RX 6800 XFX speedster SWFT (the entry level model) UV/OC Results

Hi guys, it's the first time I've approached heavy overclocking, until now I've only limited myself to managing frequencies and voltage in a very light way.
After studying a bit on various sites, I chose to try to test my GPU by taking it to the limit.

The stock values are: boost frequency 2239mhz / voltage 1025mV / power limit 203W / Vram 2000mhz

I tested a whole afternoon on cyberpunk in 4k high Xess UltraQ, I had the first and only crash bringing the voltage to 870mV without losing performance, after about 1 minute the game closed and adrenaline restored everything.
So I went back and set it to 890mV and I didn't have any crashes for over 1 hour on Cyberpunk.
I then proceeded to raise the frequencies from 2239 to 2450 and the power limit to +10% (it doesn't go above that) at 223W
I also increased the Vram frequencies by 7% (max limit)

The GPU gained about 9% in performance, going from 59fps to 64fps with fans at 1400rpm at 53 degrees celsius and hotspot 64.
Even surpassing the 4070

I adjusted Voltage and frequency so that the GPU was just under the 223watt limit, so it oscillated between 222W and 223W, beyond that it was limited by the power limit and lowering the voltage further would have caused it to crash.

Now I have brought everything back to standard value and I only did an undervolt from 1025 to 920, just to keep it very cool without losing performance.
I am writing this post to ask you more experienced people if I have proceeded well in testing the limits of the card. And I also wanted to know what you think about the low voltage? I honestly expected worse silicone from an entry level model, but instead I was surprised.

P.S sorry if there may be grammatical errors but English is not my first language.

That's perfect for a daily gaming tuning!

Now if you just want high benchmark scores like for HWBOT points, you'll have to use MPT from Igorslab. You can really go crazy with that but watch hot spot, especially air cooled. I do not recommend running the card with MPT for daily usage.

Thanks, I didn't know about HWBOT and MPT. I'll go take a look.
Regarding the overclocking method that I did, do you think it's correct? Keep the voltage lower until stable and increase the frequencies until you can get a performance gain? I noticed that once I reached the limit of 223W I didn't get any more improvements, so I stopped at 890 and 2450. However, I noticed that despite these values, the GPU couldn't stay under the limit of 890 because for those frequencies the card required more voltage. So it went up around 960mV in the graph and the frequencies around 2360mhz. Why? Maybe it's set like this by the vbios?
Thanks if you can answer me

Yes that is probably the best method for overclock while keeping power draw and temperature within reason.

MPT allows you to raise the power limit as high as you want, and raise voltage, to allow you to clock it as far as you can cool it, but it is dangerous.
