Hello guys, This is my system:

Gigabyte Aorus X370 Gaming k5
AMD RYZEN 1700x
DeepCool Captain 240EX AIO cooling
16 GB RAM @2933 Mhz

So this motherboard has a OC button... I suppouse this button will automatically OC the cpu to some kind of tested settings, probably not the highest potential speed this cpu can achieve but a little lower but surely stable OC without the hassle. If i am correct i would like to give it a try, my question is when do i have to press this button? With the system turned off? On at the Bios or at Windows?

I do have little experience with OC prior to this ryzen 7 i had a FX8320e running at 4.3 Mhz, it was a fun process getting that OC, but as of right now don't feel like putting the time to get a manual OC on this RYZEN 7... So if this OC button can give me a little performance boost with out any hassle i will take it. Hope you can help me out.

those "magic" buttons are a complete crap.
They push way to high voltages to achieve target clocks.
It would be much better idea to do the overclock manually.
play with core voltage up to 1.4v and see how far you can push the multiplier. you should be able to end up somewhere between 3.9 and 4.1GHz.
watch the temps under load.

ok... will a CPU OC affect or be affected by the fact that in order to get the RAM to run at 2933 Mhz i had to manually set the frequency and play a little with timings?? It is not overclocked since the dims are Gskill TridentZ 3200Mhz (couldn't make them run at 3200 mhz) i didn't mess with ram voltages....

Actually, with Ryzen have quite positive influence of CPU to RAM and vice versa OC. Higher OC of CPU enables higher OC of RAM. Carefull OC of CPU + OC of RAM can produce dramatically better results. Dual channel RAM also has much larger effect than on FX processors, also responds very well on lower latency.
Problem with those "Auto OC" ways is that it doesn't do any dramatically high OC but may introduce unnecessarily high voltages (someone's idea for stability).

Thank you both for your replies, taking in mind your imputs i decided to take a few minutes to do a maunal OC, i managed to get to 3.8 Ghz (wich is the same as the stock turbo speed for this cpu) with a very minor voltage increase... I am leaving it like that for the the time being (i did notice some performance increase while video editing) i will try to a do a propper OC later when i have the time to see if i can get to 4.0 Ghz

Thank you again for your help
