Recently, Asus has launched a new BIOS 3101 for AMD 400 series motherboards, which integrates the latestAgesa comboam4 184.108.40.206 microcode, but neither ASUS nor amd has disclosed what's new in this update.
Some players have studied on a Rog crosshair VII hero (x470) motherboard and confirmed that the microcode version is indeed 220.127.116.11. At the same time, they found that at least on this board, Independent overclocking for each CCX of the sharp dragon processor is supported.
The so-called CCX (CPU Complex), is the basic module of the AMD Zen architecture, including 4 physical cores and the corresponding cache, it is using this basic module that can be superimposed to obtain higher specifications of the product, each two CCX to form a CCD chip, and then stacked all the way to the 64 core.
At present, players can be overclocked separately for different CCX, and the advantage is that they can tap utilize the physique and potential of different CCX to obtain the highest possible performance.
However, it is not confirmed which processors this function supports, whether it can be used by the second and third generations of sharp dragon, or only by the third generation of sharp dragon. It is not clear whether this is the function of AMD microcode or Asustek's addition.
This is a CCD, and two parts are two distinct CCX.
