Figure 14-1: Memory Configurator
Note: The public release of the simulator supports no specific or non-symmetric DIMM
configurations. To change the simulated memory size please use the Memory
Configurator.
If you want specific or non-symmetric DIMM configurations please follow these steps:
1. Use “View→Show Devices” to show the Devices Window.
2. Right-click on the DIMM-memory device icon in the Device Window and select
the “Configure Device” option on the Workspace Popup Menu (Figure 3-3 on
page 11).
3. Select the tab for the DIMM slot that you wish to alter.
4. Click the Import SPD button and browse for an appropriate SPD file. The SPD
files should be stored in the Images directory. The SPD filename should give an
indication of the size of the DIMM that it represents.
5. A DIMM can be eliminated from the system, by changing the contents of SPD
byte 0 (Number of SPD Bytes Used) to zero.
6. Click OK to close the configuration property sheet and accept the changes.
14.3 Changing SPD Data
Any byte of SPD data can be altered in order to model DIMM configurations that do not
currently exist. The process for modifying a SPD data byte is as follows:
1. Use “View→Show Devices” to show the Devices Window.
2. Right-click on the DIMM Memory device icon in the Device Window and select
the “Configure Device” option on the Workspace Popup Menu (Figure 3-3 on
page 11).
