Overclocking the EVGA GTX 1060 SC Gaming Edition ACX 2.0
Overclocking the Pascal GTX 1060s are not as easy as overclocking Maxwell architecture-based cards. We already overclocked the Founders Edition of the GTX 1060 with PrecisionX OC and you can read about methods and our results here.
We learned that experienced overclockers won’t want to bother with the PrecisionX OC scanner at all – except perhaps to rough in a quick overclock as a starting point. The main thing to remember if want as high an overclock as possible is to turn the voltage up to maximum, set the fan profile to “aggressive” or to 100%, and go from there.
You also need to remember that Pascal overclocking is highly temperature dependent. Keep your GPU cool and you will max out your overclock. Adding voltage is secondary – it only moves the limit up a bit – as the GPU’s BIOS controls it automatically, and it is best used to stabilize a marginal overclock.
This is the maximum overclock that we achieved with the GTX 1060 Founders Edition by setting the fan to 100%, turning up the voltage to 100% and cooling our room below 72F:
We achieved a final stable overclock of +225 MHz to the core which settled in at or above 2088MHz with GPU Boost 3.0 for the majority of our benching as we kept our room cool for all of our game benchmarks. . . . Our memory overclock remained at +700MHz for its clock of 4704MHz which greatly contributed to increased performance.
The EVGA GTX 1060 SC’s card’s base clock is 1607MHz, up 101MHz over the reference Founders Edition base clock, and the EVGA boost clock is 1835MHz, 127MHz higher than Nvidia’s guaranteed minimum reference boost of 1708MHz. These are the clocks that we actually observed with our EVGA GTX 1060 SC with out of the box settings after looping Heaven 4.0 for at least one-half hour (Power/Temp Target set to maximum):
As you can see, the Boost 3.0 remains at 1999MHz with stock fan/voltage settings and only Power/Temp targets are at maximum and temperatures rose to a maximum of 65C in a warm room.
As in the screenshot above, we looped Heaven 4.0 continuously with a +100MHz core offset and +750MHz added to the memory. Ultimately, the memory was backed down to 700MHz and the voltage was set to maximum for complete stability, but the fan speed was left on automatic “Aggressive Profile”. Although the temperatures again rose to a maximum of 65C with the voltage set to maximum, the EVGA GTX 1060 SC never throttled in a warm (77F) room, but its core clock remained locked on at a steady 2100MHz and the memory clocks were 4752MHz.
In contrast, the Founders Edition of the GTX 1060 needed a 100% fan profile, a cold room (72F), and maximum voltage to reach the same +700MHz memory offset, but its core could not stay locked at 2100MHz, and it frequently dropped to 2088MHz as it throttled slightly. So the EVGA 1060 SC not only ran cooler with far less fan noise, it overclocked slightly better.

Lets see how the EVGA GTX 1060 SC compares with the Founders Edition, with the RX 480, and with other competing cards of Summer, 2016.
