with CL11 latency. It is built for Dell PowerEdge 12th generation rack servers including the R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920. The modules use a 2Rx4 organisation and run at 1.5V.

Verify ECC Registered DDR3 Support Before Ordering

This memory is ECC registered DDR3 and will not work in desktops or laptops that only accept non-ECC unbuffered modules. Confirm your server model appears in the supported list and check the manual for correct channel population rules. The kit is validated for Xeon E5-1400, E5-2400, E5-2600, E5-4600, E7-2800, E7-4800 and E7-8800 series processors.

Low-Profile Modules Run Cool in Dense Racks

The sticks have no heat spreader, relying on the server's directed airflow for cooling. Registered buffering reduces electrical load on the memory controller, helping keep power draw modest at 1.5V. In normal operation the modules stay within thermal limits without adding audible fan noise.

Questions about this item

Does the kit include only the four memory modules or any extra parts such as heat spreaders?

The package contains four 8 GB DDR3 1600 MHz ECC registered DIMMs and nothing else; no heat spreaders or additional accessories are included.

Should I pick this 32 GB (4 × 8 GB) 2Rx4 kit or a different capacity for my Dell PowerEdge R720?

This 32 GB kit matches the R720’s DDR3 1600 MHz registered ECC requirement and uses the 2Rx4 organisation the server expects; choose a different kit only if you need more or less total memory.

What does the 1600 MHz PC3‑12800 rating mean once the modules are installed in a PowerEdge R620?

The memory will run at 1600 MHz with CL11 latency at 1.5 V, delivering the rated PC3‑12800 bandwidth as long as the R620’s memory controller is configured for DDR3‑1600 registered ECC operation.
