Refurbished · Tested
HP Z840 dual CPU workstation barebone tower, a refurbished two socket LGA2011-3 chassis for Xeon E5-2600 v3 and v4 processors and DDR4 ECC memory.
The HP Z840 is the flagship of HP's DDR4 generation Z series: a dual socket tower that takes two Intel Xeon E5-2600 v3 or v4 processors in LGA2011-3 sockets, with 16 DIMM slots for DDR4 ECC Registered memory, PCIe 3.0 slots for several full length graphics cards, and internal bays for NVMe, SATA SSD or hard drives. Nothing is fitted: no CPU, no RAM, no storage. With v4 processors of up to 22 cores each, a Z840 can carry 44 cores and hundreds of gigabytes of memory under a desk, which is why buyers in Qatar choose this refurbished chassis for rendering farms, simulation, video post-production and machine learning development. ServerDove keeps it in Doha stock for builds that need server compute with workstation graphics.
WS-HP-Z840-BAREForm factor TowerChassis and platform
The Z840 chassis is HP's largest tower, with a high wattage power supply, a tool-less interior and airflow designed for two high wattage processors and multiple graphics cards. The platform below is the workstation as HP built it.
What you need to add
Server processors and server memory fit this workstation, so a retired 13th generation server is a ready source of both. Graphics cards, heatsinks and storage are workstation parts.
- One or two Intel Xeon E5-2600 v3 or v4 processors with Z840 heatsinks, which use HP's own mounting
- DDR4 ECC Registered DIMMs, four per processor to fill every channel, up to sixteen
- Professional graphics cards in the PCIe 3.0 x16 slots
- NVMe M.2 storage on HP Z Turbo Drive adapters, or SATA SSDs and hard drives in the bays
- An operating system licence
A single processor leaves eight DIMM slots and some PCIe slots inactive. Both processors must be from the same family, and v4 parts need system firmware from 2016 or later.
Compatibility
Processors and memory are common to the Z series of this generation and to 13th generation servers; chassis parts are specific to the Z840.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
