HP Z420 Gaming Computer and other Upgrades
HP Z420 GAMING COMPUTER AND OTHER UPGRADES
The HP Z420 has all the base components to be converted in to a high end gaming computer. HP Z420’s are a single socket Xeon based workstations. They have a standard 400W Power Supply with an optional 600W Power Supply. We have a video that will show you how to upgrade the power supply if you need more wattage for your graphic card of choice. Let us show you how you can build an effective HP Z420 Gaming Computer.
Where to buy?
If you haven’t already acquired an HP Z420 Workstation we’d recommend checking out a company called Serverworlds. They sell the Z420’s cheap and they provide free ground shipping to the lower 48 states. You can configure a custom HP Z420 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 Z420 with a good processor 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 have system board PN 619557-001 aka 618263-001, you can only install V1 Processors
Xeon QC E5-1620 3.6Ghz 10MB 130W Processor | 3.8 Max Turbo Frequency (SR0LC)
Xeon QC E5-2643 3.33Ghz 10MB 8GTs 130W Processor | 3.5Ghz Max Turbo Frequency (SR0L7)

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.

The stock fans are OK, but there is much more noise than the z220 that I had earlier. I did some messing around and found the culprit to be the memory fan. I did some looking at that fan and saw it has four wires instead of the normal 3. I googled the part number to see if I could get a replacement and all I could find were three wire fans with the same part number. I understand that three wire fans are for PWM signal to adjust the RPM. What's the fourth wire?
Not sure if this is the correct place, but I'm trying to move a Z420 into a new case, I've installed a new power supply and graphics card and I am getting an error that seems to be common to those attempting this:
921- Front USB not connected
939 - Front USB 3.0 Not Connected
940 - Front 1394 Not Connected
I've taken the Blue USB connector from the new case and plugged it into the Z420 Blue USB connector port and attempted to boot up, getting the above errors.
I've read that you can "short out" two pins on the blue USB port to resolve USB errors, but I was hoping to be able to use the USB ports on the new case, rather than fooling the motherboard into booting (by shorting the pins) and then not being able to plug the cases blue USB connector into the motherboard if I short out the pins and take up the space the connector requires to connect to the motherboard.
Currently, I can't get the Z420 to get past this error, hitting the F1 key to continue bootup appears to do nothing, the computer remains frozen, and I have officially hit the frustration point ;-)
Can someone direct me to the "fix"?
Jason Kimball You should hit up our discord channel. There are multiple community members that have successfully swapped a Z420 in to an ATX case. They might be able to provide more info.

Runs all my games with high settings on a 34" ultrawide monitor (2560x1080) at 60-120 fps. Looking to pass this down to my kid who's just got into PC gaming, currently on a 4th-gen i7 & GTX 750 ti.
I'm looking at the HP Z440 as my next platform.
The best graphics cards for these chassis types are those with blower-style shrouds. Hot air is forced out the back, while typical aftermarket cards just circulate the hot air, and it's up to the single CPU/chassis exhaust fan to expel the extra heat.
Another idea is to get a liquid cooler graphics card, such as the EVGA Hybrid series. Then you can cut an opening on the side panel to mount the radiator and fan. This is my plan for my next rig.
With 16GB x 8, you can achieve a max memory of 128GB, but because of registered ecc module design, the speed of the memory will clock down.
However, the z420 also supports load-reduced registered ecc modules (LRDIMMs), and there's two distinct advantages I've found. One is that you can exceed 16GB modules and use 32GB ones for a total of 256GB (I have this installed in my z420), and the second is that the modules will run at full speed with no clocking down.
Pairing this much memory with a high core count cpu can make for a nice system for virtual machines.
Hi there, I've got a HP Z420. Can anyone tell me how i can find out which version motherboard i have, PN 619557-001 aka 618263-001 :V1 or PN: 708615-001 : V2 I cannot find it in bios or printed on the Motherboard. I'm guessing i've the V1 as my CPU is E5-1620 but don't know for sure and therefore don't know if i can upgrade to faster V2 CPU's. Any advice welcome and Thanks in advance
I recently ordered a 860 EVO 2.5 500GB drive for a Z420 that was given to me last week. Good ole Amazon shipped me a 860 EVO SATA M.2 1TB drive instead. I see that it isn't possible to boot to the NVME drive via the PCIE adapter as mentioned above, but is it possible for the machine to boot to this SATA M.2 via a 2.5" adapter in the usual HDD spot? I'd rather not return the 1TB drive for a smaller drive, and I know I came out ahead in the deal. If anything, I'll just order another 500GB 2.5" and hope I get the right one next time.
Something like this?
Thanks in advance
Hi, I'm getting ready to swap out the stock graphics card in my z420 for this: GeForce GTX 1050 Ti DirectX 12 GTX 1050 Ti GAMING X 4G 4GB 128-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready ATX Video Card I've been reading up on how best to do this and I've run across some sites that say I'll need to get a 2x6 pin to 1x8 pin adapter. Is this correct? Also, I'm not upgrading the 600w power supply. Will it work with this card? Thanks for your help.
I wanted to give you a heads-up about your video for installing a new GEForce 1050 graphics card in the HPz420. I think you should redo it. You should let people know that if they have Bitlocker encryption on their MS account, they won't be able to boot up without the encryption key. None of the videos I viewed from anyone said anything about this and now I can't use my computer because the encryption key is on a file in the computer. I tried retrieving it through my tablet in my MS account and it acts like it doesn't even know hat I'm talking about. Being someone who is used to using computers and not doing a lot with hardware, etc., I had no idea i'd need that information before doing the upgrade. Now I can't even boot the machine up and i'm looking at a $200 to $400 repair bill I can't afford. Oh, and I also use this machine to work remotely due to COVID. It's really dangerous to throw a video out there thinking the person viewing it is educated enough to know about the hidden dangers. By the way, the card went in successfully, all of that info was correct. I just wish it hadn't cost me my livelihood.

I have no Ram fan,
When I turn psu power both graphics card and cpu fan jiggle a bit but never start spinning full revolutions. The blue light by the Mem Fan turns on twice. I can get video later. Any solutions or anyone with similar problems?
Hi! I'm new to your website and was drawn to it because of the information you offer regarding graphics cards. But upon further investigation, I am unsure if my processor is compatible.
I have a HP Z420 that is multi-core with Intel Xenon E5-1680 v2 @3.70 GHz. Would I need an upgrade in CPU for one of the cards you listed above? Would I be better off buying a new computer?
Waiting for your reply. Thank you in advance for responding!
Not sure about which gpu. There are many listed there and they aren't the newest models out there. That cpu is a great one. Should actually be able to overclock that a bit using throttle stop or atleast get an all core 3.9 turbo. I would imagine any restrictions you may have with a gpu is going to be space and power requirements. But if you can do an all core 3.9ghz you can still bottleneck it with something but I wouldn't worry much.
Thank you for your prompt response!
Perhaps, I should explain my current situation. I recently downloaded SONY Vegas 18 software. My current graphics card is the Nvidia Quadro K2000 which contains 2 GB of memory. I became interested in upgrading my card because I need at least 4 GB for 4K editing and rendering.
Hope this helps.
