Overclocking, Power & Temps
At idle, Zotac’s RTX 2070 Amp Extreme idles at 300MHz. The fans sit at around 29% or 1025 RPM which lets the temperature stay under 30C. Total system power draw runs around 105W from the wall.
Under load at stock, we see the card spike to as high as 2100MHz but falls to around 1965MHz as it heats up. Power draw at this point hovers around 330W from the wall which gives us about 225W of additional power draw from the GPU alone, right on par with its rated TDP.
We’ll ramp the fan to 100% as well as max out the power limit to 110% next.
We tried the OC scanner feature first.
It slowly ramps up to almost 2100MHz before finishing.
It gives us a boost of 60MHz supposedly.
Interestingly, this seems to hurt our scores more than help. Our ‘stock’ Timespy ran came in at 9245. We’ll move on manually from here.
After resetting to defaults and again setting the power target to 110%, we were able to slowly raise the memory speed up to +750MHz for an effective speed of just over 15.5 GHz. This makes our score jump pretty nicely.
We push the GPU core speed to +40 MHz with the memory still at +750 MHz and get nearly 9700 points out of Timespy, ‘only’ a 5% increase but the Amp Extreme starts out well ahead of all of our other RTX 2070 cards.
