40-Core Dual Xeon Workstation

The Lenovo ThinkStation P920 Tower combines two Intel Xeon Gold 6148 processors at 2.40 GHz for a total of 40 cores. With 256 GB of DDR4 ECC Registered memory and a 1 TB NVMe M.2 SSD, it targets professional CAD, rendering, engineering and content-creation workloads. An NVIDIA GeForce RTX 3070 with 8 GB video memory drives multi-display visual work. Windows 11 Pro is pre-installed for immediate deployment.

Suits multi-threaded professional workloads

This system suits users who need high core counts and large ECC memory capacity for design, simulation or data-heavy applications. Buyers who require more than two physical processors or a different GPU architecture should evaluate alternative configurations. The tower chassis uses LGA 3647 sockets with a maximum of two processors installed.

Dual Xeon Gold 6148 configuration

The defining specification is the dual Intel Xeon Gold 6148 20-core processors delivering 40 total cores at 2.40 GHz. This CPU arrangement determines the workstation's multi-threaded throughput and the LGA 3647 platform limits future processor upgrades to the same socket family.

Questions about this item

What power capacity must my UPS or PDU deliver to support the dual Xeon Gold 6148 CPUs and RTX 3070 under full load?

The system draws significant power with two 20-core Xeon Gold 6148 processors at 2.40 GHz plus an RTX 3070; choose a UPS or PDU rated well above the combined peak draw of both CPUs and the GPU.

Will my existing DDR4 ECC Registered modules work in the remaining 14 slots alongside the factory 256 GB?

Yes, the tower has 16 DDR4 slots total and 256 GB pre-installed; any additional modules must be DDR4 ECC Registered to match the installed memory type.

How do I confirm both Xeon Gold 6148 CPUs and all 40 cores are active after first boot?

Open Task Manager in Windows 11 Pro, select the Performance tab, and verify two sockets and 40 logical processors are shown.
