AMD Ryzen 7 7800X3D Already Overclocks to 5.4 GHz

An Asus overclocker published results on the 6th of April 2023 where they were able to achieve a 5.4Ghz despite the CPU’s overclocking limitations. External clock generators were used to bypass the 5Ghz barrier.

Amd’s Ryzen 7 7800X3D is, as of this writing, one of the worlds fastest gaming processors. Able to deliver incredibly fast gaming performance with the use of AMD’s 3D V-Cache technology. There are, however, thermal limits of 3D V-Cache. This Forced AMD to disable manual overclocking, except for Precision Boost Overdrive (PBO) or AMD’s Curve Optimizer.

The overclocker was able to circumvent this problem with the help of a specific motherboard – the ASUS ROG Crosshair X670E Hero, which boasts not one, but two external clock generators to help when overclocking. To understand clock generators, think of them as pacemakers for processors and various other integrated circuits on a motherboard. They keep a standard rate at which instructions are processed by the CPU and set how often data moves about the motherboard to various components. Having multiple external clock generators for overclocking is useful because it helps get around processors with internal clock generators which are locked, like in the Ryzen 7 7800X3D.

We won’t be getting into the specific overclocking strategy used to achieve these results, but the overclocker used the external clock generator, PBO and AMD’s Curve optimizer. Overall, the overclock yielded a 7.7% in boost frequencies and a 10% boost on single core clocks at well under 1.2V. This is very impressive for a locked CPU, however only time will tell how quickly this chip will degrade with an under-volt applied. Which brings us to our next point.

Overclocking a processor essentially voids the warranty, for example, AMD will not warrant any damage done to a processor by overclocking. Basically, if you overclock your CPU and it dies during the warranty period, your warranty is voided. This is why we don’t suggest overclocking if you want to keep those warranties intact. The performance benefits over overclocking don’t always outweigh the cost of losing a warranty.

We suggest that instead of overclocking a slower processor to rather bite the bullet and get a chip that will perform as needed from the get-go. It does, however, remain interesting to see just how close to the bleeding edge those who are willing to take the risk can get.
