It brings up a pixel clock slider that automatically sets your refresh rate for you. No patches, CRU, or even a restart, required for me. Automatically sets the refresh rate in nvidia control panel and in your display control panel (right click+screen resolution+adv settings).
Again, this could be common knowledge by now so I'm sorry if I'm all excited over here for something that everyone knows about already lol. I couldn't go past 96 hz without a faint slightly transparent red smear/line about a half inch wide showing up on the right side of the monitor. So I just keep it at 92 hz.
Without using the toasyX Clock Patchers that modifies the NVIDIA video driver to remove the 330 MHz pixel clock limit for dual-link DVI and the 400 MHz limit for SLI ..And the AMD Clock Patcher that modifies the AMD/ATI video driver to remove the 330 MHz pixel clock limit for dual-link DVI...Without using ToasyX patches anything over About 96hz not be working as i don't not believe EVGA precision patches the Nvidia or AMD drivers pixel clock limits!...and without this you simply will not get much higher than about 96hz....NVCP may report your higher refresh rates are working as in the picture below..yt windows will not
will not be seeing your higher custom without using using toasyx patches!
Also in picture you can clearly see that NVCP is reporting 120hz however windows can not see it!..that picture was taken when i was using CRU to create my Custom refresh rates and attempting to keep Nvidia Geforce expereance installed!...However CRU uses EDID overrides that conflict with Nvidia Geforce expereance so you ether have to uninsatll Nvidia Geforce expereance or import the blank-extension.dat into CRU at the time of creating your Custom resolutions if you are using Nvidia! ...also its worth nothing that the below picture was taken using CRU with the blank-extension.dat imported into CRU!... However the blank-extension.dat is far from a perfect fix attempting to keep Nvidia Geforce expereance install while using CRU EDID overrides which still results in windows on many many occasions simply refusing to see your custom resolutions...which is why we now use a monitor driver using Nvidia cards which allows using NVCP to create our custom resolutions and them to be seen by windows and therefore in games without any conflicts what so ever!
I believe what you see in the picture below with NVCP reporting 120hz yet windows not
being able to see it!... which means that neither will your games!... will be happening to you using EVGA precision with no driver patch...if you have set a 120hz profile in EVGA precision open up a game and turn Vsync on in game graphic settings use the lowest detail settings in the game so you are able to hit high FPS... now if your game reports 120 fps it is all workng fine!...however without patching the drivers which i am sure EVGA precision does not do then you will never hit 120FPS in any game using Vsync becaurse your custom resolutions without driver patches are simply not working.
Edit :However i would be very interested if it did in fact patch the drivers correctly as it would be another option for us all..i am going to do some research now on EVGA precision..thanks for the info
Edit 2:- I have found a post from Toasyx and now believe i was right and it does not work at least for SLI users and it seems it only works at lower refresh rates as i thought...ToasyX post below concerning the use of EVGA precision...it seems it only is using the regular patch and your refresh rates will indeed be capped at around 96hz if your using SLI...will do some more reading about though
More info here!
Quote from Toasyx on EVGA precision below:-
The patch is still needed in three cases:
1. SLI needs the full patch to work properly beyond 400 MHz pixel clock.
2. Some 500-series cards are limited to 400 MHz without the full patch. 600-series and newer cards are not limited.
3. CRU needs the regular patch to add resolutions beyond 330 MHz pixel clock. The regular patch won't break HDCP.
600-series and newer cards without SLI don't need the patch when using the NVIDIA control panel or the EVGA pixel clock feature.
Edit 3:- Another quote from that forum below
"So I got my Tempest in just a few hours ago and the first thing I did was try this utility to see what it could do. I have found that it looks like it let you go to 120 +, but in reality it caps at 96hz. even when I select 120 or 128 (129 is where my panel starts to flicker) it says it is pushing a 480+ MHz pixel clock, but if I toggle the selected display to my old monitor and back, it shows 96Hz framerate at a 390MHz pixel clock. Off to try Toasty's now!"Edited by lawson67 - 3/12/14 at 6:41am
