Greetingz everyone,
I got an Asus P5Q Turbo installed into my rig 2 days ago.
>>>ASUS P5Q TURBO

Nice board OC'ing my E7400, with its 8-phase power design, pretty alright HSF on the NB and on the mosfet, a p45 chipset, I'm more confident to apply the OC config. of 3.8ghz/4ghz for 24/7 usage compared to my previously owned P5QL Pro(which seems to me is an entry level OC board) in which I wasn't confident enough regarding of how it will affect the life longevity of my OC'ed E7400 for 24/7 usage, when using that board.

Anyways is/are there any P5Q Turbo user(s) here?
Hope you guys can share with your experience with this board

I gotta say, the TurboV feature can be pretty handy when you want to fine tune(tweaking an increment or two)the voltage in real-time, then when I'm satisfied with the tweaking I can restart the comp and set the value in the BIOS. I only recommend TuborV for fine tuning(finishing touch) though...full-time OC activity/operation only done in BIOS

More details:

With this board, I manage to OC the E7400 @ 3.8ghz with 1.295v (cpu-z) with most of the other voltage mod to Auto or default settting (Asus specs),
yep, not that thrilling of an OC experience....but OC'ing the proc to 4ghz is a different ball game bcoz it gives me a hard time...manage to stabilizes it @ 400fsb x 10 @ 1.4v, which is an unsatisfactory result bcoz I bump the vcore on an unhealthy level(above 1.3625) for a 45nm chip...
ATM I'm eager to figure out other methods to achieve the magical 4ghz but maintaining the vcore well below 1.3625v, or least not more than 1.39v...

Nice motherboard btw bro Beautiful heatsink.
You know, OC'ing is a journey or a path once you got hooked up, you'll be addicted and will spend hours in pursuing perfection in terms of getting the most out of your system.
So as I have summed up, you should start fully educate yourself in Overclocking since it consist of few 'chapters' in which you need to master and countless knowledge which are prominent to acquire first before fiddling around with the TurboV.
Good news, there's plentiful of sifus on LY.net and its easy to start-off...but the challenging part is that little-lest of tweaking when you reach the OC limit of your system.

Other reasons people overclock is that for example, you can turn a2.8GHz RM400~ish processor (e.g. E7400) into a 3.6Ghz plus RM600+~ish processor

As for the TurboV (my new favourite toy) is only for tweaking bro, you should overclock full-time in the bios

E8400 can easily be OC'ed to 4ghz.
But first let's try to stabilize @3.6ghz, that's 400FSB X 8 (multipliers).

First, what was your Vcore when you OC it at 3.52ghz? By any chance you leave the Vcore on AUTO settings right?
Don't bother about NB and SB voltage yet, they are for maximum tweaking when you've reach 4ghz+. So rule them out first, to stabilize OC, you only need to primarily focus on the Vcore.

DOWNLOAD and install RealTemps before attempting any OC'ing:

You'll need this to monitor the CPU temps. (THIS IS NEVER TO BE TAKEN LIGHTLY)

Bro, first set your settings below, this is a basic starting point for Ai Tweaking ASUS board for 3.6Ghz:


As you can see, I didn't included the Vcore yet,because every proc is uniquely different to one another. Once you set those settings aforementioned above, let's play with the CPU voltage

First rule of OC'ing a 45nm chip is to not exceed more than 1.3625v, so there's two ways of methodology of doing this:
1) To start from 1.35v and running OCCT or Prime95 while going down an increment at a time until you will reach the most lowest stable Vcore.
2) To start from 1.28v and running OCCT or Prime95 while going up an increment at a time until you will reach the most stable Vcore.

------------------------------------------------------------------------------------------------------------------------------------------------------------
IMPORTANT NOTES:

For method (2), if you get it stable from the get-go @ 1.28v, you should run the stress test while going down an increment at a time until you will reach the most lowest stable Vcore.
Why? Simple logic, if you can stabilize it @ 1.28v, why go up since your primary goals is to find the lowest stable Vcore for OC, as far as 3.6ghz is concerned.

For method (1), if you couldn't get it stable for the get-go @ 1.35v, the only way is upping the increment one at a time. NEVER go more than 1.4v,
stabilizing 3.6ghz doesn't require that much voltage to start with, but just in case if you do happened to reach that point.
------------------------------------------------------------------------------------------------------------------------------------------------------------

~And why you ask 3.6ghz?
3.6ghz is considered moderate OC'ing for the E8400, very good frequency to first learn how to start OC.

~Ai Clock Twister, Ai Transaction Booster, NB & SB voltage, PLL voltage, FSB termination voltage, CPU GTL ref,etc.?
These are the 'Second' and 'Third' Phases of OC'ing, now you are working out the 'First Phase', that is to find the stable Vcore at any given CPU frequency. (3.6ghz for now, no more than that)
So you'll be playing around with those aforementioned settings when you'vee mastered the art of stabilizing the the CPU ferquency. (ghz)
As for now, totally ignore those settings, or else information overload will get you nowhere.


OK bro, find a whole day free and get cracking!
i) Before you start, install Realtemps and memorize the CPU LOAD's highest temps.(RUN prime95 for couple of minutes to acquire the highest LOAD temp.)
When running prime95, safe load temps is around 55c ~ 65c.
When you've done that, lets proceed to the next step.

ii)Select one of the two methods I provided above, (1) is quicker, (2) is conventional.
When running stress test on 3.6ghz, YOUR EYES MUST FOCUS ON REALTEMP FIRST to see if it reaches up to 70c..which is unrecommended.

For method (1): Let prime95 run minimum 3 hours, if stable then move the Vcore downwards by increment until you encounter errors, then up by an increment and run prime95 for more than 6 hours this time.
For method (2) Let prime95 run minimum 3 hours, if unstable then move the Vcore upwards by increment until you don't encounter errors, then run prime95 for more than 6 hours this time.

iii)When you have pin point the lowest stable voltage for 3.6ghz, run prime95 for as long as you possibly can (8-10 hours is more than enough, but longer is recommended)
This is for the final validation that the OC is perfect and successful.


Alright bro, I hope a appreciate this basic schooling in Overclocking: Chapter 1 - CPU Stabilization
Read my post thoroughly ya
