Overclocking
Overclocking the Radeon RX 7600 isn't as complex as on the RX 7900 Series, but it's still not trivial.
- First of all, you have to raise the power limit to maximum, the slider ends at +12%, which is a bit lower than on most other Radeon cards, which go up to 15%.
- Next, max out the memory clock slider, it's rather short, too, topping out at 2400 MHz—no doubt the memory can go faster than that.
- Now, also increase "Max Frequency" to maximum, which is only 3000 MHz, or a meager +3%. Not sure why AMD felt they had to limit the card so much.
- At this point run a first stability test and record performance.
- Now gradually lower the maximum voltage (default is 1.2 V), until your card becomes unstable, which happened for me at 1.025 V.
- Done, that's all you can do on the RX 7600.
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 3DMark Time Spy GT1 to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 8.7%.
