What is the Default MCH and FSB Voltage on D975XBX?

I have searched, searched, and searched and cannot find anything.

For the love of the children - Can someone PLEASE tell me what the default voltages are for the MCH and the FSB on a D975XBX?

I'm running the gear in my rig and I'm runing into problems getting past 3.36 ghz. I've got the CPU at 1.400 but I want to adjust the FSB and MCH, there is just no literature on indication in the bios or IDCC about what the default is..

Please help before I loose the little hair I have left.

svirf.

PS: Thank you.

The defualts are the lowest selections you can make in the BIOS...I can't remember what they are specifically...I run mine at max, but make sure you have good case ventalation an active cooling on the N/B heatsink
