AMD’s Ryzen 7 7800X3D is the best gaming chip on the market, but let’s face it, the Ryzen 9 variants are kind of redundant. Despite official fixes and compatibility patches, there are some games where the Ryzen 9 7950X3D and the 7900X3D perform notably worse than their Ryzen 7 sibling. Fortunately, there’s a fix. The following chart from Graphically Challenged promises a 23% performance boost in gaming workloads with a simple BIOS modification.
All you need to do is set boost clock limits for the vanilla (non-X3D) Zen 4 cores on your Ryzen 9 7950X3D. And that, too a relatively lower upper limit. You see, by default, the V-Cache die on the Ryzen 9 7950X3D, and 7900X3D comes with a lower boost clock than the vanilla Zen 4 die due to thermal restraints. This tricks some games into thinking that the vanilla Zen 4 cores are more apt for gaming than their V-Cache variants.
To undo this, you need to go to the BIOS and search for “Per Core Boost Limit“. There, you need to limit the boost clock of Core 8 through Core 15 to 5,050MHz. This allows the Windows 11 scheduler to utilize the V-Cache die for gaming workloads, delivering R7 7800X3D-level performance and more:
