M: YES released a new AGESA firmware (1.2.0.07) that allows overclocking AMD Ryzen 7 5800X3D, yes, only BCLK, remembering that AMD itself advise against overclocking your CPU due to the use of its new 3D V-Cache technology, which could lead to long-term negative effects as this memory and voltage changes do not make very good friends.

AMD Ryzen 7 5800X3D @ 4868MHz

This possible risk must be sufficiently valued, because for the moment it has only been reached increase the frequency by 107 MHzthereby running the processor at approximately 4868MHz with a voltage of 1328Vwhich makes the best single-core performance gain of 7.5% (in Cinebench R23 –1485 against 1596 points-), while multi-core performance increases by 4.9% (-14759 against 15488 points-), so it’s not a noticeable improvement considering the risk, although in applications where the cache improvement isn’t taken advantage of, it at least helps it compete with the Ryzen 7 5800X itself, where in these cases it is superior by offering factory frequencies of up to an additional 400 MHz.

“It is important to note that CPU BCLK overclocking on AMD Ryzen CPU platforms will affect the stability of PCIe, SATA, and M.2 devices. So the maximum BCLK overclock you can get from your chip is highly dependent on part of your CPU, graphics card and SATA/M.2 SSD Newer graphics cards like Nvidia GeForce RTX 20/30 series are very susceptible to BCLK overclocking and can become a bit unstable when overclocking Ryzen CPU 7 5800X3D”.
