After tweaking the RAM and even before modifying the CO values of the CPU I decided to modify the FCLK.
The RAM were tested with 10h of TM5 with the anta777 ryzen3D profile and 6h of Karhu.
Ram temps are not a problem as they are always below 35 degrees.
I started testing the fclk at 2200mhz with linpack and I have a very small variation in the order of the second or third digit after the decimal point.
This it cannot be said of VT3.
Here I have a variation of +/- 0.3 / 0.4 even with stock bios values (neither Expo), same thing for 6000mt's and fclk at 2000mhz, I have also tried to increase / decrease the Voltages.
My doubt comes from the fact that I see results in posts with literally no variation.
I even made sure, reading the advice of some users that VT3 with furmark could be useful to test their stability. Here I realized that with VT3 and Furmark I had an even lower variation than only VT3 and nothing in the background.
I hope someone can shed some light on this for me.
