AddOn AA783422-AM 32GB DDR4-3200MHz CL17 RDIMM server RAM

SKU CH-JRRB-H8XV7 MPN AA783422-AM

32 GB DDR4 RDIMM with ECC, registered dual-rank design, CL17 latency at 3200 MHz and 1.2 V operation

  • Capacity32GB
  • 32 GB capacity supports large workloads
  • DDR4-3200 MHz speed moves data quickly
  • CL17 latency keeps response tight
  • ECC registered design protects data integrity
  • Dell AA783422 compatible for direct replacement

Dell-compatible 32GB DDR4 RDIMM

This 32GB DDR4-3200MHz registered ECC module is built for Dell servers that require the AA783422 part number. It suits administrators upgrading memory capacity in supported platforms without mixing unregistered DIMMs. Buyers needing non-ECC or unbuffered memory for workstation boards should look elsewhere.

Registered ECC stability at 1.2V

The dual-rank x4 organisation and CL17 timing operate at the standard 1.2V DDR4 voltage, keeping power draw predictable in populated memory channels. Registered buffering reduces electrical load on the memory controller, helping thermal headroom in dense configurations. No active cooling or special airflow requirements are introduced by this module.

Single-module upgrade path

The box contains one 288-pin RDIMM, allowing precise capacity increments per slot. Factory-original compatibility with the listed Dell part number simplifies qualification and avoids firmware mismatches. Systems that demand matched kits or specific rank populations per channel must be planned separately.

Questions about this item

How do I install the 288-pin RDIMM in a Dell server, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify the system registers 32GB at 3200MHz in BIOS; skipping the BIOS check is the common oversight.

What maintenance or replacement will this 32GB DDR4 ECC module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails memory diagnostics, replace the single 32GB stick — it is not sold as a matched kit.

What limit appears first when this CL17 dual-rank RDIMM runs sustained workloads?

The CAS latency of 17 cycles at 3200MHz sets the timing floor; thermal throttling or voltage limits depend on the server platform, not the module alone.
