System Memory
•
Four 288-pin Non-ECC UDIMM up to 128GB (Core™ i5/i7 only support
non-ECC)
•
Dual Channel DDR4 2400/2666/2933MHz (ECC support: W480E only)
Features
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits from the memory channels. DIMMs are on the same
channel. DIMMs in a channel can be identical or completely different. However, we highly rec-
ommend using identical DIMMs. Not all slots need to be populated.
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.
Before installing the memory module, please make sure that the following safety cautions are
well-attended.
1. Make sure the PC and all other peripheral devices connected to it has been powered
down.
2. Disconnect all power cords and cables.
3. Locate the DIMM socket on the system board
4. Make sure the notch on memory card is aligned to the key on the socket.
