Is memory overclocking possible on retail EPYC Milan?

[Methylzero]

As it says on the tin, does anyone know if it is possible to set higher DRAM speeds eg. DDR4 3600 on retail Milan CPUs? I seem to recall reading a post discussing tightening the timings, which is useful, but can the memory clock be increased?

afaik the Infinity Fabric clock runs synchronous with the memory clock in Milan.
means 1800Mhz Infinity Fabric clock with DDR4-3600. doubt that is possible stable operation.

Stability aside, it's just not possible to go beyond 3200MT/s. No bios lets you set anything higher. Assuming you somehow get your hands on a bios that is not capped at 3200, the retail CPUs are probably locked too.
