Memory DDR4 DIMM (288 pin Dual-In-Line Memory Module)

DDR4 DIMM memory module (288 pin Dual-In-Line Memory Module). Physical dimensions and appearance of the memory module.

DDR4 DIMM memory module (288 pin Dual-In-Line Memory Module). Front and back side of the module, dimensions, numbering of contacts.

Pinout of the slot (connector, socket) of DDR4 DIMM RAM on motherboards.

• VDD is the memory supply voltage.
• VDDSPD is the supply voltage of the microcircuit that stores SPD data.
• VREF - reference voltage, usually equal to VDD/2. Usually formed by a resistive divider from the memory supply voltage.
• VTT - memory termination voltage is usually equal to VDD/2. For DDR4 SDRAM, due to the presence of internal termination, is supplied directly to the memory slot.
• VPP - memory activation voltage.
