AMD’s Robert Hallock told enthusiasts last month that red team’s first Ryzen chip with 3D V-Cache technology, the Ryzen 7 5800X3D, would not support traditional overclocking and was effectively hard locked from exceeding its published specifications. A YouTuber by the name of SkatterBencher has now seemingly proven Hallock wrong, having published a video on his YouTube channel that demonstrates how the chip can be driven beyond its official maximum boost clock of 4.5 GHz. This can apparently be done through BLCK, a form of overclocking that usually results in an OC of not just the CPU, but every other component on a motherboard, including RAM, PCIe slots, and more. SkatterBencher was able to take AMD’s Ryzen 7 5800X3D maximum boost clock of 4.5 GHz to 4.7 GHz.

Thanks to voltage offsets and Asus’s specialized Voltage Suspension feature, SkatterBencher was able to override AMD’s maximum voltage output of 1.35v for the 5800X3D, to a maximum voltage of 1.375v.

Voltage Suspension is a unique feature offered by Asus that allows the user to set voltages against specific temperature targets, allowing the CPU to utilize higher voltages at lower temperatures, and pulling back voltage at higher temperatures to preserve the CPU’s health.

In Prime95 testing with small FFTs and AVX enabled, the 5800X3D managed an all-core clock speed of 4.21GHz at 1.176 volts, with peak temperatures running at 93.4C.
