B650D4U B650D4U-2L2T B650D4U-2L2T/BCM Chapter 2 Installation This is a micro-ATX form factor (9.6” x 9.6”, 24.4 cm x 24.4 cm) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
2.3 Installing the CPU 1. Before you insert the 1718-Pin CPU into the socket, please check if the PnP cap is on the socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not force to insert the CPU into the socket if above situation is found.
Page 27
B650D4U B650D4U-2L2T B650D4U-2L2T/BCM Carefully place the CPU in as flat as possible. Do not drop it.
Page 28
Make sure the CPU is aligned with the socket before locking it into place. Make sure the black cover plate is always in place until it pops off when closing the socket lever. Please save the cover if the processor is removed. The cover must be placed if you wish to return the motherboard for after service.
B650D4U B650D4U-2L2T B650D4U-2L2T/BCM 2.4 Installing the CPU Fan and Heatsink After you install the CPU into this motherboard, it is necessary to install a larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU and the heatsink to improve heat dissipation.
B650D4U B650D4U-2L2T B650D4U-2L2T/BCM 2.5 Installing Memory Modules (DIMM) This motherboard provides four 288-pin DDR5 (Double Data Rate 5) DIMM slots, and supports Dual Channel Memory Technology. 1. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR5 DIMM pairs.
Page 32
The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.
B650D4U B650D4U-2L2T B650D4U-2L2T/BCM 2.6 Expansion Slots (PCI Express Slots) There are 3 PCI Express slots on this motherboard. PCIE slot: PCIE4 (PCIE 4.0 x1 slot, from FCH) is used for PCI Express x1 lane width cards. PCIE6 (PCIE 5.0 x16 slot, from CPU) is used for PCI Express x16 lane width cards.
2.7 Jumper Setup The illustration shows how jumpers are setup. When the jumper cap is placed on the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is “Open”. The illustration shows a 3-pin jumper whose pin1 and pin2 are “Short” when a jumper cap is placed on these 2 pins.
B650D4U B650D4U-2L2T B650D4U-2L2T/BCM 2.8 Onboard Headers and Connectors Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard.
