SOLVED - ASRock x399 Pro Gaming - 4G decoding Bios setting

[jjackstar1]

Hey all,
I have spent the afternoon updating and trying to find the 4G decoding setting to enable my system to boot with a Tesla M40 installed.
running the latest bios version.
I saw that this setting was available on the TahiChi board but does not appear to be on the pro gaming board. If anyone has any ideas they would be much appreciated.

PC will not boot with tesla M40

Hi everybody, I bought a tesla m40 24gb card via ebay for some machine learning. However ones i install the card the PC will not post. The PC is a Dell Precision T5600 2x Xeon E5-2620 2.0Ghz 16GB Ram and the GPU to drive the monitor an old nvida quadro card. on a side note. I used the 8 pin GPU power connector which plugs into the m40 adapter and then into the GPU it self. should i be using a CPU 8 pin connector into the adapter? any ideas why the PC wont post?

If not giga can probably help just @ him here if that doesnt help

I saw that post and that was what prompted me to look into 4G decoding.
The issue is that I can not see the setting listed in the bios to enable it.
Bios just updated to v3.8

you’ll have to do some googling to fine tune the specifics

you’ll also need to be running GPT on your storage and something about CSM I forget, its in the other threads

Thank you for all your help @GigaBusterEXE
Got the card working!
After disabling CSM in the UEFI the option to enable 4g decoding appears and the system booted right up after that

Once again thank you so much for the headache you saved!
