Overclocking

(the correct ROP count is 160, this is a bug in GPU-Z that will be fixed in next release)

Overclocking the Radeon RX 7900 GRE is very similar to the other RX 7900 Series cards.

• To start, you have to raise the power limit to maximum, the slider ends at +15%
• Next, max out the memory clock slider, it's rather short, topping out at 2316 MHz, definitely not high enough to use the full potential of the memory chips.
• Now, also increase "Max Frequency" to maximum, which is at 2803 MHz, not much higher than the default of 2530 MHz, another artificial limitation
• At this point run a first stability test and record performance.
• Now gradually lower the maximum voltage (default is 1.05 V), until your card becomes unstable, which happened for me at 0.89 V to 1.02 V, depending on the card.
• Increasing the Min Frequency slider made no significant difference in performance. This might increase power consumption though for very little actual FPS improvement.

Overclocked Performance

Using these clock frequencies, we ran a quick test of 3DMark Time Spy GT1 to evaluate the gains from overclocking.
