Auto Detect DIMM / PCI Clk

This BIOS feature determines whether the BIOS should actively reduce EMI (Electromagnetic Interference) and reduce power consumption by turning off unoccupied or inac- tive expansion slots.

When enabled, the BIOS will monitor AGP, PCI and memory slots and turn off clock signals to all unoccupied and inactive slots.

When disabled, the BIOS will not monitor AGP, PCI and memory slots. All clock signals will remain active even to unoccupied or inactive slots.

It is recommended that you enable this feature to save power and reduce EMI.

The choices are:

Enabled / Disabled

Spread Spectrum

This BIOS feature allows you to reduce the EMI of your moth- erboard by modulating the signals it generates so that the spikes are reduced to flatter curves. It achieves this by vary- ing the frequency slightly so that the signal does not use any particular frequency for more than a moment.

In most conditions, frequency modulation via this feature should not cause any problems. However, system stability may be slightly compromised in certain situations. For exam- ple, this BIOS feature may cause improper functioning of tim- ing-critical devices like clock-sensitive SCSI devices.

Spread Spectrum can also cause problems with overclocked systems, especially those that have been taken to extremes. Even a slight modulation of frequency may cause the proces- sor or any other overclocked components of the system to fail, leading to very predictable consequences.

Therefore, it is recommended that you disable this feature if you are overclocking your system. The risk of crashing your system is not worth the reduction in EMI. Of course, if EMI reduction is important to you, enable this feature by all means

The choices are:

Enabled / Disabled
