Memory Riser Card Population Rules

The memory riser population rules for the Sun Server X4-4 are as follows:

1. Each CPU has two dedicated memory riser card slots (MR0 and MR1).

2. The dedicated memory riser slots for each installed CPU must contain a memory riser card.

   • A two CPU system must contain four memory riser cards

   • A four CPU system must contain eight memory riser cards

3. When populating the server with memory riser cards:

   • First populate riser slot MR0 for each CPU, starting with the lowest numbered CPU (P0).

   • Then populate riser slot MR1 for each CPU, starting with the lowest numbered CPU (P0).
