AI NOS/Overclock... how does it work?

[Guest]

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Is there any kind of FAQ, PDF, DOC, or whatever, that describes how the AI
Overclock and NOS works?

What happens when I set standard/ai nos/etc on "AI Overclock Tuner"?
What changes between auto/standard/sensitive/heavy load on "NOS Mode"?
What happens changing disabled/x% on "Turbo NOS"?

Is there any relationship between those items?

TIA

An Overclock Tuner would be a tool for static overclocking.
Set it to 10% overclock and it stays at 10%.

According to this link, AI NOS adjusts processor clock rate
according to the system load:

http://www.viperlair.com/reviews/cpu_mobo/asus/intel/lga775/P5AD2we/p2.shtml

"While the others are fairly self-explanatory, AI N.O.S.
is unique in that depending on your system load, the
motherboard will dynamically overclock. During this time,
the FSB and voltages will be adjusted automatically."

I had hoped to find info from Asusemag, but that appears to
be busted. I guess only resellers have access now.

Make sure you have a good power supply before overclocking.

Ok, thanks

It's ok... that means that when I select "AI NOS", the mobo auto-overclocks
to the percentage I set in "Turbo NOS".

But what's the difference between "auto" "standard" "sensitive" and "heavy
load" in "NOS Mode" item?

I've been searching for FAQ, manuals, PDF, or others. There's nothing :-(
And the manual says nothing as well :-(

I tried a couple of times, but I cannot go anymore than 5%.
If I try 7% the computer stops responding as soon as Windows XP comes to
the desktop.

These policies would have to do with when the computer turns up the
FSB and voltage. "Sensitive" implies that even if there is a
tiny blip in CPU loading, the BIOS turns up the performance.
Unless you can find a review article, I'm afraid you'll have to
use your imagination for what the others mean

I think you should find some Windows utilities (ones that are
known to read dynamic overclocks properly), and watch what settings
are used when Prime95 is running or when the computer is sitting
idle in the desktop. You might be surprised to find that the
Asus software/firmware is using some ridiculous setting.

For example, one other Asus product, turned up Vcore to a fairly
dangerous level. The thing about software based solutions, is
you as the user are not in control of the tiny details.

That is why, my opinion is, if you are overclocking, you should
set the BIOS to manual, set the FSB yourself, test with Prime95
for error free operation, adjust Vcore down until it becomes
unstable, then apply enough Vcore to make it happy again. Nothing
compares to a manually adjusted overclock, in terms of being
happy with the results. If you use dynamic overclocking, you
can never really be sure of the stability of the computer
while it is in transition from one FSB/Vcore setting to
another. At least with AMD, you know that the operation of
Cool&Quiet has been tested in the AMD laboratory, so you can be
fairly certain that there is design margin for the FID/VID
transition used. The AI-NOS feature of Asus, is only tested
by Asus and not by Intel. Since the algorithm is not described
in detail, only a couple designers in Taiwan know how good it is.

HTH,
