Memory costs remain an unresolved risk for Dell even after a quarter that proved the pre-earnings bearish lean wrong. Gross margin rose to 20.9% from 17.8% and the October quarter was guided to $49.0bn, but AI server revenue grew just 1.7% while backlog jumped to $95bn, so a mix shift toward traditional servers and storage flattered margin. The $74bn full-year AI target needs about 26% sequential AI growth, so memory costs hit the October quarter on a richer AI mix, still unquantified. x.com x.com
