Overclocking
The ASUS GPUTweak Software provides two new and useful features.
First, you now get a temperature heat map, similar to what EVGA pioneered with iCX. ASUS has placed four additional thermal sensors near the memory and VRM, which gives you a better feel for temperatures.
With "PowerDetector+" you can measure actual power flowing through each of the pins of the 16-pin power cable. This makes it easy to detect faults. Please note that when running at maximum power limit, there might be false positives. The cutoff is set to 9.2 A, which can be triggered sometimes when running at 600 W.
Testing notes & interpretation- Overclocking results listed in this section are achieved with the default fan, power, and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for most users.
- Each GPU, including each GPU of the same make and model, will overclock slightly differently based on random production variances.
- The data in this table shows comparable overclocks using identical conditions from previous TechPowerUp reviews.
- The Average GPU clock frequency reported in the table is an actual measurement of the clock speeds during 3DMark Time Spy Extreme GT1. Making a "maximum overclock" comparison just based on the "rated" clocks in GPU-Z will be inaccurate—actual frequencies is what matters.
Using these clock frequencies, we ran a quick test of 3DMark Time Spy GT1 to evaluate the gains from overclocking.
- The hand-overclocked RTX 4090 FE achieves 126.9 FPS in the same test.
- I also did a run at maximum voltage ("+100" in GPUTweak), which increases actual voltage from 1.045 V -> 1.070 V (i.e. very little, +2.4%). Clocks and performance went up a little bit further, to 3090 MHz on average and 138.2 FPS
- Increasing the power limit doesn't gain any performance increase, the default of 500 W is high enough
Power Limits
All NVIDIA graphics cards have a power limit defined in the BIOS, which limits power draw by adjusting Boost frequencies accordingly. A second limit exists that defines the maximum TDP adjustment limit for user overclocking; i.e., how far the power slider will go. In the second chart, the (+xx%) value lists the percentage increase from the tested card's default power limit to the highest available manual setting—the slider's adjustment range.
