How does the Auto setting work on the Voltages (Vcc, Vnorthbridge, Vtermination voltage etc)? If pushing the FSB freq upwards, will the Auto setting raise the voltages as much as it need to work, even above dangerous levels? Or is there a "safe limit" for the Auto settings?
 
It's not very smart, as it's just an equation programmed into the BIOS and has nothing to do with whether or not anything actually works. IMHO it's more dangerous than useful.
 
Why don't you just download the data sheets from intel.com to know the maximum allowed voltages for the chips and use ASUS PC probe II to see if the auto settings go over them or not.
Personally I don't think so. Auto settings in ASUS's bioses are safe. On the other hand they don't raise the voltages high enough to reach stable high clocks. If you want to push your CPU and mobo to the limit, you'll have to change the CPU and NB voltages manually. Keep an eye on the temps though. If you need it, thermaltake extreme spirit II is a good cooler that fits for all NBs.
 
Ok, I was just curious. I have a Zalman CNPS9700AT, and right now my E6400 works at 3GHz, 44 degrees under load and no auto-settings. But what made me ask was that I can go 3GHz on Auto settings which was a little surprisning to me.
 
I could make my E6750 (Default:2.66 Ghz @ 1.23v) run at 3.2 on auto settings. Auto settings of my ASUS P5KSE set the Vcore to 1.34v...However 3.6 Ghz became stable only after I manually set it to 1.44v (1.40 after V drop). But before I started manual manipulation I dlled the data sheet of E6750 which stated that 1.5v is the maximum allowed voltage, 3.6 is the max frequency, and 65C was the max recommended temp for long term operation.
Short version: Unless you are an experienced extreme overclocker, stay within the specification limit of the chip to be on the safe side when you overclock.

Certainly 10 minutes to download a data sheet and read it isn't asking too much.
 
Yeah, but I searched the Intel.com and couldnt find the document you refer to. Could you please tell me what Im searching for?
I was looking at www.processorfinder.intel.com but there I only find info about temps.
 
Now that I visited the same page I visited 5 months ago, I just remembered that your E 6400 and my E 6750 share the same specifications as they are both conroe.
In the same link I gave you the specifications tab does not list E6400, probably because it has been discontinued (?). You 'll have to make do with the PDF data sheet.
