The maximum CPU core voltage the B450 Tomahawk supports is 1.55 V which is considered overkill and could dramatically reduce the lifespan of the processor when left under 24/7 conditions and a maximum recommended CPU VCore of 1.45 V with adequate CPU cooling I would recommend staying below 1.4 V for a good balance of core frequency, power draw and core temperature when using a decent CPU cooler. One thing to note was when the CPU Core Voltage setting was altered from auto, it would disable AMD's Cool'n'Quiet power saving feature. Manually overclocking was painless as pushing our chip to its maximum stable core frequency of 4.0 GHz required two settings to be altered the CPU ratio to x40 and the CPU Core Voltage to 1.375 V. This will apply different settings depending on which model of processor you have installed, but for our Rythis meant it would overclock our chip to 3.2 GHz with a CPU core voltage of 1.2 V. Users looking to apply the Game Boost pre-defined overclocking profile can do so from the initial EZ mode splash screen by clicking the button to the ON position.


When it came to overclocking our Ryprocessor within the MSI Click BIOS 5 firmware, all of the key options required to overclock the processor was found within the OC section.

From glancing over a lot of different boards specifications from the main vendors, a lot of focus has been on power deliveries and packing them full of unnessesary doubled inductors without a true increase in quality. MSI has been one manufacturer to bolster and upgrade their power deliveries and the differences between the B350 Tomahawk and this newer B450 Tomahawk are more than enough to paint a picture from MSI that overclocking and stability is a key area they've improved upon. This is great for users with the right components to push their processors and memory above and beyond the default settings. Ryzen Overclocking Experience With the MSI B450 TomahawkĪside from the very basic and barebones A320 chipset, all of AMD's other AM4 chipsets which includes B350, X370, B450 and X470 all allow for overclocking.
