AMD Ryzen 7 5800X3D gets BCLK overclocking on MEG X570 series
MSI is releasing a new AGESA firmware update for the Ryzen 7 5800X3D processors that will enable BCLK overclocking.
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 Ryzen 7 5800X3D processors, but only for enthusiast motherboards based on the X570 chipset. The report says the BIOS will support MEG X570 GODLIKE, Ace and Unify series, hence motherboards with external clock generators.
It’s important to note that BCLK overclocking for the 5800X3D processor has been demonstrated extensively in some independent tests last week, but it’s neither easy nor recommended for this processor. AMD’s first consumer-grade CPU with 3D V-Cache wasn’t designed with overclocking in mind, and some reports even claim it could have a negative long-term impact on the combination between chiplets and 3D-Cache. But neither AMD’s advice nor the lack of official overclocking support will stop tinkerers (and motherboard makers, of course) from taking full advantage of the most innovative AM4 processors released to date.

The screenshot posted by MSI shows that with BCLK set to 107 MHz, the CPU will run at around 4.87 GHz and 1.328V. In such a configuration, the CPU would score 1596 points on the Cinebench R23 single-core test and 15488 on the multi-core test. Compared to the default BCLK of 100 MHz, this improves performance by 7.5% and 4.9%, respectively.

The AMD Ryzen 7 5800X3D is clocked 200 to 400 MHz lower than its older brother without 3D V-Cache (5800X). In some tests that didn’t take advantage of the extra 64 MB of L3 cache, the processor might actually end up being slower. The BCLK adjustment should balance the performance difference with the 5800X.
