MSI Kombo Strike For AM4 500-Series Motherboards Released: Up To 5% Performance Uplift & Undervolting Support For AMD Ryzen 7 5800X3D CPU Through BIOS

Kombo Strike is a brand new feature that's being introduced by MSI for its AM4 500-series boards.  The feature comes packaged in the latest BIOS for MSI's 500-series motherboards which not only add the Kombo Strike feature for the Ryzen 7 5800X3D CPU but also unlock undervolting support for the chip.

So what is the Kombo Strike feature? Based on the description, it looks like MSI unlocked a higher power limit for the AMD Ryzen 7 5800X3D as they state that the performance gain may depend on the cooling solution used. A premium CPU cooler is recommended which means that under AIO, a performance uplift of up to 5% can be gained. The feature can be found within the Overclocking / Advanced CPU Configuration panel and has four options: Disabled, 1, 2, and 3. The bigger number obviously means better performance but it also means that you need a better cooling solution to take full advantage of your chip.

We have some performance numbers too in Cinebench R23 where the AMD Ryzen 7 5800X3D gains a slight improvement in single-threaded performance but a 5% improvement if we compare the stock chip with the one boosted by Kombo Strike on MSI's AM4 500-series motherboards.


The other feature that's being added to MSI's AM4 500-series motherboard is BIOS undervolting support. The new BIOS adds a 'CPU Offset Voltage' option with a (-) offset which can be used to undervolt the AMD Ryzen 7 5800X3D CPU. We have seen that undervolting the 3D V-Cache chip delivers similar performance with lower power consumption and lower temperatures. MSI warns that too much lower CPU voltage can lead to system instability.
