AMD EPYC “Milan-X” in overclocking reaches 4.8GHz

A Chinese video blogger managed to get two 64-core AMD EPYC 7773X 'Milan-X' processors with 804MB of cache (per CPU) and not only tested them, but also overclocked them to an unprecedented frequency of 4.80GHz. .

However, as AMD prepares to formally launch its new products, the company is sending samples to dozens of its partners, which is why some specimens may end up in the hands of reporters or bloggers.

That's what it happened to the engineering samples of the AMD EPYC 7773X processor that were captured by the Chinese video blogger Kenaide (as reported by @momomo_us). The EPYC 7773X CPU champions are 64-core processors with a base frequency of 2.10 GHz and a boost clock of 3.40 GHz (lower than the commercial product's 2.20 GHz-3.50 GHz) and Milan-X's main feature is obviously the amount of 3D V-Cache on board, equal to 512MB. In total, the Milan-X 64-core CPUs have 804MB of cache in total: 32MB L2, 256MB L3, and 512MB 3D V-Cache.

Also, engineering samples tend to be limited; therefore, this could be another reason why the system has not impressed in some applications.

Kenaide, after having carried out the classic ritual tests, has also thought about how to overcharge the CPUs. Since server platforms are naturally not designed for overclocking, in an effort to increase the frequency of the AMD EPYC 7773X processors to 4.80 GHz (boost), Kenaide had to use a custom motherboard designed for hyperscale data centers and with a improved voltage regulation module. Thanks to the AMD EPYC Overclocking utility, he managed to increase the power limits to 1500W (from 280W by default) and the voltage up to 1.55V. Interestingly, the CPUs were cooled using air coolers, even though they ran at high speeds and therefore produced a lot of noise.
