Precision 5820 with 256GB registered ECC memory

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo across four cores. It ships with 256GB of DDR4 2666MHz registered ECC memory populated across eight slots and a 1TB PCIe NVMe solid state drive. The Nvidia NVS 310 graphics card provides dual DisplayPort outputs driven by 512MB of DDR3 video memory. Windows 11 Pro is pre-installed and digitally activated.

Suits memory-intensive workloads.

This configuration serves engineers, analysts and content creators who need maximum registered ECC memory capacity and error-correcting stability for large datasets or virtualization. The NVS 310 is a basic display adapter intended for multi-monitor productivity, not for GPU compute, rendering or modern 3D applications. Buyers who require certified professional graphics drivers or substantial video memory should look at a different graphics option.

256GB DDR4 2666 registered ECC limit

The platform supports a maximum of 256GB of DDR4 2666MHz registered ECC memory across its eight DIMM slots, and this unit already populates every slot with 32GB modules. Any future memory upgrade would require removing existing sticks, so the installed capacity is also the practical ceiling for this system.

Questions about this item

What thermal limit does the Xeon W-2225 hit first during sustained all-core workloads?

The processor runs at a 4.1 GHz base frequency and can reach a 4.6 GHz turbo frequency across its 4 cores; sustained heavy loads will be constrained by the 950 W 80 Plus Gold power supply and tower airflow rather than a published thermal ceiling.

How much acoustic noise and waste heat does the 950 W 80 Plus Gold PSU and NVS 310 produce during continuous operation?

The 950 W supply is rated at 90 % efficiency, so roughly 10 % of drawn power becomes heat; the NVS 310 is a passively cooled 512 MB DDR3 card, making the PSU fan the primary noise source under long-running workloads.

Which display cables or adapters are required to connect monitors to the NVS 310?

The graphics card provides two DisplayPort outputs, so each monitor needs a DisplayPort cable or an active adapter to HDMI, DVI or VGA; the system includes no video cables.
