OCing a graphics card requirements

[2018amdbuild]

not considering doing it anytime soon but was wondering about the following for gpu oc -

does it require cooling solution? if so what sort of  cooling?

how does one actually go about it?

do gpu oc cause stability issues with the system? and if so then how easily does this instability come about?

sorry for the general questions, completely new to this.

Pretty straight forward. Download Afterburner app and install. Check on-line what kind of overclock you can archieve with you GPU. Apply the same overclock and see what happens. 

3 factors, Core overclock, memory overclock and fan speed. 

Up the core clock little by little doing some benchmarks everytime you apply some more core clock & the same with the memory. When you start to see artifacts (something like errors on the screen, coloured pixels) pull back a bit and that is supposed to be stable. Also create a more aggresive fan curve to be sure your GPU stays cool. 

after that, you can start to up the voltage, but I never do that. Maybe someone else can help you with more xp. 

The worst that can happen without increasing the voltage is that your driver crash and go back to default.

1. Cooling solution can be done via waterblock, or get a card with a nice cooling system in it. ie the MSI TRIO, EVGA FTW3, ASUS Strix. Other than that it'll be dependent on the load, ambient room temp, case airflow, etc

 

You need to download programs such as Unigine Heaven, MSI Afterburner, there are tons out there. 

 

Stability issues come with an overdone overclock, if that happens than turn down the OC. Memory speed, clock, voltage and so on. 

Instability will be noticeable with stuttering, flickers, color changes (like a patch of green pixels)

Honestly if you are using a 10 series card there isn't alot to gain as most cards get pretty close to their limit with gpu boost 3.0
