Hi, there,
With the idea of increasing the performance of my hardware without taking too much risk, I overclocked the DRAM and my CGU, I didn't touch the CPU.
To overclock it, I used : DRAM Calculator for Ryzen by choosing the "Calculate Safe" option and I changed the timings via MSI Command Center (I had already changed the frequency from 2166MHz to 3000MHz via the BIOS and took the XMP 2933MHz timings).
I saw that the CPU had a lot to gain.
I then proceeded to overclock my graphic card, to do so, I used MSI Afterburner following the instructions here
As for the DRAM OC, it's the software that calculates the best settings, I increased the VRAM memory by 991MHz by hand, because I had read that it was a graphic card that had a high OC potential thanks to the VRAM memory OC, and I read in comments that the maximum value before crash was 1000MHz.
I changed two settings under "NVIDIA settings" :
Results :
I'm happy with the results, the hardware does not heat up and the games work in very good quality (often in Ultra).
Performance is equal to and even better than GTX 1660 Ti and Super "stock".
