Overclocking GPU (PNY 750 Ti) Need assistance! :D
Overclocking GPU (PNY 750 Ti) Need assistance! :D
Purchased my PNY 750 Ti OC XLR8 last December and am satisfied with its performance so far, but I need to overclock it. I’m ready to begin, though I still require some guidance as this is my first attempt at overclocking. What software should I use? Do anyone have experience with the 750 Ti or this specific PNY OC XLR8 model?
Well, I've experienced the most success when using a tool named MSI Afterburner. The main reason I haven't managed to overclock an Nvidia card before is that every Nvidia card I've had has failed to do so... but this one seems to have the potential to work.
First things first, though... grab MSI Afterburner.

The page under the banner offers three sections... click the Downloads tab and select the standard "MSI Afterburner" file.
Once installation is complete and everything is set up (RivaTuner can be installed next as an extension), you'll need to prepare your system for the next steps.
Well, I've had the best luck overclocking with the use of a program called MSI Afterburner. The only reason I haven't been able to overclock an Nvidia card before is because every Nvidia card I've ever owned has been incapable of overclocking...however, this one SHOULD be capable of doing so hopefully.
First off, however...go get MSI Afterburner.

The information page under the banner has three tabs...click the Downloads one and click on the normal "MSI Afterburner" download.
After you've gone through with installation and everything (RivaTuner can be safely installed alongside it as it's an extension of MSI Afterburner), you will want to do these things firing up the computer for the first time.
Step 1: Look at the sliders that the program gives you right away. If there is no Power Limit slider, your graphics card may be voltage locked, in which case it's not safe or possible to do an overclock unless you are an advanced user. However, if there IS a Power Limit slider, set it all the way to 20% positive (this way >>>>) for the purposes of testing to see if you can overclock.
Step 2: Once you've done that, look around for the "Apply At Startup" or "Apply Overclocking At Startup" tickbox. For now, shut this off. This will ensure that the system will still boot with the original settings if the overclocking fails.
Step 3: Look at the Core Clock and Memory Clock sliders. There are numbers beside them...you should be able to click on these numbers and type in values for each one. For the purpose of this test, add 10 to the Core Clock and Memory Clock numbers and hit the enter key on each one. This will not apply the overclock just yet.
Step 4: After that, make sure you don't have anything else important currently running, and click on the Apply button. The computer should idle for a full 60 seconds (one minute) with no artifacting or unusual system behaviour. If the Nvidia card is a non-overclockable card, the system will crash immediately, in which you can safely start the computer back up and uninstall MSI Afterburner, or go tinkering further to see if you can adjust the settings to allow graphics card overclocking on your system. If it works, go ahead and try a game for about a half hour to see if the card stays stable.
Step 5: If you want to get more performance out of the graphics card afterwards and the computer isn't doing anything unusual, you can make a custom fan curve in Options, Fan tab and "Enable User Defined Fan Control" tickbox. If there are two yellow dotted lines, those are the limits of the GPU fan. I recommend setting the fan curve line with the moveable dots so the fan runs as fast as possible at 70 degrees celcius, or you can adjust the fan to run as fast as you would like.
Step 6: If you have decided to adjust the fan curve in the previous step for more performance, you can repeat Steps 3 and 4, upping the MHz of Core Clock and Memory Clock by 10 each time until the video card starts experiencing stability issues. When it does, reduce both values by 10 once you restart the computer and then recheck the "Apply on Startup" tickbox. You may adjust the Fan Curve setting in the Options as much as you like if necessary depending on the GPU temperature...the GPU will start becoming slowly damaged if the GPU exceeds 80 degrees celcius.
Bonus Step: To get a temperature display in the Taskbar Icons section, you can go to Options>Monitoring>Select GPU Temperature in the Active Monitoring Hardware Graphs List>Click the "Show in tray icon" tickbox in the bottom of the GPU temperature graph properties.
I hope this helped you out some. If you feel uncomfortable at any step or are experiencing difficulty at any step, feel free to ask questions and even submit screenshots.
