Problem with HP Z4 + NVIDIA DUAL-RTX2080Ti (Asus)

[VioCip]

I recently purchased a HP Z4 G4 Tower workstation that I would like to use with RTX 2080ti (Asus) video card.
After mounting the video card in the system, it does not boot. I tried with another video card with the same PN and it's the same thing.

I tried with a 1080i video card and it's all OK.
Do you have any special settings for the 2080s?

The HP workstation specifications are:
HP Z4 G4 90 1000W Chassis for Core-X
Dual 6-plus-2pin Graphics Power Cable
HP Z4 G4 Fan and Front Card Guide Kit
Intel Core i7 7800X 3.5 2400MHz 8.25 6C CPU
32GB (2x16GB) DDR4 2666 UDIMM NECC Memory
1TB 7200RPM SATA 3.5in
HP Remote Graphics Software (RGS) for Z
Windows 10 Pro 64

Does anyone know what I could do to use Z4 with RTX2080ti?

VioCip,

Of the 20,000+ Passmark baselines for HP systems, there are only 7 systems using the RTX 2080 Ti, among which is a single Z4 G4 (i9-7900X) and a single Z8 (Xeon Gold 6146). 

As the knowledge base = 1, that means it's possible to use the RTX 2080 Ti but having a look on the US HP site:

https://store.hp.com/us/en/ConfigureView?catalogId=10051&langId=-1&storeId=10151&urlLangId=&catEntry...

> there is no option listed for the RTX 2080 Ti.

Without any kind of display faults or error message,  the ideas for the failure are limited. If the system runs on the 1080 Ti, but will not boot at all with the RTX, suggests a problem at the BIOS level as it should be possible to see at least  the BIOS/setup level.

Ideas:

1. HP Remote Graphics Software (RGS) for Z: I  don't know the details of this software, but as it involves control of the graphics subsystem, try running the Z4 with that feature disabled.

2.  Driver Conflict: There could be a driver conflict, but if there is no display with the RTX in place, the only option would be to run the system with the 1080 Ti and run a thorough driver cleaner, then make a clean install of the RTX. If it doesn't boot at that point, it's likely a driver conflict is not the cause.

3. Faulty RTX 2080 Ti:  It's highly unlikely that two identical RTX 2080 Ti's would be faulty but , still, to eliminate that possibility, consider trying those cards in another system.  There have have been a number of reports of RTX 2080 Ti problems, see:

Now, I've run out of wild guesses!
