Hello,
Recently reinstalled Windows and only 2 of my graphics cards are running in Octane, while always there were all 4 running previously. Reinstalled Windows many times. Tried manually unplugging and plugging back the video cards, tried many different Nvidia drivers, tried reinstalling Windows again several times and still get the same problem. If I try to enable all devices in octane render settings it won't let me. Only possible to switch 2 cards on out of 4.
Please help.

I am using studio+ (2020.1.5- R4)
Tried few other ones, same problem. And have used this exact one before, and all 4 cards were working. Tried different C4D. Only stopped after reinstalling windows. Tried different drivers etc.

Hi,
2020.1.5-R4 is a Studio version, not Studio+ version.

You need the Enterprise version to have more than 2x GPUs:
