DDR4 DIMM Specification - DS1013

A single 288-pin DIMM socket is present on the V80 card. Certain card SKUs have the socket populated with a 32 GB DDR4 DIMM module (see Table 1). The following table details the populated 32 GB DIMM module. Power to the DIMM is enabled on the V80 when the card is powered on and must be initialized upon power-on. Power to the DIMM can be disabled via the I2C if the DIMM interface is not utilized.
