HPZ$ G5 Workstation -Graphic card issuE

[abbottwhite]

I have just received my HP Z4 G5 TWR & GFX NVIDIA RTX A4000 16GB 4DP Graphic card

However I discovered that the card can not work in the unit WITHOUT an additional fan ?

Can anyone confirm this is the case?

What work station model can use this card without an additional fan?

How did you discover that and what error message do you get?

I bought a Z4 G5 three weeks ago (523U4EA) and it came with the RTX A4000 as well and the computer worked from the start with no issues or error messages saying that i need another fan. 

However, if you add more RAM you will get a error message when you boot if using +32GB sticks. It promts you to add the Z4 Memory Cooling Solution. No such requirements for GPU. I replaced my RTX A4000 with a RTX A5000 one day later and it worked apart from the nonsens-BitLocker security blah-blah that locked me out of my own computer until i gave it the recovery key.

Did you buy the computer without GPU and then added the RTX A4000 and now it wants you to add a front chassis fan?

Give us the error message/s and we can hopefully guide you to a solution. 🙂

My specs:

OS: Windows 11 Pro

CPU: Intel® Xeon® W 2465X

RAM: 64 GB RAM

GPU: NVIDIA® RTX™ A4000 (16 GB)

SSD: 1 TB SSD

Hi Roger,

thank you the swift response, i have it working now , it was not connected properly to the cable.

i do have another question though, i have an HP  Thunderbolt card and it has an auxiliary cable that connects to a 7 pin socket, I had this socket on my old HP workstation motherboard but i can not locate it on the Z4 G5., can ths card run without the cable?

no, add-in thunderbolt cards required a motherboard that has the necessary TBolt header on the motherboard

some newer motherboards' can also have "Thunderbolt over USB-C" integrated on the motherboard along with USB 4 capability

Yes, a DGroves wrote the cable must be connected. It should be a paper with instructions in the box of the TB card. I have not yet found the instructions online for the Zx G5 series.

On the Z4 G4 the header on the motherboard is labeled PD129. Don´t know if it is labeled the same on the G5 motherboard though.
