Auto Detect DIMM/PCI CLK
To reduce the occurrence of electromagnetic interference (EMI), the BIOS detects the presence or absence of components in DIMM and PCI slots and turns off system clock generator pulses against empty slots.
Spread Spectrum
When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus reducing EMI. This benefit may in some cases be outweighed by problems with timing- critical devices, such as a
10.10 Load Optimized Defaults
When you press <Enter> on this item, you will get a confirmation dialog box with a message similar to:
“ Load Optimized Defaults (Y/N) ? N ”
“Y” is for “Yes”, and “N” is for “No”.
Pressing “Y” loads the BIOS default values that are factor settings for optimal performance of system operations.
