BIOS features.

Under Platfrom Misc Configuration:

PCI Express Native Power Managment: Disabled

Enabled = Vista controls ASPM for the device
Disabled= BIOS controls ASPM for the device

What is the best option to pick. By default it is disabled.

I vote for leaving it on the default disabled setting. Is this your Z87 motherboard? I'm surprised it mentions "Vista" in the BIOS item.

Here's an M$ note on exactly what it does for you, or why it likely doesn't matter that much:

Yes, its on the Z87. It seems some companies do not update wording. And as we all know windows 7 is just vista matured.............
