I had the Xtreme variant for a couple of days. Flashed the F4 beta bios to get the 150% power limit and ran a bunch of OC configs using Afterburner 4.4.0 beta. Sadly, the card was even unstable when I just increased the power limit from 100 to 125% or higher while leaving everything else untouched. I also tested the Aorus Engine sofware (hint: don't forget to update to latest version!) where Gaming and OC mode also led to crashes.
I have the beta bios and the power target only goes to 125%. Like mentioned in other you have to run "C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -q -d in command prompt and it will tell you the power settings, even with the same BIOs it seems like some cards have 250W +50% or 300W +25% so it is the same.
Just an FYI for everyone, the BIOSes that are floating around for the Aorus XTreme and non-XTreme all have the same 375w maximum with the TDP slider set all the way to the right.
The ones with a +50% adjustment range have the stock FE 250w default TDP limit (this looks to be the BIOS that most of the reviewers got, and is the one posted to TechPowerUp's database)
The ones with a +25% adjustment range have a 300w default TDP limit, but adding +25% gives you the same 375w maximum.
So don't worry if your slider only goes up to +25%, you're actually better off out of the box anyway.
So you are basically saying there is no point of flashing the bios?
I'm on my last airplane and then I have another hour ride home and then I can finally tear that box open and hopefully able to fit it right below my water cooled 980 Ti. I have no interest in draining the loop right now. I just want to slide it under the 980 Ti until the water block comes out. I have a feeling I'm going to run into issues though. Maybe I'll be the first person to use a 980 Ti as a physics card ha!
