Overclocking
Memory overclocking was held back as the card would crash immediately when I set anything above 1675 MHz. At 1675 MHz, the card will run stable all day. Such a "wall" is usually an indicator that something is wrong with the memory settings in the VBIOS. It's possible that Gainward or NVIDIA didn't account for the fact that these chips are Hynix and not Micron—they require slightly different timings, especially at higher clocks.
* These results were tested in 2020, on a Core i9-9900K. The numbers should be close enough though and I feel they're adding more context here.
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.
Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 11.8%.
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.
