AMD “Milan-X” 7773X EPYC CPUs with 3D V-Cache get overclocked to 4.8 GHz

Chinese Bilibili content creator ‘kenaide‘ goes through the overclocking process of AMD’s newest EPYC CPU. And yes, you read that right kenaide took a data-center EPYC 7773X 64-core and 128-thread processor for a quick overclocking session on a SuperMicro dual-socket motherboard. While those processors are currently only shipping to OEM partners and they are not yet officially on sale, the overclocker somehow found a way to obtain not one but two samples of such CPUs.

 

According to the video he posted, EPYC 7773X is being detected as 100-000000504-04 CPU, which is an OPN core for the AMD engineering sample. Officially this processor has a base clock of 2.2 GHz and a boost up to 3.5 GHz, but the engineering sample is running at 100 MHz lower clocks respectively. The EPYC Milan-X series are the first to feature 3D V-Cache technology, a special layer of L3 cache right on top of the compute dies. The EPYC 7773X is equipped with eight chiplets each featuring an additional 96 MB of cache. In other words, each CPU has a total of 768 MB of 3D V-Cache.

Using Curve Optimizer and CoreCycler, we should be able to verifiy the 12h prime95 stability of the OC in 768hours 🙂.

 

👆 An attempt at humor, please don't remind of the differences between Ryzen and EPYC :misc_zipped:

Cmon EVGA we need Evga Sr-2 Reborn 😆

 

2.8k-10k per cpu 

 

Wonder if game will ever utilise that much core. It like gpu the more core you have the higher resolution you need to benefit from it.

Those cpu are only good for entreprise use or game server.
