Installing The Dimm Module - DFI CS331-C246 User Manual

CS331-C246/Q370
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits from the memory channels.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory channels. Dual channel provides
better system performance because it doubles the data transfer rate.
Single Channel
DIMMs are on the same channel. DIMMs in a channel can be identi-
cal or completely different. However, we highly recommend using
identical DIMMs. Not all slots need to be populated.
Dual Channel DIMMs of the same memory configuration are on different channels.
Features
• Four 288-pin DIMM up to 64GB
• The four DIMM sockets are divided into 2 channels:
Channel A - DDR4_1 and DDR4_2
Channel B - DDR4_3 and DDR4_4
• Dual Channel DDR4 2400/2666 MHz
