Overclocking
Overclocking the Radeon RX 7600 XT is very similar to the RX 7600. It's not 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 +20%, which is a bit more than on most other Radeon cards, which go up to 15%.
- Next, max out the memory clock slider, it's rather short, topping out at 2500 MHz, which is 100 MHz higher than the RX 7600, but still not high enough.
- Now, also increase "Max Frequency" to maximum, which is at 3200 MHz.
- 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 1.05 V to 1.10 V, depending on the card.
- At this point I also pushed up the Min Frequency slider, which seems to have helped a little bit gaining some additional performance. This might increase power consumption though for very little actual FPS improvement.
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.
