You can’t overclock the AMD Ryzen 7 5800X3D and here is why

The AMD Ryzen 5800X3D is not overclockable and that has been confirmed by the company’s Marketing Director. Remember that the Ryzen 7 5800X3D is the first consumer-oriented processor from AMD to feature the 3D V-cache technology. The primary reason why the CPU cannot be overclocked is that AMD’s 3D V-Cache cannot work at high voltages.

According to Robert Hallock, director of technical marketing at AMD, he said: “As people know, this is our first CPU with 3D V-Cache technology […] and that packaging technology in our space has different voltage and frequency scaling than people may be accustomed to,” he added. “On the desktop parts you’ve seen us ship parts that range up to 1.45V or even 1.5V in boost and that is not the limit for 3D V-Cache. The voltage limit on that is more like 1.3V to 1.35V.” 

“So, we are not going to allow CPU frequency overclocking or core voltage adjustment because out-of-the-box the design of the chip already uses ranges up to that voltage and frequency limit. On the other hand, fabric overclocking remains enabled, memory overclocking remains enabled, and we know that our parts get the most benefit from that anyway. […] We are working very hard to maximize our out-of-box performance for people and this is a very new thing we are trying.”

Possibly, structural silicon and its impact on heat dissipation add to AMD’s hesitance to allow overclocking of its Ryzen 7 5800X3D part, but it seems the 3D V-Cache voltage capacity is the main reason. Just as Robert Hallock, director of technical marketing at AMD revealed during a HotHardware broadcast.

Additionally, even though the Ryzen 7 5800X3D is not overclockable, AMD is fully convinced of its prowess when it comes to gaming.  According to AMD the Ryzen 7 5800X3D processor with a 96MB L3 cache is aimed at gamers. So the 3D V-Cache may not be that efficient for other types of applications aside from gaming.
