1. A method at a host device, comprising:
reading, by the host device, a value of a register comprising serial presence detect (SPD) data of a first memory module, the SPD data indicative of a timing constraint for operating the first memory module at a corresponding first clock rate, the timing constraint and the corresponding first clock rate associated with a first speed bin;
selecting, for communication with the first memory module, a second speed bin associated with a second clock rate at the host device and the timing constraint, wherein the host device supports operations according to a set of timing constraints that comprises a plurality of values, and wherein the timing constraint is selected from a subset of the set of timing constraints, the subset exclusive of at least one of the plurality of values; and
communicating with the first memory module according to the second speed bin.
