Just to add to the mix.  Precision X1 worked fine for the 3070 FTW, but when I added a 3080FTW to the same build it would no longer scan; stayed at 0% forever (overnight).  Shouldnt be power, unless the 1300W PSU can't handle these cards.  Removing the 3070 and scanning the 3080 alone worked for a bit - then the system rebooted.  The event log error from was event id 4101 - "Display driver nvlddmkm stopped responding and has successfully recovered."
 
This is AFTER I followed the FAQ to uninstall everything (DDE, X1, Drivers); cold boot with 5 minute rest to drain the GPU cards, etc.
 
Currently driver 460.89, X1 is v1.1.1.4, current edition windows 10, etc...
 
 
 
 
 

I noticed an issue present since all the new Precision x1 versions for the RTX 30 series cards. While PX1 is idle in the background it is using around 0.5-0.9% cpu usage. I had an older version on PX1 with my 2080 TI XC Ultra that did not do this. It would idle at constant 0% cpu usage.

main problem right now with PX1 is i have a noctua 200mm Fan hooked up to the header. upon start of PX1, it doesnt pick up the ext fan since its not spinning. I literally ahve to open the front panel of my case, manually spin the fan and start PX1 so it will pick it up.

That doesn't sound like a PX1 issue but an issue with the Header being able to start the fan.  When fans initially start they require quite a bit more power vs when they are just running.
Move the fan to a different header like on your motherboard and I bet that problem goes away.

App still keeps crashing when I attempt to open it

that's what i thought too but this only happens at the FIRST start up, from reboot/shutdown. As long as the app has picked up the fan, even if i come from sleep mode after like 8 hours, 0 problem, the fan spins.

RTX 2070 Super, OC Scan goes from 0% to 254% and gives me a failed result.

• Fixes crash on opening due to profile mismatch
• Fixes issue where the VF Curve does not save correctly

 
Unfortunately the VF Curve still has some save issues. But improvement so far is greatly appreciated. 
 

 
Yep this is what I'm also experiencing with as well on the RTX 3090 FTW3 Ultra, so basically the software does not like what we told them to do. 

If you set VF Curve, and save the profile, then set custom fan speed at a percentage, and apply. After that the VF Curve just magically goes back to default.

- X1 never loads a profile on startup. Ever. I always have to manually load a profile after boot, or even a restart of X1, despite having 'Start with OS' and 'Apply previous settings on load' checked.
- Chain link icon for fan speeds always has to be manually reapplied after I load a profile.
- GPU temp in system tray is too small for anything other than a cyborg with magnified ocular implants to read. This was never a problem in versions of Precision prior to X1.
- No settings of any kind can be made to display on Logitech LCD's. Another issue that was not present in versions of Precision prior to X1.
- 'Show profile in tray menu' does nothing. There's no separate display in the tray, and nothing on mouseover or right click of the X1 icon in the tray. It won't even stay selected between startups. Versions prior to X1 worked fine.
 
 

More info on not being able to scan, since I haven't seen anyone else post this.
 
Reading that the OC scan in X1 is really a nvidia tool that everyone is using, I tried to run the nvidia overclock tool on a system with a 3070 and 3080 installed.  The tool responded with a message that scanning for overclock with more than one video card present wasn't supported.   Pulled the 3070, scanned the 3080 - moving on with my life. 
 
You could have just said that it won't scan with 2 cards installed.  
 
FWIW - having the same issues as everyone else with saving fan profiles. 
 

I'm also having issues with the X1 OSD not hooking into any DX12 games I've played. 
 
I've tried Anno 1800, F1 2020, Forza Horizon 4 and Hitman 2. 

Lately Precision X1 will not save settings at all on reboot. I've done the 'set everything, exit and reload' trick, and it still returns to default on reboot. Yes, the 'apply overclock settings on startup' is checked. Fresh install of Win 10.
