Overclocking ASRock Radeon RX 7600 XT Steel Legend 16G OC
Our overclocking of the ASRock Radeon RX 7600 XT Steel Legend was very straightforward and also quite good. We had a choice of two pieces of software to use and ended up using the Adrenalin Performance software in the driver package. 
ASRock does have a software called ASRock Tweak Version 2.0, which is quite easy to use once you figure it out. However, when we compared results using the exact same settings and benchmarks, ASRock Tweak 2.0 was consistently 3-7% below our FPS results gained using Adrenalin. We believe the difference is the ability to set a minimum frequency AND maximum frequency in Adrenalin which gives that extra push. 
Our only gripe with the ASRock software is there is no instruction anywhere on how to use it. We simply had to figure out what did what by trial and error. To overclock manually, one clicks on “user mode” which allows adjustments as you see in the screen capture. ”OC Mode” is a mystery, as enabling it made no difference we could see and no adjustments can be made.
We have screen captures of both software versions final settings below. We could adjust minimum and maximum GPU frequency, memory frequency, power limit, and fan cycles in Adrenalion and likewise Tweak 2.0 excepting the minimum.
Using Adrenalin we set a minimum GPU frequency of 2950MHz and the maximum at 3050MHz. The power limit slid all the way out to 20% and the memory increase was capped at 20Gbps. We left the fans on automatic. The fans were nearly silent all along and the temperatures were very cool. A really excellent cooling solution. The results overall are quite good.
So, the baseline Game Clock on a 7600 (plain) is 2250MHz. The “reference clock” on a RX 7600 XT is 2470MHz. The base Game Clock on our ASRock Radeon RX 7600 XT Steel Legend is 2539MHz. You can clearly see that the base XT version is already 10% overclocked and our ASRock RX 7600 XT is another 3% beyond that, right off the shelf. Put another way, the ASRock RX 7600 XT Steel Legend is 13% overclocked versus a plain RX 7600 without doing anything.
Now when we evaluate our card on the benchmark, we see that the default FPS averages 2655MHz. That is a full 115MHz past the factory overclocked Game Clock, and very steady. When we applied our overclock we attained an average of 2809MHz! That is 270MHz beyond the factory overclock or 10%. Looked at from the “reference” value, 13%, and finally from the 7600 plain “reference”, 24%. That’s pretty good right there! Let’s see if it translates in real-time gaming.
