The AMD Ryzen 7 7800X3D has been tested using EK’s premium liquid cooling kit where it was able to achieve 400 MHz over spec. The AMD Ryzen 7 7800X3Ds is the direct follow-up to AMD’s first offering, the 5800X3D, which featured 3D V-Cache technology. Both 8-core/16-thread processors are on a single CCD. Brent Justice reviewed the new CPU where it showed off admirable improvements over its predecessor for gaming. Due to the engineering required in layering the 3D V-Cache AMD does not recommend overclocking these processors as they can be very susceptible to damage. However, if one is extremely careful there could be some gains to be made in getting past the 5.0 GHz boost clock but it is a risky venture.
Overclocker Pieter Plaisier (SkatterBencher) has provided extremely detailed data, and a video, on how the new processor can reach up to 5403 MHz, and possibly even higher. A parts list is also included where we can see that EK’s premium liquid cooling kit, along with an ElmorLabs fan controller and booster adapter (for increased reading accuracy), was used tame the new processor. Beyond that, most parts are pretty straightforward, no LN2 but the system was powered by an Enermax MAXREVO 1500W power supply and used DDR5-6400 memory.

Mind the Voltage
SkatterBencher notes that users should never increase the voltage beyond 1.15V as doing so is likely to damage the processor. As is, increasing the voltage is already a risky endeavor with these processors so extreme caution should be taken. The 7000X3D series is not designed for overclocking and, like the previous 5800X3D, has locked multipliers but there are still ways via PBO2, curve optimizer, memory overclocking, using asynchronous ECLK (something other users did with the 5800X3D). One thing the X3D series of CPUs has brought back is the technical aspect of overclocking and the many combinations of PBO2 and ECLK adjustments show this.
From SkatterBencher (via VideoCardz):
“Overclocking the 7800X3D was one of the most enjoyable Ryzen 7000 tuning experiences. There are plenty of overclocking strategies to choose from, and it definitely feels like the deeper down the rabbit hole you go, the more extra frequency you can find.
But I must emphasize that voltage is the most significant danger for 7800X3D overclocking. I do not recommend using a manual voltage of over 1.15V because any load will push the CPU to TjMax or beyond. Thermal choking caused by excessive voltage will most certainly damage your CPU.”
SkatterBencher also posted a screenshot showing up to 5.6 GHz with a voltage set to 1.087V which indicates with proper cooling and more fine tuning there is still a bit more headroom for this impressive processor. The overclocker did not provide much more info on this achievement so it’s possible there is still more testing being done to maintain stability.
