BIOS Option Of The Week — Virtualization Technology
Since 1999, we have been developing the BIOS Optimization Guide, affectionately known. Read here
Disable Unused PCI Clock
Common Options : Yes, No
This BIOS feature determines whether the BIOS should actively reduce EMI (Electromagnetic Interference) and reduce power consumption by turning off unoccupied or inactive PCI slots.
If you set it to Yes, the BIOS will monitor PCI slots and turn off clock signals to all unoccupied and inactive slots.
If you set it to No, the BIOS will not monitor PCI slots. All clock signals will remain active even to unoccupied or inactive slots.
It is recommended that you set this feature to Yes to save power and reduce EMI.

Disable Unused PCI Clock
Позволяет уменьшить уровень электромагнитного излучения компьютера. При ее включении перестают подаваться сигналы на неиспользуемые слоты шин PCI (и, возможно, PCI Express). Поскольку уменьшение уровня излучения незначительно и не оправдывает возможные проблемы со стабильностью работы компьютера, эту опцию лучше выключить (No), особенно, если вы занимаетесь разгоном.

«Unused PCI Slot Clock» What is it?
I’ve been trying to find more info about this option, but I can’t really find anything.
Can somebody please explain to me what it does?

Is anyone enabling this option now? I tried it in an early bios and it wouldnt boot. I’ll have to try enabling it again with 1.4.
