Chinese enthusiasts “overclocked” samples of AMD EPYC 7773X server chips to 4.8 GHz using 3D V-Cache technology

The Chinese social network Bilibili has published information about the performance of a system based on two Milan-X server processors from the AMD EPYC 7773X series with 64 cores and 128 threads and 3D V-Cache technology, which has not yet been released to the public became.

These processors are not yet commercially available and are only available to AMD OEM partners. However, the Chinese blogger managed to get two technical samples of this processor at once and test them on a SuperMicro motherboard with two SP3 processor sockets.

The system identified both processors as model 100-000000504-04, indicating they are engineering samples. The declared operating frequency range of the EPYC 7773X is 2.2-3.5 GHz. Technical samples, on the other hand, work at a frequency that is 100 MHz lower. Because of the 3D V-Cache technology, each of them has 768MB of L3 cache. A Chinese enthusiast tested the processors in the synthetic benchmarks Cinebench R23 and 3DMark. The novelty was faster than the Intel Xeon Platinum 8375C chip.

The Chinese tech blogger didn’t stop there. He decided to overclock the processors to 4.8 GHz. To do this, he used the utility AMD EPYC overclocking, developed by Uat4 enthusiasts and ExecutableFix. The program made it possible to significantly increase the power consumption limit of the processor, as well as the frequency. But it only works with engineering samples. According to the developers of the utility, this cannot be called real overclocking.

The developers of the application note that the processor frequency shown in the screenshot of the CPU-Z program (picture above) is not real after overclocking. It only reflects the desired maximum value. For this reason, the Chinese enthusiast did not provide data on the performance of the processor “overclocked” to 4.8 GHz in the same benchmarks.
