We used the indispensable Unigine Heaven along with 3DMark's well known Fire Strike and Time Spy benchmarks to cover synthetic testing along with a host of real-world gaming counterparts. Our performance analysis articles on recent games can provide additional insight into what performance you should expect. Try to pick real-world benchmarks that use engines relevant to the games you like to play.
One synthetic and one or two real-world benchmarks should be plenty. Find a few reliable, easy to use gaming benchmarks to run before, during, and after overclocking, both for stability testing and performance measurement purposes. Now it's time to test the hardware and see how well your card currently performs.
In the unlikely event you do need a new, higher-rated PSU, take comfort in the fact that you'd be doing this for almost any serious upgrade or CPU overclock. Overclocked hardware pulls power beyond normal design specifications and if you're just squeaking by with 100 watts to spare, you'll need to upgrade to handle the additional load or risk hard-to-pinpoint stability problems.īut recent hardware generations have largely grown more power efficient, so anything but the bare minimum PSU is likely to give you plenty of headroom for an overclock. While the case is open, it's also wise to check and make sure the current power supply is up to the task ahead. If you opt to remove the card for a full clean-up and overhaul, don't forget to release the locking tab at the forward edge of the slot that secures the card to the motherboard. If the card itself has gotten dusty, carefully blow it clean with a can of compressed air.
Make sure cables are routed clear of fans and don't obstruct case airflow. If you're looking to overclock a card you've already installed, then it's probably time to crack the case and clean up in there. It's all being made possible by Razer, which stepped up to support this months-long project.
PC Gamer is going back to the basics with a series of guides, how-tos, and deep dives into PC gaming's core concepts that we're calling The Complete Guide to PC Gaming.
