So i'm considering overclocking my gpu for the first time. I've never overclokced anything before so i need some help. I'm running Windows 8.1, intel core i5 4670k, asus sabertooth z87, corsair hx 750w psu and most imprtantly a Sapphire radeon hd 7970 OC edition Graphics card.

The first thing I'm wondering is if I can overclock the card even though it's an OC edition? The second thing I'm wondering is can I use msi afterburner on this card, and if not what software should I use? The Third thing is how do I know how much of my psu wattage is being used? Can I use amd overdrive which is implemented in the amd catalyst drivers? What is trixx? Are there any important Things I need to remember? Is it just slowly bumping up the clock speeds until I see artifacting and stuff? Is there anything important I have to do diferently for the core clock and the memory clock? What does the core clock and memory do diferently, and what does each of them affect? Should I leave amd overdrive enabled?

I have the free Version of the unigine vally benchmark program and I've benchmarked my card sometime before With this (I can't remember the score of the top of my head). Can I use unigine valley bechmark before and after overclocking to check for performance boost or should I do something else?

Thanks in advance :) 


EDIT - Some questions: How much of a boost do you normaly get from overclocking Your card? How much do I have to overclock it to get a significant boost in performance? Should I overclock it to just below where It becomes unstable or should i have a little more room between the clock speed and that point? How hot can my card get from overclocking and what should be the max temp?

Maybe an extra 100 MHz if lucky. Like u said BC its the OC edition its already probably pushed pretty far. Do 25 MHz bumps at a time. Do core and memory seperately as to control variables. Yea you can use MSI afterburner or Asus GPU tweak or AMD over drive. I choose asus for my OC. I'd start to worry about longevity when you hit 80/90 C.

Okay thanks i'll try With afterburner

Yeah, you can use MSI Afterburner on any video card, and it is one of the gold standards along with EVGA's PrecisionX. You can overclock your card but it won't be by a lot. I did it with my already-OC'ed card and got an extra 50-100 megahertz I believe. I would recommend having GPU-Z running as a second check to ensure your card speed is actually increasing as you OC.

You basically bump up the clock speed (don't mess with the memory speed) in relatively small increments until you see artifacting or things crash, then you back it off a bit. If you want to be aggressive you then up the voltage a bit, and keep upping the clock speed until you find the highest stable speed and voltage that your card can support. If you start upping the voltage though it's increasingly likely you will reduce the life of your components. The benchmark I'd recommend is Unigine's Heaven, and crank all the settings up. Don't worry about your PSU having probs unless you are already on the border of having probs with it supporting your system.

What overclocking tool do you recomend for a New user that's easy to understand? At this time i've hear that trixx and afterburner are the best Tools.

I use afterburner and its easy to use, just simpily launch it and ajust the slider, apply and save the profile and your done.

Start with increments of 25mhz, then go 50mhz, 75mhz etc. I use PrecisonX over AB due to Afterburner not having K-boost or overvoltage settings, it has been confirmed by(Unwinder himself) that the overvoltage settings do not take effect using Afterburner..

I've used Afterburner, it's pretty simple and it works.

I've just overclocked myt Graphics card using msi afterburner and I got a small, but noticeable performance boost. Thanks guys :)
