AMD Confirms Ryzen 7 5800X3D Will Not Support Overclocking

A few days ago we wrote that AMD was supposed to disable overclocking on its upcoming Ryzen 7 5800X3D processor. This news has now been officially confirmed by AMD.

Robert Hallock, AMD Director of Technical Marketing, confirmed that the first Ryzen CPU with 3D V-Cache would not support core or cache overclocking during a interview with Hot Hardware (via VideoCardz). AMD says that Infinity Fabric and memory overclocking is still enabled and doesn’t rule out overclocking in future models.

In the video, Hallock explained that the voltage is no more than 1.35V. He goes on to explain that the technology is yet to mature and that it was developed with gamers in mind rather than overclockers. This makes sense as games are more likely to benefit from the extra cache. We wouldn’t expect miracles until the technology matures further.

The lower clocks and lack of overclocking support point to the 5800X3D being a niche product, likely with low production volume. AMD is ready to launch Epyc chips with V-cache, so what little manufacturing capacity there is is certainly being reserved for these high-margin models. It would also make sense for AMD to address the issues now, with what amounts to pilot production runs rather than facing any issues if or when Zen 4 CPUs with V-cache are released.

AMD is touting the gaming performance of the 5800X3D. The extra 64 MB of cache over the base 5800X’s 32 MB is reported to provide a up to 15% increase despite its lower 400MHz base clock and lower 200MHz boost clock.

The Ryzen 7 5800X3D is scheduled to be released on April 20th for $449. Only one of several new processors AMD is releasing in the coming weeks and months. They will likely be the last AM4 CPUs to be released before the arrival of Zen 4 CPUs later in 2022.
