FAQs

Q: Which platform/socket does this CPU require?
A: It is designed for SP3 platforms supporting AMD EPYC 7003 (Milan‑X). Consult your server’s CPU support list and BIOS/firmware requirements.

Q: Does the large 3D V‑Cache help all workloads?
A: It most benefits cache‑sensitive and memory‑bound workloads such as EDA, CFD, FEA, and some analytics. Purely compute‑bound tasks may see smaller gains.

Q: Can I mix Milan‑X with non‑X Milan CPUs in a dual‑socket server?
A: Mixing different CPU models is generally not supported. Use identical processors per system and follow the vendor’s supported configurations.
