Asus overclocker SkatterBencher printed a new video lately the place he used to be in a position to overclock AMD’s perfect CPU for gaming, the Ryzen 7 7800X3D to five.4GHz, regardless of the chip’s overclocking boundaries. He effectively bypassed AMD’s 5 GHz ceiling via 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, turning in blisteringly speedy gaming efficiency with the assistance of three-D V-Cache era. Then again, the thermal boundaries of the three-D stacking tech have compelled AMD to disable guide overclocking at the chip, apart from Precision Spice up Overdrive or PBO and AMD’s Curve Optimizer.
SkatterBencher used to be in a position to get round this drawback with the assistance of an Asus ROG Crosshair X670E Hero that has no longer one, however two exterior clock turbines to assist in overclocking. To reach 5.4GHz, SkatterBencher used a novel aggregate of a couple of options, together with the exterior clock generator, Precision Spice up Overdrive, and AMD’s Curve Optimizer to spice up clock speeds.
This overclocking technique is sophisticated, however the execution may be very efficient. Precision Spice up Overdrive is used to forestall energy boundaries from going on at the chip. The exterior clock generator is used to bodily spice up clock speeds, and the curve optimizer is used to — no longer undervolt — however overvolt the chip past inventory voltages to stay clocks solid.
This ended in a 5.4 GHz height spice up on a unmarried core, with a 4.85 GHz spice up clock on all 8 cores at voltages smartly underneath 1.2v. This represents a 7.7% spice up to spice up frequencies and a ten% spice up to single-core clocks in comparison to inventory frequencies.
The overclock may be very spectacular and displays how a lot headroom is in truth to be had in a few of these chips. Most effective time will inform how briefly the 7800X3D will degrade with the overvolt implemented, however the overclock is spectacular nevertheless. With a clock of five.4 GHz, you successfully have the similar compute efficiency as a typical Ryzen 7 7700X with the extra L3 3DV-Cache to spice up gaming efficiency.
