Overclocking Results


NVIDIA claims thereís a good amount of overclocking headroom built into the GTX 960 and their default frequencies are quite conservative. ASUS has partially taken advantage of this my launching their card with an included ďOC ModeĒ that automatically increases the STRIX OCís Boost frequency to around 1317MHz. They also have a Silent button in their GPU Tweak utility that lowers clock speeds and keep the fans in a suspended mode in many applications. Weíve already seen that excess thermal headroom allows this card to go even further on its own (to about 1416MHz) so what does that mean for actual overclocking?

Before we discuss the actual frequencies we achieved, letís talk about limitations. According to NVIDIA, their board partners have the ability to build whatever Power Limit they want into these cards provided the core is provided with enough input power and it detects sufficient PWM capacity. ASUS has taken a slightly conservative approach by limiting their card to 15% of additional Power Limit headroom which isnít all that bad. Voltage meanwhile is capped at a maximum of +50mV, that that is what ended up providing a ceiling for our overclocking aspirations.


So, with the GPU voltage set to 1.213V and the Power Limit pushing 115% we set out to see what the GTX 960 STRIX OC had left in its tank. It turns out, there was quite a bit.

We were able to achieve another 92MHz of Boost which equated to the core running at a staggering constant 1510MHz while the memory plateaued at 7776MHz. The core frequency itself is extremely impressive when you consider a reference GTX 960 operates at a Boost speed of 1178Mhz but the memory was simply par for the course. With that being said, the amount of extra performance you can eke out of this card (or at least this sample) can be put to good use towards minimizing its limitations but in bandwidth-limited titles like Shadow of Mordor, expect limited real-world returns.
