Quad-socket Xeon server with 512GB memory

The Dell PowerEdge R940 is a 3U rack server that holds four Intel Xeon Gold 5120 processors running at 2.2GHz with 14 cores each. It ships with 512GB of DDR4 2400MHz registered ECC memory across 16 modules. Eight 800GB SATA SSDs and a PERC H730P 2GB controller provide storage, while dual 1600W platinum power supplies deliver redundancy.

Suited for dense compute workloads.

This configuration suits environments that need high core counts and large memory capacity in a compact rack footprint. Buyers who only require one or two processors should look at smaller platforms that cost less and consume less power. The system maxes out at four CPUs, so it cannot scale beyond the installed sockets.

48 DDR4 slots support up to 6TB total capacity

The server includes 48 memory slots populated with 16x 32GB modules, leaving room to expand toward the 6TB maximum. Each slot accepts DDR4 registered ECC DIMMs, so upgrades must match that specification. The existing 512GB installation already occupies one third of the available slots.

Questions about this item

How many DIMM slots remain free for future memory upgrades beyond the 512 GB already installed?

The system has 48 total DDR4 slots and 16 are populated with 32 GB modules, leaving 32 slots available for additional registered ECC memory.

Which component reaches its maximum capacity first when all four Xeon Gold 5120 processors run at full load continuously?

The four-socket limit is already reached with four CPUs installed, so processor scaling cannot go further; thermal headroom and the 1600 W redundant power supplies become the next constraints.

What is the typical acoustic and thermal profile when the dual 1600 W platinum power supplies and all drives operate 24/7?

Redundant 1600 W platinum units and hot-swap fans keep the 3U chassis within Dell's specified thermal envelope; exact decibel and temperature figures vary with inlet temperature and workload.
