The HP Z620 has all the base components to be converted in to a high end gaming computer.  HP Z620’s are a single socket Xeon based workstations with the option to add a secondary processor riser board.  They have a standard 800W Power Supply, which gives you endless options for high end Graphics Cards.  Let us show you how you can build an effective HP Z620 Gaming PC.

Where to buy?

If you haven’t already acquired an HP Z620 Workstation we’d recommend checking out a company called Serverworlds.  They sell the Z620’s cheap and they provide free ground shipping to the lower 48 states.  You can configure a custom HP Z620 using here.  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 Z620 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.

 

What Processor(s) should I get?

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

*If you plan to do live streaming on a platform like Twitch or YouTube, we strongly recommend installing 2 processors*

Up to 2 x QC Xeon E5-2643 3.33Ghz 10MB 8GTs Processors | 3.5Ghz Max Turbo Frequency (SR0L7)

Up to 2 x 6C Xeon E5-2667 2.90Ghz 15MB 8GTs Processors | 3.5Ghz Max Turbo Frequency (SR0KP)

Up to 2 x 8C Xeon E5-2687W V2 3.4Ghz 25MB 8GTs Processors | 4.0Ghz Max Turbo Frequency (SR19V)

 

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 1Rx4 ECC 14900R DDR3 Module (712381-571)

8GB 2Rx4 ECC 14900R DDR3 Module (715273-001)

8GB 1Rx4 ECC 14900R DDR3 Module (731657-081)

16GB 2Rx4 ECC 14900R DDR3 Module (715274-001)

 

Recommended Memory configurations:

4 x 4GB PC14900R ECC Reg Modules (16GB)

6 x 4GB PC14900R ECC Reg Modules (24GB)

4 x 8GB PC14900R ECC Reg Modules (32GB)

6 x 8GB PC14900R ECC Reg Modules (48GB)

It’s very important to use 14900R 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 Solid State Drive as your boot device as well an NVME.2 SSD to store your game libraries/large programs on.  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.

 

Recommended SSD Drives:

Samsung 860 EVO 1TB 2.5 Inch SATA III Internal SSD (MZ-76E1T0B/AM)

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

 

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)

 

*NVME.2 Drives cannot be used as a boot device with this model workstation*

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:

WD Black 512GB M.2 2280 PCIe NVME SSD (WDS512G1X0C)

EVGA NVIDIA GTX1080 TI 11GB SC2 ICX Technology Graphics Card

EVGA NVIDIA RTX 2080 8GB 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

 

Replacement Power Supply:
