When I first saw coverage of the 7800X3D by the Tech Media/YouTubers I saw a glaring omission on their part with regard to getting the most out of the CPU.
 
It was a howler of an oversight and, although I have a 7950X, I felt compelled by my own curiosity to buy a 7800X3D because I thought to myself, "Surely they can't be THIS idiotic and overlook something so obvious".
 
The very first step to getting the most out of your 7800X3D is cooling.
 
For Ryzen, 10 degrees Celsius equals approx. 100 MHz in clockspeed. What this means is let's say for instance your CPU runs at 80 degrees Celsius at 4.5 GHz then if you managed to cool it down by 10 degrees (i.e. to 70 degrees) it will run at 4.6 GHz without you doing anything else for the same load.
 
In my opinion, the best price/performance cooler that you can get at the moment is the Arctic Liquid Freezer II 360.
 
Another thing to consider is the airflow of your case, if your case is a sweat box then there isn't much even the best cooler can do.
 
Given you have good cooling, your results should be better than mine, because I have to keep my room temp at 30 degrees Celsius because I have had two spine operations and have spinal arthritis.
 
Here are the steps you have to take to optimally configure your 7800X3D.
 
In your BIOS (assuming you have the latest BIOS for your motherboard downloaded and applied) do the following:
 
1) Max out the LLC for your CPU Vcore. This means that the limited amount of voltage available to the 7800X3D is maximised, and the voltage won't droop under load.
 
2) Activate PBO.
 
3) Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable. In my case, that is "39".
 
Without maximising the LLC the highest my CO would go was marginally stable at "-30" but with the LLC maximised it is rock solid steady at "-39"
 
Doing this has given me far higher benchmark scores than ScatterBencher has managed in his video on overclocking the 7800X3D.
 
It has also given me a higher result than Frame Chasers managed to achieve with delidding his 7800X3D, applying liquid metal, lapping his IHS and using a custom loop cooling, all at a lower temperature.
