Revision 1.0 

The following Integration and Usage Tips are provided to assist with answering miscellaneous 
questions about the Server Board SE7520JR2 or as a guide to assist with troubleshooting 
common errors. 

• 

The use of DDR2 - 400 MHz or DDR - 266/333 MHz DIMMs is dependant on which board 
SKU is used. DDR-2 DIMMs cannot be used on a board designed to support DDR. DDR 
DIMMs cannot be used on boards designed to support DDR-2 

• 

DDR-266 & DDR-333 DIMM population rules are as follows: 

A.  DIMM banks must be populated in order starting with the slots furthest from MCH 
B.  Single rank DIMMs must be populated before dual rank DIMMs 
C.  A maximum of four DIMMs can be populated when all four DIMMs are dual rank DDR-

333 DIMMs. 

• 

DDR2-400 DIMM population rules are as follows: 

A.  DIMMs banks must be populated in order starting with the slots furthest from MCH 
B.  Dual rank DIMMs are populated before single rank DIMMs 
C.  A maximum of four DIMMs can be populated when all four DIMMs are dual rank DDR2-

400 DIMMs 

• 

On the Server Board SE7520JR2, when using all dual rank DDR-333 or DDR2-400 DIMMs, 
a total of four DIMMs can be populated. Configuring more than four dual rank DDR-333 or 
DDR2-400 DIMMs will result in the BIOS generating a memory configuration error 

• 

The DIMM Sparing feature requires that the spare DIMM be at least the size of the largest 
primary DIMM in use 

• 

It is possible for a Memory RASUM feature to be initiated without notification that the action 
has occurred when using standard on-board platform instrumentation 

• 

A ZCR card is only supported on the full-height riser slot.  When installing the card, it MUST 
be populated in the PCI-X add-in slot furthest from the baseboard. 

• 

The Server Board SE7520JR2 has support for Zero Channel RAID (ZCR) which follows the 
RUBI2 standard. It will not have support for zero channel RAID cards that follow the 
RADIOS standard.
