When you select Disable, you can manually set up DRAM options.
Attention: Unless you are very familiar with your computer and with the
DRAM configuration and speed, we recommend you not
change the DRAM options but enable this option.
DRAM settings:
The other DRAM settings are all closely related to hardware. If you do

Memory Hole At 15M-16M:
This option is used to free up the 15M-16M memory block. Some

Disable: Disable memory check feature

Auto: Automatically enable or disable memory check feature. If your

feature.
