'''EPYC 7251''' is a dual-socket {{arch|64}} [[octa-core]] [[x86]] enterprise server microprocessor introduced by [[AMD]] in mid-[[2017]]. This processor is based on the {{amd|Zen|l=arch}} microarchitecture and is manufactured on a [[14 nm process]]. The 7251 has a base frequency of 2.1 GHz with a turbo frequency of 2.9 GHz for all cores. This chip has a TDP of 120 W and supports up to 2 TiB of octa-channel DDR4-2400 ECC memory per socket.
