I looked at Heaven and Valley and some other programs often used for stressing, but the truth was these did not simulate game load well and seemed to produce inaccurate results. Next we need a way to maintain the load for the duration of our testing. However, the feature we want most is the logging, which enables a long-term run of the card I suggest over 60 minutes for accurate information that we can use to see the real results. We begin with GPUz, a program that will allow you to monitor various aspects of your card, specifically the core clock speed. The method for this I have found to work best takes a bit of work, but the results are dead-on accurate. The KEY to a good, meaningful, overclock on the series is not how high you can make the boost clock set, but how high you can get the chip to maintain speeds under load.īefore we start with the tweaking, we need a way to accurately and reliably test our efforts and see what our maintained clock speeds are under gaming load. The result is often the chip running at a lower clock speed under load than what the boost clock is set to. It works to reach this within limits set by the thermal potential of the chip as well as the power limits set on the card. Damage caused by irresponsible overclocking is not covered under warranty, so do anything suggested in this article at your own risk.
