Asus overclocker SkatterBencher revealed a new video as we speak the place he was capable of overclock AMD’s greatest CPU for gaming, the Ryzen 7 7800X3D to five.4GHz, regardless of the chip’s overclocking limitations. He efficiently bypassed AMD’s 5 GHz ceiling through the use of exterior clock turbines to overclock the CPU cores.
AMD’s Ryzen 7 7800X3D is the brand new gaming champion amongst PC processors, delivering blisteringly quick gaming efficiency with the assistance of 3D V-Cache expertise. Nonetheless, the thermal limitations of the 3D stacking tech have compelled AMD to disable handbook overclocking on the chip, except for Precision Enhance Overdrive or PBO and AMD’s Curve Optimizer.
SkatterBencher was capable of get round this downside with the assistance of an Asus ROG Crosshair X670E Hero that has not one, however two exterior clock turbines to assist in overclocking. To realize 5.4GHz, SkatterBencher used a novel mixture of a number of options, together with the exterior clock generator, Precision Enhance Overdrive, and AMD’s Curve Optimizer to spice up clock speeds.
This overclocking technique is sophisticated, however the execution could be very efficient. Precision Enhance Overdrive is used to forestall energy limitations from occurring on the chip. The exterior clock generator is used to bodily increase clock speeds, and the curve optimizer is used to — not undervolt — however overvolt the chip past inventory voltages to maintain clocks secure.
This led to a 5.4 GHz peak increase on a single core, with a 4.85 GHz increase clock on all eight cores at voltages nicely underneath 1.2v. This represents a 7.7% increase to spice up frequencies and a ten% increase to single-core clocks in comparison with inventory frequencies.
The overclock could be very spectacular and exhibits how a lot headroom is definitely accessible in a few of these chips. Solely time will inform how rapidly the 7800X3D will degrade with the overvolt utilized, however the overclock is spectacular nonetheless. With a clock of 5.4 GHz, you successfully have the identical compute efficiency as a normal Ryzen 7 7700X with the extra L3 3DV-Cache to spice up gaming efficiency.
