After seeing the NVIDIA live presentations and the hype regarding clock speeds hitting ‘at least 2.1Ghz’, we were very keen to see how far the Asus ROG Strix GeForce GTX 1080 would go.
Asus offer a tool called called Asus GPU Tweak II which has a range of presets and charts right out of the box to help you on your overclocking journey:
We clicked on Professional Mode to gain granular access to the controls and began playing.
First we decided to discover what the card’s maximum core clock speed would reach to. We increased the GPU voltage to 100% and the power target to 120% to give ourselves the maximum headroom we could. Next, we applied a very modest +14MHz on the boost clock to take it to 1950MHz in the tool (but strangely this actually translated to 2050Mhz in operation). Next we fired up MSI Kombuster to run a stability test…
However, we were quickly disappointed to find that the Asus ROG Strix GeForce GTX 1080 began to crash when even the most modest boost clock was added; it appears that Asus have the card right at the limit of stability already:
Disappointed but undeterred, we proceeded to see how much the memory would overclock.
Fortunately this area of the card was significantly better and we managed to get a +1000Mhz (+10%) overclock out of the Crucial GDDR5X memory to total 11000Mhz – very impressive:
Overall, our results were as follows:
- GeForce GTX 1080 Founder’s Edition – Base Clock 1607Mhz, Boost Clock, 1733Mhz, Memory Clock 10000Mhz
- Asus ROG Strix GeForce GTX 1080 – Base Clock 1784Mhz, Boost Clock 1936Mhz, Memory Clock 10000Mhz
- Asus ROG Strix GeForce GTX 1080 (Overclocked) – Base Clock 1784Mhz, Boost Clock 1936Mhz, Memory Clock 11000Mhz
We re-tested two game benchmarks below to check the difference:
Whilst not earth shattering, the just over 2% performance improvement is impressive from a simple memory overclock alone.
