Wccftech reports that MSI will be rolling out an update to AGESA 1.2.0.7 in the coming days. This firmware update will enable BCLK overclocking for the Ryzen 7 5800X3D processor, but only for enthusiast motherboards based on the X570 chipset. This BIOS will support MEG X570 GODLIKE, Ace and Unify series, so motherboards which have external clock generators, the report claims.
 
It should be noted that BCLK overclocking of 5800X3D processor has been extensively demonstrated in some independent testing last week, but it is neither straightforward nor a recommended use for this processor. AMD’s first consumer CPU with 3D V-Cache was not designed with overclocking in mind, with some reports even claiming that it might have negative long-term effects on the bond between the die chiplet and the 3D-Vache. But neither AMD recommendations nor lack of official overclocking support would stop tinkerers (and clearly board makers) from taking the full advantage of the most innovative AM4 processor released thus far.
 
With BCLK set to 107 MHz, the CPU will run at around 4.87 GHz and 1.328V, a screenshot released by MSI shows. In such a configuration the CPU would score 1596 points in Cinebench R23 single-core test and 15488 multi-core. That’s respectively 7.5% and 4.9% higher performance compared to default BCLK of 100 MHz.
 
AMD Ryzen 7 5800X3D is clocked 200 to 400 MHz lower than its older sibling without 3D V-Cache (5800X). In some tests that do not take advantage of the additional 64 MB of L3 cache, the processor might actually end up slower. The BCLK adjustment should even out the performance disparity against the 5800X.
 
AMD doesn't want consumers to overclock the 5800X3D. Hopefully this overclocking won't damage the processor.
