Dell PowerEdge 6600 - Manual (Page 58)

When you install memory modules, follow these guidelines:
l Each bank must contain identical modules. You must install memory modules in matched sets of four, two in each memory riser card (see Figure 6 -9 ).
l Install identical memory modules in sockets A and B for bank 1 before installing modules in sockets for bank 2, and so on.
l Memory banks must be populated sequentially, which means that there can be no empty banks between the first and last populated banks.
Figure 6-9. Memory Module Sockets
Table 6 -3 lists several sample memory configurations based on these guidelines.
Performing a Memory Upgrade
1. Remove the memory riser cards (see " Removing the Memory Riser Cards ").
2. Install or replace the memory module pairs on each memory riser card as necessary to reach the desired memory total (see " Installing Memory
Modules " and " Removing Memory Modules ").
See Figure 6 -9 for the memory module socket locations on each memory riser card.
3. Replace the memory riser cards (see " Replacing the Memory Riser Cards ").
4. Reconnect the system to the electrical outlet, and turn on the system.
After the system completes the POST routine, it runs a memory test.
The system detects that the new memory does not match the system configuration information, which is stored in NVRAM. The monitor displays an error
message that ends with the following words:
Press <F1> to continue; <F2> to enter System Setup
5. Press <F2> to enter the System Setup program, and check the System Memory setting in the system data box.
The system should have already changed the value in the System Memory setting to reflect the newly installed memory.
6. If the System Memory value is incorrect, one or more of the memory modules may not be installed properly. Repeat steps 1 through 4 again, checking

NOTE: This table is a sample configuration of just one memory riser card. For the total desired memory, you must configure both riser cards identically with
the same memory module sizes.
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
" Safety First—For You and Your System " in "Troubleshooting Your System."
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
