5.3.10 installed okay on my Win 10 x64, but still doesn't retain custom fan profile for SLI configuration once Precision X is closed - have to keep resetting my custom profile unless I never reboot or close Precision X.
 
Have re-installed 5.3.8 for the time being.

The version 5.3.10 have problems with fans nvidia sli mode only works the first GPU fan. Prior to version 5.3.8 did not fail.

It's obvious that biggest problem of Precision X is conflict with some application and than happen different kind of problems.
EVGA need to continue to improve software and reduce influence on different applications. 
With last two version I didn't had crashes any more on end of level in some games during load second but sometimes I lose control on mouse and I see cursor in during game. Than when I Esc in game menu and click on resume control back. It's not often but if someone use software without problems and install Precision X suddenly problems start. It's obvious that Precision X could cause even fps drops if applications behave like that when OSD is enabled. 
From other side 4.2.1 version and Precision X work and no problem with any application.

Confirmed as well!  I have avoided 5.3.9 and 5.3.10.  The SLI fan profiles are separated in in those versions and the second cards fans do not spin up.

For those with the secondary card SLI fan issue, I am not able to reproduce this here. Is it when you set a manual fanspeed the secondary card will not set the speed as well?

I'm currently back to using 5.3.8 but my experience with 5.3.9, 5.3.9.1, and 5.3.10 were slightly different than the other posts in the thread.
 
All three newer Precision X versions installed without problems. All three required that both primary and secondary SLI cards needed to specify separate fan profiles with the "enable automatic fan control" checkboxes checked for both separate custom fan profiles. The fans for both cards in SLI mode spun up as set in the custom fan profiles and worked as expected.
 
EDIT: After setting the custom fan profile for the first card, I then used the Precision X front panel GPU SELECT in the lower right-hand corner to switch to the second card. I was then able to set the custom fan profile for the second card.
 
The problem was that if I closed Precision X or if I rebooted the system, the custom fan profiles for both cards were lost and I would have to start all over again to specify a custom fan profile for both cards.
 
This problem does not occur in 5.3.8 - I only need specify a single custom fan profile and 5.3.8 will control both cards' fans in SLI mode and remember this custom setting if Precision X is closed or Windows is restarted.
 
I do start up Precision X manually in administrator mode in my normal Windows 10 user account (not as admin).

This is what I am running into as well with SLI.  Needing to set separate fan curves.  I never had to do that before.  When I do set the curves and reboot the system, it seems like only one of the cards fans spin up according to its curve.  If I open Precision and then click on the card in the list that was not spinning, the fans kicked in according to the curve.  I can't say that it forgot the curves entirely like the poster above me, but yes, there is definitely an issue when it comes to SLI and fan control in 5.3.9, 5.3.9.1 and 5.3.10.

Have you guys been able to reproduce the issue?  Do you need any more information from us SLI users?

I solved this problem by doing this: I select the gpu 1, set the fan curve and pressed the "OK" button. Then, I select the gpu 2, set the fan curve and pressed the "OK" button again. In this way, the profile is saved and not unconfigures. (the cards are not linked).

Are the two fan profiles you made still saved if you close (not minimize) Precision X and then re-start the application again, or do you have to set them both all over again?

In Windows 10 when I launch this version I get this problem:

This software only works in the EVGA GPU, and works well in other manufacturers

Precision X works with any Nvidia gpu, but will not work with AMD/ATI gpu's. Was that your question?

Yes, the two fan profiles still saved after doing that, or rebotting the system.

Hi guys, got a very annpying issue here. I can only set the pixel clock higher than default when my second screen is turned off.  In dual monitor mode windows 10x64 the evga tool just switches back to 60 hz. It doesnt store the 80hz setting. Only in single mo itor mode.  Any suggestions?

Hi everyone,
 
I installed a Titan X today.  Is it normal behavior for Precision X 16 to be unresponsive and incredibly laggy when a game is running?  I can barely drag it around the screen or actually use the software when a game is running.
 
With my old Titan I stuck with 4.2.1 because of this issue, but not sure what to use now.

Hi,
 
Thanks for your reply Scarlet-Tech.
 
I tried Afterburner and it seems to be working well.  They must be laughing over at MSI.  So much free advertising to their competitor's customers.
 
Hopefully in the future Precision will become usable for me.
 

Both this and my previous version which I think was 5.3.9 or 8 not sure no longer limit frame rates in Warframe.  I get the feeling that it's the game, though this didn't happen upon a single update(to either version).  I hope it gets fixed as I prefer to limit my FPS and keep my GPU(GTX770 SC ACX) from going overdrive for frames I won't see...and of course prefer not to turn vsync on.  I also use it to keep temps down, and in turn my PC quiet.
 
Edit: Scratch that, FPS limiting doesn't work in Grid Autosport either...so I'm thinking it may be all games.
