FIGURE 1
DIMM Bank Organization
Note –
Each DIMM bank being used must contain four DIMMs of equal density (for
example, four 64-Mbyte DIMMs) to function properly. Do not mix DIMM densities
in any single bank.
4. Locate an empty bank of four DIMM slots (two on the motherboard and two on
the memory riser assembly).
Note –
Fill additional DIMM banks in this order: bank 1, bank 2, bank 3.
Bank 0 is the default DIMM position for DIMMs installed at the factory.
Caution –
When you loosen the memory riser assembly in the next step, loosen
both of the assembly’s thumbscrews simultaneously to avoid damaging the
connector.
5. Using the short leg of the torque-indicator driver (part number 340-6091), loosen
the thumbscrews, then use your hands to turn the thumbscrews simultaneously
until the assembly is loose (
).
