How to overclock a graphics card

When someone mentions the word “overclocking” we instinctively start thinking about a processor and how high we can ramp the bus speed and multiplier up to give the best possible speed. This of course gives you better value for money as you’ll end up having a product that goes faster than what you paid for. Result!

Processors aren’t the only thing that can be overclocked though. There’s memory and of course graphics cards, but for some reason graphics or video cards don’t get much attention when it comes to overclocking and we have a theory as to why. Processors, for instance, are generally aimed at a market which lets people purchase them and do as they please whereas graphics cards have more specific models aimed at pre-overclocking and super-overclocked editions and turbo models and so forth. This takes the fun and enjoyment away from the user and even these ramped up pre-overclocked cards generally still have a bit more juice left in them to unleash by the user.

There are several ways to overclock a graphics card and we aim to focus on the main one that we use for our reviews and graphics card testing. Of course you can flash your BIOS or download many different software utilities but when it comes to it, they are all much of a muchness, so who knows best?

Personally, we think that we know best. Not us specifically but review sites in general as we review the hardware that you’re confronted with day in and day out. The likes of a graphics card goes through some of the most rigorous testing you can think of including us pushing the limits of the card’s core clock and memory clock speeds.

So as we mentioned, many different applications can be used to do this, so what’s the difference? We’ve tested many graphics cards over our time, and with this comes experience of the products and the utilities that we use. Our tried and tested methods leave us with a select handful of applications that we know, trust and give us fantastic results every time.
