AMD Ryzen 7 7800X3D Overclocked To 5.4 GHz By SkatterBencher

Pieter “SkatterBencher” Plaisier, as usual, has come up with a comprehensive video and article where he shares his extensive knowledge on overclocking the X3D processor. In his usual easy-to-follow style, he provides detailed explanations, complete with graphs and diagrams, of various strategies for overclocking the latest CPU designs, including the Ryzen 7 7800X3D with 3D V-Cache. This is a great opportunity for those who are not familiar with the overclocking community to catch up on the latest changes in CPU designs and learn about the intricacies of overclocking.

Yesterday, AMD lifted the embargo on reviews for the 7800X3D, and SkatterBencher wasted no time in sharing benchmarking results. Interestingly, unlike most reviewers, Pieter’s focus was on overclocking, which is ironic because this CPU is not officially designed for overclocking. AMD has locked frequency and multiplier overclocking on their 7000X3D series, but Pieter found ways to speed it up despite these limitations.

The overclocker delved into various options to make the 7800X3D CPU faster, including utilizing Precision Boost Overdrive 2, curve optimizer, EXPO for memory overclocking, or asynchronous ECLK adjustments using an external generator. Among these, a combination of PBO2 and ECLK adjustment proved to be the most effective overclocking strategy, although also the most complex.

In the end, the overclocker achieved an impressive 5.3 GHz clock boost in the SuperPI one-thread boost test, with two cores coming close to hitting 5.4 GHz.

Although SkatterBencher’s successful overclocking attempt demonstrates that higher frequencies can be achieved on the 7800X3D, it’s important to note that the path he chose is not advisable for most users. The X3D series is not intended for overclocking, and tinkering with voltages or external clock generators can lead to stability issues. Moreover, the 7800X3D CPU is already exceptionally fast out of the box, and there is limited need for most users to seek additional performance enhancements.

SkatterBencher is currently experimenting with various overclocking methods, some of which have already yielded positive results with CPU-Z validations at 5.6 GHz. However, it’s worth noting that the outcome may differ depending on the specific processor. SkatterBencher cautions that due to the 7800X3D CPU’s extreme sensitivity to voltage, it is not recommended to exceed 1.15V to avoid potential stability issues.
