4 installing the memory 29
Read the following guidelines before you begin to install the memory make sure that the motherboard supports the memory it is recommended that memory of the same capacity brand speed and chips be used always turn off the system and unplug the power cord from the power outlet before installing the memory to prevent hardware damage memory modules have a foolproof design a memory module can be installed in only one direction if you are unable to insert the memory switch the direction 29
This motherboard provides 24 ddr4 memory sockets and supports six channel technology after the memory is installed the bios will automatically detect the specifications and capacity of the memory enabling four channel memory mode will be four times of the original memory bandwidth 29

4 4 dimm population table 31
4 5 intel optane dcpmm dimm population rule 32
Rdimm dcpmm must be installed into cpu0 memory first you must install one rdimm into any slot 0 of cpu0 before installing the dcpmm e g a0 b0 c0 d0 e0 f0 the dcpmm must be installed into the dimm slot 1 next to the corresponding rdimm in slot 0 e g if rdimm is installed into dimm slot a0 the dcpmm must be installed into dimm slot a1 32
System hardware installation 32 32
Thermal conditions for dcpmm dimm support the ambient temperature must be at or below 35 c the cascade lake cpu used must have a maximum tdp of 205w a maximum of 12 pcs 256g dcpmm may be installed 32
