Condition - HP Z640/Z840
The Z640 and Z840 are the current models in production by HP. We acquire the workstations new from corporate vendors around USA. Similarly, the components we install are new. We have different vendors for processors, memory, solid-state drives, hard drives, graphics cards, etc. We have focused on creating this extensive list of vendors to provide the best condition and quality components. The workstations we purchase include base configurations. Once we receive your order, we will use a new, base configuration, workstation and upgrade it to your unique specifications.
Condition - HP Z600/Z800 and Z620/Z820
These models are no longer in production by HP, so it's difficult to find them in new condition. Our workstations are pre-owned by professional institutions including large video editing companies, and governmental/educational facilities. We do not use the term 'refurb' because refurbished items by definition are faulty then repaired/refurbished to working condition again. Our inventory comprises of only workstations that were used by a company, then upgraded. This occurs frequently because larger corporations have every 2-4 year system replacements within their budgets.
Cosmetically, our units are in good condition (majority still have the new plastic wrapping on the side casing). Our vendors have learned that we are paranoid about the cosmetic condition we acquire. They know that we will complain if they send us poor condition units, so they directly pass it on to our competitors. We never sell units with bends or dents. Units might have light scratches and/or scuffs. If you would like to know the condition of the specific unit you will receive, please contact us with your configuration as our inventory changes on a daily basis.
Components: If the component is currently in production, we only buy new condition. For examples, memory, hard drives, and solid-state drives are new. As well, the late model graphics cards and majority of the expansion cards / accessories are new. Mainly, only the processors are not new because Intel no longer produces these generation processors. Since the processor is one of the vital components in the workstation, we purchase only from facilities which pulls processors directly; we never purchase from a 'middle man' company. We also inpect the processors to be in Grade A condition. Any component not exceeding our expectations is returned to vendor.
- We purchase only from professional, government, and educational facilities. We never purchase individual units from home users because we found the condition to be lower (excess dust / stench of smoke). The companies we purchase always have non-smoking and clean facilities.
- All units are examined, tested, and cleaned when they arrive at our location. Once customized, they are tested again.
HP Z640/Z840 - Base vs Recommended
There is only one generation/model Z640 and Z840 produced by HP which are compatible with both the Intel Xeon E5 v3 'Haswell' and E5 v4 'Broadwell' processors. The 'Base' and 'Recommended' configurations consist of the same chassis and components. The only difference is the offering of standard range processors on the 'Base' configuration tool and upgraded/higher performance processors on the 'Recommended' configuration tool.
HP Z620/Z820 - Base vs Recommended
HP produced two generations of the HP Z620/Z820.
- First Generation
- Year 2010/11
- Processor: Intel Xeon E5 v1 (Intel Code Name: Sandy Bridge-EP)
- Memory: DDR3 1333MHz
- Second Generation
- Year 2011/2012
- Processor: Intel Xeon E5 v2 (Intel Code Name: Ivy Bridge-EP)
- Memory: DDR3 1866MHz
Processors - Intel Xeon E5-1600 vs E6-2600 series
The main difference between the E5-1600 v3/v4 series and the E5-2600 v3/v4 series is single socket vs. dual socket motherboard compatibility. If you plan to purchase a single processor Z workstation and do not intend to add a second processor, the E5-1600 series processors are fine. If you decide to run a dual processors, the E5-2600 series is your only choice. For many applications such as Adobe Photoshop and Autodesk AutoCAD which rely heavily on the single core rather than multi-core, the single processor 6- or 8-core E5-1600 series is fine because you will never achieve improvement by adding a second processor.
As well, the E5-1600 series provides you with a 15MB cache, while the E5-2600 offers 30MB. This larger sized cache is perfect for applications that rely more on CPU rather than GPU.
Graphics Cards - NVIDIA vs. ATI
NVIDIA has proven themselves as the leader when it comes to performance and technology for performance workstations. Their video cards are consistently more aggressive than the competition. But besides the raw horse power, NVIDIA’s eco-system of different technologies such as: PhysX, CUDA, and 3D Stereo Glasses, revolutionizes the professionals productivity. This is exactly why ZWorkstations.com recommends NVIDIA.
SSD vs. Flash Storage
We purchase and install only:
- New condition drives - The drive is like the brain of the computer. It holds your operating system, applications, and data. Used drives offered by our competitors can have thousands of usage hours which can cause the drive to fail earlier and lacks the reliability of a new drive. This is why our drives are brand new or pulls from brand new systems.
- Samsung branded drives - Samsung is known to be the manufacture the highest quality and performing solid-state drives in the market.
- Solid State Drives (Samsung EVO/PRO 850) are based on SATA 3 technology which performs at 6GB/s and more specificatlly about 550MB/s.
- Flash Storage Drives (Samsung SM951/SM961 NVMe ) are based on PCIe technology. NVMe PCIe drives are the latest and fastest on the market. The SM951 drives perform at about 1250-1750MB/s while the newer SM961 drives perform at 1500-2500MB/s. These exceed the performance of Intel Enterprise drives which cost multiples more.
Thunderbolt does not come standard with the HP Z Workstation. HP manufactures a PCIe Thunderbolt card that has one Thunderbolt 2 (20GB/s) port. It is compatible with all HP Z640/Z840 units and the 'Recommended' HP Z620/Z820 units.
Thunderbolt is not compatible with the 'Base' HP Z620/Z820 units or the HP Z600/Z800 units. These models come with onboard USB 3.0 (5GB/s). USB-C (10GB/s) and eSATA (6GB/s) are optional via PCIe.
The Z620/Z820/Z640/Z840 come standard with USB 3.0.
An optional 4-port USB 3.0 card is available for Z600 and Z800 models.
We also offer:
- USB 3.1 - Latest technology. Also known as USB-C. Performs at 10GB/s. Double the performance of USB 3.0 (5GB/s)
- eSATA - an earlier port for external hard drives. Performs at 6GB/s, but majority of hard drives now come standard with USB 3.0 instead since it's more universal.
Systems ship with a fresh install of the operating system you select on the configuration tool.
ZWorkstations.com can divide drives into multiple partitions and install multiple configurations upon request. Depending on your configuration and operating systems, there might be an additional charge. Please contact us for more information.
ZWorkstations.com also offers turn-key systems. We can install the professional applications of your choice. Once you receive, you simply enter your user account / registration information then start working. Depending on your configuration and applications, there might be an additional charge. Please contact us for more information.
Unfortunately, the Mac operating system (OS) is not compatible with the HP Z Workstations because the Mac OS does not have the HP Z Workstations hardware drivers. Mac OS can only be run on specific PC hardware as a 'Hackintosh' because Apple incorporates only specific drivers within the operating system. Because majority of the hardware in the Z Workstations are newer technology than Apple offers, it's not possible to run the Mac OS.
If you require a powerful editing workstation, but Mac OS is a must, please visit our other company iBuildMacs.
Custom Builds - Thunderbolt 3 / Multi-GPU
The HP Z Workstations are great because HP spends millions on research and development. They are solid workstations. After customizing hundreds of HP Z Workstations, we've encountered a couple faulty power supplies and motherboards. With the brilliant HP design, it literally takes 2 minutes to replace a power supply and less than 10 minutes to replace an entire motherboard. The HP Z Workstation is praised by major studios worldwide.
Unfortunately, while the proprietary HP chassis design allows for easy component replacement, fantastic air flow, tremendous reliability and compatibility, there are a couple limitations:
- The HP Z840 has the option of a 925w and 1125w power supply. By default, we only stock the more powerful 1125w power supplies because we customize performance workstations. However, with each performance processor using 150w and each graphics card using 250w, it limits the number of graphics cards. The Z640 supports two moderate powered graphics cards or one high powered graphics card. The Z840 supports three moderate powered graphics cards or two high powered graphics card. If you are seeking a workstation with more than two performance graphics cards, such as installing three or four or six GTX Titan X graphics cards, we can customize a system using an enterprise motherboard and a super 1500w or 2000w power supply to support an editing monster.
- Similarly, HP has released the Thunderbolt 2 card, but not the a Thunderbolt 3 card. Only Asus currently manufactures a Thunderbolt 3 card, but it is by Asus and compatible only with Asus motherboards.
For the HP Z Workstations, only Thunderbolt 2 and USB-C is available currently.
If your workstation must have Thunderbolt 3 or several high performance graphics cards, we do have custom workstation solutions available. We offer this service to customers who require a component that HP is not compatible with.
If you provide the specifications you are looking for via our configuration tool, we can provide a quote based on a custom built (non-HP) workstation.

There are many different types of sellers out there. Some focus on selling workstations in bulk, some sell base configurations, some sell lower quality equipment in attempt to offer the lowest prices on the market, and others focus on offering the highest quality equipment with support. ZWorkstations.com is obviously the latter type. Other sellers have no cost of researching quality components and latest technology innovations, no time invested in consulting, and no post-sale support costs. Because of those differences, a direct pricing comparison is not possible. If you find a workstation for a lower price, we cannot match the price. However, if you find a completely customized HP Z Workstation with support for a lower price from a reputable company, we do encourage you to approach us about it. Most often, the other company is using poor condition chassis', used or low quality components, or is putting much less time into building the system correctly or supporting it.
ZWorkstations.com is based in Los Angeles, CA -- just a few miles from the intersection of the 101 and 405 freeways near to Sherman Oaks . At this time, we operate as an internet business only, but you are welcome to stop by our location and chat! Without the cost of sales clerks, the monthly rent for a retail facility, and all the associated costs, we are able to greatly reduce our margins on every system we sell. This means lower prices for you. At the moment we are doing quite well in this position, and have no intention of opening a retail facility. It is our primary goal to provide quality systems and great customer service at the fair prices.
Plus, if you are local in Los Angeles, you are welcome to pick up. For quantity orders, we may offer free local delivery.
- HP Z640/Z840 - since these models are new, we typically will use the original HP packaging to ship in. If the unit has lots of configurations which adds weight, we will add more packaging material to make the workstation extra secure.
- HP Z600/Z800/Z620/Z820 - we use double wall boxes with foam surrounding the entire unit. We have shipped HP Z Workstations to many countries across every continent. We will make sure your workstation arrives safely.

Our HP Z Workstations come with a:
- 14-day return period - if you are not happy with your workstation(s) for any reason, please contact us immediately. We will work with you to resolve the problem.
- 60-day warranty period - you can be comfortable with your purchase knowing that in the rare case something happens, we will take care of it. Even after the warranty period, we will be here to assist you. Please see 'Warranty' and 'After Warranty' sections below for more information.
ZWorkstations.com offers a 60-day warranty period on all workstations. We limit our warranty period to 60-days because we strive to maintain a competitive advantage in the marketplace. We can easily offer an one year warranty period on our workstations, but with longer warranty, comes higher support costs for all customers. Thus, we are proud to offer an extended one year warranty period to buyers who require it due to company purchasing requirements or customers who prefer the peace of mind. For more information on the extended warranty, please visit the 'After Warranty' section below.
We acquire our HP Z Workstations from professional facilities and our components are primarily new. Further, we test our workstations thoroughly prior to and after the customization. We are confident our workstations will perform fine for years to come. We test the units for about 45 minutes. In the rare case there is an issue, it will typically occur within the first day or two of starting to stress the unit. If the unit performs fine for the first few days, it will be fine for years to come. This is because if there is a faulty component installed, it will quickly become apparent. Otherwise, the HP Z Workstations are resilient systems and will run strong.
Our competitors install used components, so it is important for them to offer extended warranty periods. If they don't, they will have big problems. For us at ZWorkstations.com, having a faulty component after 6 months or a year is slim to none.
Whether you purchased a workstation from us a week ago, a month ago, or 2 years ago, we offer phone and email support for the duration of you owning the system. We have a tremendous amount of experience, thus can easily diagnose issues...typically faster and easier than HP direct. If your warranty period has expired, we will help diagnose the problem, help locating the replacement component or offer the replacement component directly at cost, and even provide replacement instructions.
We stand by our product 100%. We sell only HP Z Workstations. It's what we deal with all day, every day. When it comes to expertise in the product, other companies cannot compete.
If you are a buyer of a institution that requires a longer warranty duration or you simply prefer the peace of mind, we can offer an one year warranty period on the latest model HP Z640 and Z840 for 10% of the workstation value. For example, if the Z640 build price is $4,500, the one year warranty will be $450. To request this warranty, please contact us.
Customizing systems in large quantities can be more time efficient, so we can pass along those savings in the form of a discount. We consider those discounts on a case by case basis. Contact us for custom pricing if you are ordering 5 or more computers at one time.
Normally, a large quantity does not significantly lengthen our standard 2 to 6 day preparation time. Usually, we request only a few additional days on 10 of more units.
International customers are responsible for all brokerage fees, taxes and import duties. ZWorkstations.com is not involved with determining or collecting those costs. These costs vary by country, so we cannot tell you how much cost to expect. Your local customs agency can provide this information. Your shipping carrier will communicate your final costs for collection just before delivery.
International customers are responsible for shipping costs for warranty repairs or part replacements. ZWorkstations.com is proud to be able to offer our workstations internationally, but the high costs of shipping mean that we can only service other countries to individuals who are willing to accept the potential of these costs.
The HP Z Workstation power supplies are manufactured per international specifications. They are compatible with all international voltages and outlets.
The power cords we provide are for US style wall sockets only. If you require a different style power plug, you must source that cable locally.
