Intel SE7520BD2 User Manual

Server Board Features
8
In a mirrored system, the maximum usable memory is one-half of the installed memory, with a
minimum of four DIMMs installed. Since the data is duplicated across DIMMs, it means that up to
four DIMMs are actively in use at any one time. If six 2 GB DIMMs are installed, the maximum
usable memory is 6 GB. The remaining three 2 GB DIMMs are used for mirroring.
For memory on-line sparing, one DIMM per channel is used as the memory spare. If a DIMM
begins to fail, the content of the failing DIMM is copied to the spare DIMM in that channel. When
all of the data is copied to the spare DIMM, the primary DIMM is removed from service and the
spare DIMM takes its place.
When memory on-line sparing is used, the spare DIMMs must be equal to or larger than the largest
in-service DIMM in that channel.
For additional information, refer to the Intel® Server Board SE7520BD2 Technical Product
Specification.
Power Supply
A minimum of 600 Watts is required. The power supply must provide a minimum of 2 A of 5-V
standby current or the board will not boot.
