To try out overclocking we used the Performance Tuning capabilities that are built into AMD’s Adrenaline Edition drivers. We did a very simple manual overclock that left the GPU voltage untouched and we maxed out the power level to +15%.
We knew that the memory would overclock to the highest limit from our cryptocurrency mining, so we raised it from 2000 MHz to 2150 MHz and and had no stability issues. We enabled fast memory timings to further optimize the memory performance.
For the GPU core clock we had to slowly increase it to find the highest stable setting. Our 6700 XT sample seemed to be happy at 2750MHz for the maximum clock frequency. 2800 MHz would crash the desktop and anything between 2760 and 2790 was fairly unstable.
This overclock gave us an overall score of 12,366 points in 3DMark Time Spy and a GPU score of 12,061. At stock speeds we got 11,741 overall and 11,354 for the GPU. This overclock allowed us to improve our 3DMark Time Spy score by over 5%.
The monitoring utility in 3DMark showed that we were hitting speeds of up to 2640 MHz by setting the max frequency to 2750 MHz. The clock was typically running between 2528 MHz and 2640 MHz with this overclock on this application.
This is a solid overclock and we are happy with the results as it moved the Radeon RX 6700 XT ahead of GeForce RTX 3060 Ti cards in our chart!
Let’s wrap this up!
