MCX75310AAS-NEAT - Re-marking IC chips

Is it common to have re-topping Winbond / Macronix chips on Mellanox cards ?

Hello,

Upon checking, this is not common or standard. NVIDIA HCAs are manufactured with authentic components, directly sourced from trusted suppliers.
If you suspect an issue here, please contact enterprisesupport@nvidia.com and this will be handled based on entitlement.
Thanks,
Jonathan.
