Title: Anyone here knows anything about overclocking?
Post by: Prox on August 23, 2013, 02:11:48 AM
   With my new graphics card there was also included a program for adjusting it's settings such as overcloacking, fan speed and maybe some other things. I have previously red about dangers of not properly overcloacking your gpu but seeing as this program appears to be specifically made for my gpu I may or may not try overcloacking it someday. I'd also like to know something about changing the fan speed: what's it's benefits and what could possibly go wrong.

Graphics cards are rated at specific speeds certified by the manufacturer, which means they will still acknowledge your warranty and replace/fix your card if something went wrong with it.

This is why some people choose to buy cards with manufacturer overclocks, you can get the faster speeds and still have a valid warranty.

This is where you might start looking, choose some "superclocked" model of your card to see what speeds it can run at.

Know that all cards are different and will handle speeds and achieve stability with different settings.

The key to overclocking is achieving a faster speed while maintaining stability.

Stability boils down to reliability of the card under load.

For example, lets say you raise the core clock (man gpu speed) by 100 megahertz and windows runs fine. Unfortunately you start up a benchmarking tool or some intensive game like Battlefield 3 and your system BSODs or freezes. That would be an unstable overclock.

Next step after searching card overclocks similar to yours, use google and search your card model and overclocking it. You'll most likely find either blogs or forums that are discussing potential overclocks and performance configurations for your card.

Most overclocking boils down to a few tasks including:

1. Raise clockspeed
2. Test stability with benchmark/stability tester/intensive games of choice
3. Unstable? Try raising voltage or changing clocks
4. Check temperatures after some time, still within manufacturer recommended ranges?
5. Too hot, reduce voltage and experiment with different clocks
6. Failsafe, restore default clocks and voltages (make sure to keep track of which ones you have used and their success rates)
7. Cool and stable over time? Continue overclocking if desired
8. Some higher clocks may work better or worse when other parts of the card (memory) are also overclocked - experiment
9. Just make sure not to overvoltage (go outside manufacturer ratings) for too long or far --same with temp

//btw corrected spelling in your thread title "overcloaking" -> "overclocking"

I like using EVGA Precision X and MSI Afterburner for OCing, but it's mainly personal preference.

About the fan speed, the default settings usually try cooling the GPU while keeping it quiet, so it changes according to the load. If you care less about the noise and want your GPU to stay cooler then you should set your own fan curve (if you have that option in the program). Setting it to a certain speed won't be a good idea, since it might get very hot and then the fans won't be able to change to a higher speed to cool it down.

OCing is very easy once you try it once and on the GPU it's easier than on the CPU.

to get a good idea of what to OC to google for "<Your gpu> overclock" and some threads should come up with some clocks to try out :)
