One of the administrators of the official MSI form released Beta BIOS for the MEG X570 Unify motherboard, adding previously unavailable settings to overclock the latest Ryzen 7 5800X3D processor.
Officially, the Ryzen 7 5800X3D chip does not support overclocking. AMD has blocked the ability to change the chip’s frequency and power settings in the BIOS of motherboards. Unfortunately, the option of reducing the processor’s operating voltage also fell under the knife. However, some motherboards based on the AMD X570 chipset are equipped with external clock generators that allow you to overclock the Ryzen 7 5800X3D by boosting the BCLK bus.
According to forum administrator MSI, the E7C35AMS firmware for the MEG X570 Unify motherboard unlocks the ability to change VCore settings, Precision Boost Overdrive (PBO) and use the AMD Curve Optimizer overclocking tool. At the same time, the administrator draws attention to the fact that MSI does not recommend users to overclock the Ryzen 7 5800X3D, you can do this only at your own peril and risk.
In addition to the firmware itself, an MSI representative shared screenshots of the synthetic Cinebench R23 test he ran on an overclocked Ryzen 7 5800X3D. Unfortunately, he did not specify what settings were used when overclocking the chip, but as a result, the multi-core performance of the processor increased by 4.7%. No manipulations helped with the single-thread performance. The chip only got 1% faster, which is within the margin of error.
As mentioned above, the new MSI firmware is in beta testing. In other words, it will be further developed. At the moment it is not known if MSI will only stop with the MEG X570 Unify board or if it plans to release similar BIOS versions with Ryzen 7 5800X3D overclocking capability for other models of its boards. It is also not known whether other manufacturers want to follow suit. MSI also does not say when the official version of such firmware will be ready.
