Saw that there was a vbios here,  but some people were reporting issues with that vbios in another thread, with lower boost clocks and strange voltage behavior. Has anyone that has installed this vbios had no issues? I want to load it for correct fan profiles, but since I don't have a vbios updated to roll back and no dual vbios I'm afraid to do it given the reports here:

Thanks, I would love to know this too. Did you use nvflash to flash that version? Any particular guide or thing that needs to be done?

I tried it, It gave odd software readings on my card of 9V and 10V on the 12V rail which caused lower boosts.

Went back to the 1000W bios.
I just ran the hybrid bios to see if it would get better results then the stock one for more info for my zero to hero 3090 XC3 thread.
It was worse in every way.

I have uploaded my original BIOS   from RTX 30902ACX3 Hybrid  to Techpowerup. , so, it is possible, that you have  downloaded  BIOS  from me. If needed, PM me  and I ll send it to you.

Yeah I'm on a 3080.

Sorry, I got 3090 , my bad.

Me too, I've tried pinging Jacob on Twitter about this but no reply. The techpower up vbios seems awesome, the card boosts even better than before, and it seems to run slightly  cooler too. I've only been running with it for today but I can already match my best benchmark runs, whereas previously I was getting lower scores.

I guess the question is more if the factory version is bugged. Are people reporting the same issue with their XC3 hybrids? If not, it would suggest that the might not have the same vbios. 

But why is update.exe a higher version number? And also, why is EVGA providing that one which is clearly bugged as the update for the hybrid kit for the XC3?

Jacob claims that the one from the updater is the factory one, I asked him on Twitter. But that would mean that the hybrid cards have issues from factory.

Also, the techpowerup vbios does not prompt for firmware updates in Precision X (the udpater.exe one did). Which might mean that we could lose out on potential firmware fixes in the future?

Bios is independant of firmware updates so wont make any difference.
PX1 polls the ICX MCU with I2C command on start up and pulls the version number of the firmware. Then checks the firmware folder if there is a higher version.
Aslong as your Bios has the EVGA product tag or your using the modded Libarary.dll Iv provided to unlock all cards for ICX i2c commands (here) then it will be no different.
I went over this more in the info on how to disable firmware updates in the PX1 forum since they seem to cause people more issues then they fix, And if it fails a update then your cards bricked.

Im sure they are aware of the issues in the update.exe bios since it use to be pinned with its own topic as well as having download links on the support page for the hybrid kit which got deleted.
Now you can only find the links in a post that got missed when they were removing the others.

I got the MCU firmware update when I launched PX1.

What firmware version do you have? I have 6.01.05.

I have the same firmware version.
