The HP Z440 Workstation has all the base components to be converted in to a high end gaming computer.  HP Z440’s are a single socket Xeon based workstation.  The HP Z440 also supports DDR4 memory and NVME.2 Technology.  Ideally you’ll want to install the optional 700W Power supply before you start buying components.  Let us show you how you can build an effective HP Z440 Gaming Computer.

Where to buy?

If you haven’t already acquired a HP Z440 we’d recommend checking out a company called Serverworlds.  They sell the Z440’s cheap and they provide free ground shipping to the lower 48 states.  Custom configure an HP Z440 using this link: Customize a HP Z440.  You can also try to snag them cheap on Ebay.  However, Ebay can be a bit of a gamble because you never know what you are going to get.

The goal is to purchase the Z440 with a good processor(s) and memory already installed and then you can source the graphics cards, hard drives, and other optional components from other sources.


Upgrade your Power Supply:

Optional GPU Fan (J9P80AA)


What Processor(s) should I get?

High Clock speed cpu’s are the way to go.

In most cases you can get by with a QC processor listed below.  If you plan to stream your gaming on youtube or twitch, we recommend getting an 8C or 10C processor.

Recommended Processors:

Up to 1 x QC Xeon E5-1620 V3 3.5Ghz 10MB Processor | 3.6Ghz Max Turbo Frequency (SR20P)

Up to 1 x QC Xeon E5-2637 V3 3.5Ghz 15MB 9.6GTs Processor | 3.7Ghz Max Turbo Frequency (SR202)

Up to 1 x 6C Xeon E5-2643 V3 3.4Ghz 20MB 9.6GTs Processor | 3.7Ghz Max Turbo Frequency (SR204)

Up to 1 x 8C Xeon E5-2667 V3 3.2Ghz 20MB 9.6GTs Processor | 3.6Ghz Max Turbo Frequency (SR203)

Up to 1 x 10C Xeon E5-2687W V3 3.1Ghz 25MB 9.6GTs Processor | 3.5 Max Turbo Frequency (SR1Y6)


How much Memory should I get?

The base line should be a minimum of 16GB of memory.  However, 24GB to 32GB would be ideal.

Memory PNs:

4GB 1Rx8 2400T DDR4 ECC Reg Module (K67DJ)

8GB 1Rx8 2400T DDR4 ECC Reg Module (888JG)

16GB 1Rx8 2400T DDR4 ECC Reg Module (HNDJ7)

32GB 2Rx4 2400T DDR4 ECC Reg Module (CPC7G)

64GB 4Rx4 2400T DDR4 ECC LR Module (29GM8)


Recommended Memory configurations:

4 x 4GB PC19200R ECC Reg Modules (16GB)

6 x 4GB PC19200R ECC Reg Modules (24GB)

4 x 8GB PC19200R ECC Reg Modules (32GB)

6 x 8GB PC19200R ECC Reg Modules (48GB)

It’s very important to use 19200R modules because they will run at the max speed supported by the system board and processor(s).


What Hard Drive should I get?

Ideally you would want to have a NVME.2 Solid State Drive as your boot device as well as storage for faster read speeds.  If you are limited on budget you could go with a small SSD for your boot device and a larger capacity 7.2K SATA drive to hold your larger files/programs/games.


NVME.2 PCIe Adapter (You need this if you plan to install an NVME.2 Drive in to this system):

NVME.2 SSD Adapter *Required to Install NVME.2*


Recommended NVME.2 SSDs:

YES, the NVMe.2 SSD is bootable on a Z440 Workstation

Samsung 970 EVO Series – 1TB PCIe NVME – M.2 Insternal SSD (MZ-V7E1T0E)


Recommended large Capacity SATA Drives:

Seagate 2TB BarraCuda SATA 6 Gb/s 7200 RPM 64MB Cache 3.5 Inch Desktop Hard Drive (ST2000DM006)

Seagate 3TB Barracuda SATA 6Gb/s 64MB Cache 3.5-Inch Internal HDD (ST3000DM008)

Seagate 6TB IronWolf SATA HDD 6Gb/s 256MB Cache 3.5″(ST6000VN0033)


Recommended SSD Drives:

Samsung 860 Evo 500GB 2.5 inch SATA III Internal SSD (MZ-76E500B/AM)


What Graphics Card should I get?

*Make sure to upgrade your HP Z440 to the optional 700W Power Supply before upgrading your graphics card*

Recommended Graphics Cards:

EVGA NVIDIA GTX1660 Ti 6GB Graphics Card

EVGA NVIDIA GTX1070 8GB SC Graphics Card

EVGA NVIDIA GTX1070TI 8GB Graphics Card

EVGA NVIDIA GTX1080 SC 8GB Graphics Card

EVGA NVIDIA GTX 1080 Ti 11GB Graphics Card

EVGA NVIDIA RTX 2060 6GB Graphics Card

EVGA NVIDIA RTX 2070 8GB Graphics Card

EVGA NVIDIA RTX 2080 8GB Graphics Card

EVGA NVIDIA RTX 2080 Ti 11GB Graphics Card


What type of Monitor should I get?

Ideally it would be nice to get a monitor with a 144Hz or 244hz refresh rate or better monitor.  However, it really depends on the games you play.  If you play first person shooter games a 144hz or 240Hz or better monitor is a must.  If you play other games that do not require quick response time then a 60hz monitor should work fine.

Recommended Monitors:

ASUS PG248Q Full HD 144Hz 1MS 24″ Gaming Monitor

ASUS VG278Q Full HD 1080P 144Hz 1MS 27″ Gaming Monitor

ASUS XG258Q ROG Strix 24.5″ 1080P 240Hz 1MS Gaming Monitor
