Systems and techniques for vertical module connectors with pin-clamp mechanisms are described. An example module connector includes two cross-members, with each cross-member including at least one row of pins. Upon insertion, the pins are arranged to make electrical contact with pins on a memory module (e.g., a dual in-line memory module (DIMM)). The module connector also includes a clamping mechanism (e.g., a hinge assembly) that closes a first cross-member against or towards a second cross-member in response to or after insertion of the memory module. The module connector further includes a locking mechanism to maintain a closed state of the two cross-members and provide electrical contact between the row of pins on each cross-member and pins on the memory module. The described module connector allows for the insertion of memory modules with increased pins without reduced insertion force.
