Help with BIOS options

post #1 of 4
Thread Starter 
Load-Line Calibration: Default is Auto

CPU and PCIE Spread Spectrum: Default is Auto

Intel VT-d: Default is Disabled

ACPI 2.0: Default is Disabled


What do these options do and what would I get from them?

CPU and PCIE spread spectrum should be disabled, and LLC can be disabled as well.

LLC prevents voltage fluctuations on your board but many a time hinder your overclocking abilities.

PCIe spread spectrum attempts to maintain a constant power feed across your PCI lanes. Disabling it really does not harm, and may indeed draw less from the socket.

The others may be generic terms slightly changed by your mobo manf. I am unaware as to their references. if you could give us the definition your mobo gives maybe then we could relate.

For the Spread Spectrums it says to leave on Auto for EMI control, true or false?

For Intel VT-d it says "Allows you to enable or disable the Intel Virtualization Technology for Directed I/O. Configuration options: [Disabled] or Enabled"

I can't find anything in the manual about the ACPI 2.0, I think it was introduced in a later BIOS version.

I would leave the spectrum off, you don't know how it may affect the Bus and the lanes themselves.

As for the Virtualization technology you can leave that on it has nothing to do with clock speeds.


Apparently, ACPI 2.0 is

"ACPI establishes industry-standard interfaces enabling OS-directed configuration, power management, and thermal management of mobile, desktop, and server platforms."

Hope this helps.
