Ryzen 9 7900x3d FCLK & Settings

[Orodruin]

Hello everyone;

My default settings are as follows.
I am using Ram Settings "EXPO Tweaked".

As far as I know, many people recommend setting FCLK to 2133. I have never tried this with AM5.
After manually setting FCLK to 2133, what voltage will I need to increase?

Since I have an Asus motherboard, I am using it with ENHANCEMENT selected from the PBO settings and the thermal limit is 80 degrees.

Try FCLK at all speeds up to the max it can get.
1.289V SoC is already high. You should try lower voltage with any speed. I wouldn’t like it close to 1.3V for 24/7. More like 1.2 or lower.
There was a chance also that FCLK can OC better with low -er SoC voltage. Word going around says that FCLK does not like high SoC voltage.

Hello @Zach_01 how are you? We have talked about it in different topics before, you helped me.

How many should I enter and set this SOC voltage manually?
After setting FLCK manually to 2133, will I gradually decrease the SOC voltage?

To get my 7900X3D stable at 2133 FCLK I need to set the VSOC to 1.245V in the BIOS. However, it's not guaranteed that every 7900X3D will be stable at that FCLK.
If not already known, in general you need to test memory stability without booting into Windows as in the worst case your Windows installation may be irreparably corrupted. For testing stability you may use a tool like e.g. MemTest86 and put it on a bootable USB stick.
