Z840
Microsoft Windows 10 (64-bit)

Hi,

 

I have a Z840 with Nvidia Quadro k1200 that was working fine. It was in an old bios release (2.16) and updated to the last one 2.48 and since that Nvidia Quadro was not detected. I had the 6 beeps.

 

I tried almost everything...

- Move to another slot ... Other Nividia (GT 1030) is working fine.

- Change bios parameters, even do a clear cmos etc ...

 

I also tried to downgrade again to the oldest bios in the web and nothing worked. As said, i have another Nvidia card that is working. Any clue to recover my Quadro k1200 in the system ?

 

Thanks a lot in advance.

the video card ROM firmware is not UEFI compliant. When the system has been set to only boot using a UEFI compliant video ROM, and no UEFI compliant video ROM is available, the system is unable to activate the video card.
To resolve the issue, use the "Clear CMOS" button located on the system board. The exact location of the button varies slightly by workstation and is documented in the diagram on the inside of the side panel as well as in the service manual.
NOTE: Clearing CMOS will return all BIOS settings to default settings. Any customizations will need to be re-entered and saved.

 

or simply insert working card, and enter bios and disable UEFI only video (set to legacy enabled) save, power off change cards and power back on
