Dual 14-Core Xeon Workstation

The HP Z840 tower delivers 28 cores of Xeon E5-2690 v4 processing at 2.60 GHz with 128 GB of DDR4 memory, built for professionals running CAD, rendering, engineering simulations and other multi-threaded workloads that scale across many threads.

Upgrade from Single-Socket or Lower-Core Systems

Moving from a single-socket machine or a dual-socket box with fewer than 14 cores per CPU adds the parallel throughput needed for large assemblies, heavy scene files and batch compute jobs where memory bandwidth and core count matter more than single-thread frequency.

Installing Drives and OS Is Straightforward

The chassis arrives without storage or an operating system, so you add the drives and OS that match your workflow; the main pitfall is forgetting to populate both CPU sockets with matching heatsinks or skipping the required memory configuration rules for the 128 GB DDR4 kit.

Questions about this item

What motherboard socket does the HP Z840 use for its dual Xeon E5-2690 v4 processors?

The workstation uses two LGA 2011 sockets, one for each 14-core Xeon E5-2690 v4 CPU, giving 28 cores total.

Which memory type and capacity are pre-installed, and what should I check before adding more?

It ships with 128 GB of DDR4 memory; verify the number of free DIMM slots and match the same DDR4 specification when expanding.

Since no drives or GPU are included, what will I need to add first to make the system bootable?

You must install at least one storage drive (HDD or SSD) and a graphics card, then load an operating system before the workstation can start.
