Overclocking
Overclocking is pretty complicated, just like on other RDNA 3 cards. Just adjusting the clock frequencies will have no significant performance impact.
- First of all, you should raise the power limit to the maximum of +15%, to make sure that's out of the way.
- Next, set the maximum clock range to the maximum of 5000, so that doesn't limit us either.
- Now set the minimum clock to 2800 (don't set it too high or the card will crash). If later on you notice that clocks during testing seem stuck around that mark, you can raise it further to 3000 and 3200. This really doesn't set actual minimum clock, but rather acts as some sort of guidance for AMD's clocking algorithm.
- From here on slowly reduce maximum voltage until your card becomes unstable running benchmarks or games. Undervolting is a must for RDNA 3, because that will free up some power headroom for the clock algorithm to push frequencies higher. These cards typically get unstable around 950 mV, so there's a lot of headroom (the default is 1.15 V).
- Once that is finished, bump up the voltage by 50 mV (to ensure there's no GPU clock instability). Now set memory to 2600 MHz and work your way up in steps of 10 or 20 MHz. When running stability testing the memory will just crash at some point, there's no artifacts or slowdowns.
- With maximum memory figured out, restore your undervolt and start playing games
- If you notice any instability, increase voltage by 10 mV, or lower memory OC a little bit. No need to touch the clock sliders.
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.
