Yes, less voltage supply in combination with the right frequency (MHZ) and whatever doesn’t make the video card too hot, is the solution for more frame rates in games.

I did some tests to get the most performance / fps out of it. I soon found out that minimum voltage in relation to a fixed lower frequency is therefore more important for a gain in performance.

Assuming the use of the standard mechanical cooler on the GPU

Setting all GPU frequency & voltage to the highest is therefore of no use, except for the GPU memory frequency & power limit (%). The GPU eventually overheats and balances at lower frequencies resulting in lower FPS.

Highest possible settings for RX 7600 in AMD Software Adrenalin Edition:

(Not recommended)

GPU Max. Frequency (MHZ): 3000

Voltage (mv): 1200

VRAM Tuning Max. Frequency (MHZ): 2400

Energy limit (%): 12

After some benchmarks in 3DMark, Superposition Benchmark, I achieved the highest possible performance with the RX 7600 at the following settings:

GPU Max. Frequency (MHZ): 2841

Voltage (mv): 1140

VRAM Tuning Max. Frequency (MHZ): 2400

Energy limit (%): 12

All applied settings are stable and extensively tested.

This is quite a large undervolt and a decrease to 2841 MHZ compared to the die hard of 3000 MHZ of course. (for a standard-overclocked RX 7600 from Gigabyte)

Note: 2841 MHZ is the sweetspot for the videocard in combination with this minimum voltage. Most of the time it will be in de 2750’s and 2800’s in games, which is very important for the most fps gain.

!Important: set the memory timing to “Fast timing” this is also beneficial.

Settings used in AMD Software Adrenalin Edition

Since I saw an improvement and having fun with this underclocking test, i thought maybe this would be fun for someone to try out and compare the results.

My system:

AMD Ryzen 5 5600G

Gigabyte B550M DS3H

Gigabyte Radeon™ RX 7600 GAMING OC 8G
