![]() ![]() Drop back 10MHz from the last used setting using the slider.If your system passes, increase the frequency by 10MHz on the slider again.Either move the slider for the GPU to up by 10MHz using the mouse, the keyboard arrow keys, or directly key in a value 10MHz higher. The offset value will tell you how far from stock MHz it's been changed.The next thing we are going to do is see what our maximum GPU frequency is. It is actually unlikely that we will achieve this frequency when the GPU core is overclocked as well (due to reasons such as EMI, power draw, and induced heat from the GPU affecting the GDDR5 chips and PCB tracing, but what we do have is a known range within which we can work. We now have the stand alone maximum memory frequency for our graphics card. We are not going to change any voltages in this basic guide until the very end. If passed successfully stop there and record the frequency that your system passed the benchmark test successfully at.Drop back 100MHz from the last used setting using the slider.Repeat until your system fails the benchmark test or crashes.If your system passes, increase the frequency by 100MHz on the slider again.Open FurMark and run the benchmark preset that you prefer.The offset value will tell you how far from stock MHz it's been changed. Either move the slider for the memory to up by 100MHz using the mouse, the keyboard arrow keys, or directly key in a value 100MHz higher.The first thing to do is see what the maximum memory frequency is. Once we have these temperature numbers and are confident that the card is running perfectly at stock speeds, then we can overclock! First: Memory Overclocking You can use any of the pre-set profiles too, as long as you are using the same settings each time we do a stability test. Remember the point of this exercise is to establish knowledge of the baseline stability of your graphic card at stock speeds. ![]() Open your FurMark stress test - Select the profile you wish to run, I suggest you use the profile that will match as close to your gaming resolution. This way we can check the history and then make informed calls on the correct way forward. Why do we want this? Well if the overclock fails it is handy to look at the logged file and see what the possible cause of the failure was, as if your system freezes up you cannot check what you’re GPU temperatures were when the system froze. You will be prompted to select a default location for the log file it will be creating. Select the sensor tab, look at the bottom and tick both the boxes. Open which ever version of GPU-Z you are using. That’s why FurMark is often used by overclockers and graphics cards fanatics to validate an overclocking, to test a new VGA cooler or to check the max power consumption of a video card. It makes it possible to push the GPU to the max in order to test the stability of the graphics card (and the PSU too!) leading to maximum GPU and VRM temperatures. What is FurMark?įurMark is an OpenGL-based GPU stress test utility (also called GPU burn-in test). GPU Tweak allows you to optimize clock speeds, voltage and fan speeds on up to four graphics cards independently or simultaneously, you can also select between GPU Tweak’s Standard or Advanced modes depending on your level of experience.Ī good stress test to push your overclock stability is FurMark, while GPU-Z is a must and is included with the ASUS GPU Tweak however you can also download the latest version separately as an ROG Skinned GPU-Z. For CrossFireX setups also download the latest version of CAP. Downloads you will need:įirst of all download the latest version of ASUS GPU Tweak and AMD Catalyst drivers to get support for the latest models. While these cards fill the news and people's upgrade anticipations right now, you don't need PCI-Express 3.0 or even the latest series of graphics cards to overclock though - generally speaking any graphics card can be overclocked in some way. This guide explains the process of how to overclock your graphics card with GPU Tweak, and applies to Nvidia and AMD graphics cards alike. New PCI-Express 3 cards have hit the market and include the Nvidia GeForce GTX 600 series, such as the recent GTX 680, and AMD's Radeon HD 7000 Series, including ASUS designed cards such as the Radeon HD 7970 DirectCU II, 7950 DirectCU II and 7870 DirectCU II as well as their TOP pre-overclocked variants. 2012 is an exciting time to need a graphic card upgrade. ![]()
