It is well known that overclocking can damage our components past a certain threshold. All products have been designed with the idea that by fate they could be overloaded, but overclockers want to get the most out of their components, especially if they are high-end. The AMD Ryzen 7 5800X3D processor will be the first to include the AMD 3D Cache and there are those who will make their mouths water thinking about their overclocking.
But recent reports throw a jug of cold water. It has been reported that the AMD Ryzen 7 5800X3D is not only not overclockable, but rather it hurts a lot more than normal to do it.
Better not overclock your brand new AMD Ryzen 7 5800X3D
The launch of AMD's Ryzen 7 5800X3D processor is getting closer, and they already warn us that this CPU with 96MB of cache might not support overclocking. This information comes from a user of the Chinese portal Bilibili. And it is not the only report on this use case.
TechPowerUp added that AMD is asking its motherboard manufacturing partners to disable overclocking on the Ryzen 7 5800X3D. PC Gamer speculates that it could be due to poor heat dissipation characteristics. The stacked chips that make up the 3D Cache would make it difficult to cool the underlying chiplet, with which the refrigeration is already not uniform. This irregular cooling would mean that if overclocking is added, heat is added. AMD may not be confident that the various CPU hot spots can stay within acceptable levels of heat during overclocking.
The use of vias of silicon (TSV) to connect the cache on top of the regular Zen 3 chiplet is very advanced technology. AMD can build the chips to fit certain design parameters, but if a CPU goes out of base specification with higher voltages and currents, AMD may not be able to guarantee that the chips will not fail.
By now we know that AMD has lowered the clocks of the 5800X3D compared to the 5800X. The 5800X3D will come with a base clock of 3,4 GHz and a boost clock of 4,5 GHz. This is 400 MHz and 200 MHz less than the 5800X respectively. But the expected 3D Caché would allow it to solve this difference and equal or surpass the Core i9 12900K in some games.
