Abstract

A DIMM riser card that includes a PCB having a first edge, a second edge, and one or more faces. The first edge of the PCB is configured for insertion into a main board DIMM socket. The first edge includes electrical traces that electrically couple to a memory bus. The DIMM riser card includes an angled DIMM socket mounted on one face of the PCB, where the angled DIMM socket is configured to accept a DIMM at an angle not perpendicular to the PCB and electrically couple the DIMM to the memory bus. The DIMM riser card includes a straddle mount DIMM socket mounted on the second edge of the PCB. The straddle mount DIMM socket is configured to accept a DIMM and electrically couple the DIMM to the memory bus through the electrical traces on the first edge of the PCB.
