HP Z640 Workstation – Xeon E5-2680 v4, 32GB RAM, 1TB Micron SSD, Quadro M2000 4GB

Yes. The Z640 supports two processors, with the second CPU fitted on HP's optional processor and memory riser, which also carries its own DIMM slots. For a dual configuration the second processor should be a matching Xeon E5-2600 v4 model, and the riser, heatsink and fan assembly are required. The power supply rating should also be checked against the combined CPU and GPU load.

The Z640 takes registered ECC DDR4 modules. The Xeon E5-2680 v4 supports DDR4 at up to 2400 MT/s, and mixed-speed modules will run at the speed of the slowest installed. For best bandwidth, populate memory evenly across the channels of each installed processor and use modules of the same capacity and rank.

The Quadro M2000 is an entry-to-mid professional card based on NVIDIA's Maxwell architecture, with 4GB of GDDR5. It runs NVIDIA's professional drivers, which are the basis of ISV certification for CAD and BIM applications. It handles 2D drafting and moderate 3D assemblies well; large assemblies, real-time ray tracing or GPU rendering call for a higher-tier card.

The Quadro M2000 has four DisplayPort 1.2 outputs and can drive four displays at once. Monitors with HDMI or DVI inputs can be connected using DisplayPort adapters. DisplayPort 1.2 supports 4K at 60Hz per output, so a multi-monitor 4K desk is possible within the card's 4GB memory budget.

All three use the LGA2011-3 Xeon platform. The Z440 is a single-socket tower, the Z640 adds dual-socket capability through its CPU riser in a mid-size chassis, and the Z840 is the larger dual-socket model with more memory slots, drive bays and expansion slots. The Z640 sits between them for users who want a second CPU option without the Z840's size.

With 14 cores and 28 threads, the E5-2680 v4 gives plenty of vCPU capacity for running several virtual machines on a workstation, and it supports Intel VT-x and VT-d for hardware-assisted virtualisation and device passthrough. In this build, the 32GB of memory is more likely to limit how many VMs run at once than the processor.

The listing identifies the drive as a 1TB Micron SSD, but the exact model and interface have not been confirmed. If the interface matters for your deployment, for example when planning a drive clone or adding storage, ask for the drive model number before ordering so it can be checked against the label.
