Server-grade DDR4 ECC Registered module

The DELL AA799087 is a 32GB 288-pin DDR4 SDRAM stick rated for DDR4 3200 (PC4 25600) at 1.20V. It targets administrators upgrading or populating Dell PowerEdge and compatible enterprise servers that require registered memory with error correction.

Sustained-load behaviour

ECC Registered architecture corrects single-bit errors and detects multi-bit errors during continuous operation, reducing silent data corruption in virtualisation clusters and database workloads. The 2Rx4 dual-rank organisation helps maintain bandwidth when all channels are populated under heavy, long-running compute tasks.

Installation practicalities

The 288-pin DDR4 form factor fits standard server DIMM slots; registered buffering adds electrical load, so the motherboard memory controller must support registered DIMMs and the specific rank configuration. Mixing registered with unbuffered modules or exceeding the platform's maximum rank-per-channel limit will prevent boot or cause instability.

Questions about this item

How much heat and power does a 32 GB DDR4 3200 registered ECC DIMM at 1.20 V produce under continuous load?

Each module runs at the standard DDR4 voltage of 1.20 V, so power draw and heat output stay within the normal range for registered server memory of this capacity and speed.

What must the motherboard provide for this 288-pin DDR4 3200 registered ECC module to function?

The board needs DDR4 DIMM slots that support registered ECC memory and a memory controller able to operate at 3200 MT/s (PC4 25600).

Will this 2Rx4 registered ECC DDR4 3200 module work in a system that already has registered ECC DDR4 DIMMs of a different speed?

If the platform supports mixed-speed registered ECC DDR4, the memory controller will typically run all modules at the lowest common speed.
