I'm using the Qnix 2710 matte monitor and until recently have only been using it with a single GTX 780. I just installed another 780 though 2 days ago. Up until then I wasn't using the full patch, and even with the new SLI setup I still don't think I need to use the full patch if I'm not going over the 400mhz pixel clock limit, AND Toasty also mentioned Titan and 780 users wouldn't need the full patch for SLI. Is that true? So far I've only been able to get my Qnix to 93 hz, anything higher than that some weird faint discoloration appears on the screen (its like a vertical band but very patchy).
#1. 93hz is around 374mhz on the pixel clock which is still below 400, so should i just stick with the partial patch or go with the full?
#2. What's the difference in the CRU app provided here, from the one provided by windows? (right click desktop, screen resolution, advanced settings, create custom resolution)
#3. For awhile I couldn't get the refresh rate created in CRU to show up in my control panel resolutions, presumably due to GeForce Experience being installed. Instead of uninstalling GeForce Exp or importing that blank.dat file he mentioned, I found a tool in EVGA Precision X that lets you create a custom refresh rate by adjusting the Pixel Clock via a slider. I just raised it to 93 hz and applied the setting and voila! It shows up in nvidia control panel and the windows resolution menu, as well as in game. The refresh rate tester website he provided also verified the screen was running at 93 hz. Has anyone else used this instead of the CRU? Is it legit?
#4. Is there anything I can do to get it higher than 93 hz without that weird discoloration? I was just wondering if I did use the CRU app and maybe adjusted the values in there (which I have no idea at all what they mean, e.g. front porch, back porch, blanking, etc) if it would allow a successful higher refresh rate. And if I do use the CRU app do I need to match the pixel clock value in there with the pixel clock slider bar in Precision X? Will one override the other?
Thanks for any help. Its just all a bit complicated for my brain
1) Since you are now SLI (780's) I'd go with the Full Patch ... that's the reason we go SLI is for higher frame rates to hopefully match higher refresh rates like 96-120Hz ... right
2) None, CRU is not needed for Nvidia setups, all custom refresh rates are done through the NVCP! KIS(S)
Note: You can use the windows display app to double check your settings are being applied.
3) Don't use CRU or Evga's programs for custom refresh rates, it's simpler and more accurate through NVCP.
Note: I tried Precision X for awhile but the settings were always a bit "off" from what Windows/NVCP were reporting
4) For more info check out my posts [HERE]
and my referrals to Toasty's comments on weather the Full Patch is needed for SLI780GTX's [HERE]
bottom/end of my post. No one I know of yet has confirmed Nvidia SLI works without the Full Patch for higher OC's?
Also realize most people will need to tighten their timings for 110Hz+ , but see how far you can get with stock timing's 1st, so you don't get the annoying effect of your gpu ram not properly downclocking @ the desktop with "most" tightened timings!
To get to 120Hz you may have to tighten them a bit as in the example below ...
Or check out Lawson's new timing's [HERE]
for a 110Hz WITH proper gpu ram downclocking @ desktop
Check back let us know how it worked out Edited by TomcatV - 5/16/14 at 1:17pm
