Once that is done we need to seek the maximum for the memory, increase the clock frequency, typically one the memory frequency hits its maximum you'll spot little dots or small artifacts on your furmark screen. This is roughly what you should have in your screen during the overclocking session. Again, increase the clock frequency in small steps, after each incremental clock frequency increase, hit apply. The next on in line is the shader domain, we can gain a lot of performance here. If you system locks up, restart, repeat procedure and drop down ~25 MHz. If you see artifacts either stop Furmark immediately or restart. In Rivatuner increase GPU Core clock in 10 MHz increments. We now start to overclock the core clock first, then the shaders and lastly the memory. You'll now open up the three domains we are tweaking today.

So here's what we need to do, download these two files.Īfter downloading, install Furmark.
