multiplier is 16 x that by the speed U want to go mine 16x225=2600 @ so on
Dram to MHz thats if you have PC3200 ram and that will give you 1.1
DRAM Frequency
AGP/PCI set to i think 33/66 is that right?
I have mine 3.2 modestly oc ed to 3.6with everything set like up above
i dont think i got that (overclock tuner) option.. eventhough its the same brand.. anyways, thanks.. i would like to get to 3.6 like yours but theres the heat prob with the 'standard' HSF..

well.. its 4.26MHz and 3.55MHz.. i forgot to mention that..
should i increase r\he ram voltage?

Set the DRAM Frequency to 3.55 to force it to run slower then your FSB.

You can also try setting it to auto and then check CPUZ to see what divider that sets.

Once you've set your RAM to run slower then your FSB, you can continue trying to raise the FSB and your RAM will no longer hold you back on overclocking.

However:

-Watch out for your temps (below 65° - below 60 is preferred) As said numourous times before.

-By the judge of it, you haven't raised your Vcore (CPU voltage) yet?
This might be what's holding you back, as raising the FSB will require a raise in voltage.
Up the Vcore a notch and try again.

BUT : Raising voltages = raising temperatures so again, watch out for that
And don't raise your voltages too much.


EDIT: didn't see you sneak in there Redmonster ^_^
should i set the FSB higer than the RAM speed? becuse ive read somewhere in this forum that its better to set it 1:1..

how to raise the vcore up one notch when theres only eneble and disable?
thanks all..

uhh no, wouldn't increase the Ram voltage if it runs fine.

(if your RAM holds you back, you could try upping it a bit,- otherwise leave it)

While it's true that 1:1 is the best ratio you are sometimes forced to set it to something like 4:3 when your ram cannot follow up anymore but your cpu can still take it higher.

In your overclocking options you should have the option of raising it. It should be called "VCore" or something like that.
Start by raising it in baby steps (about 0.0125V at a time) just be sure not to go over 1.525V and keep watchin those temps ! When you raise the cpu voltage the increase in cpu temperature follows a squared curve... not a straight proportional line so be careful.

** Edit: I just checked your mobo for you. Download the manual here and go to page 65 once you have the PDF file.
I stand corrected... there actually is an option called "CPU Vcore Over Voltage Control" as you said.
However I think this option, when enabled, allows the mobo to protect your cpu from inadvertently getting more voltage then it should. It does not appear to allow you to manually set the desired CPU voltage.

okey.. thanks..
so, if i cannot set the voltage on my own, why should there be the voltage control?
how can the voltage increase if nobodys doing it manually?
hmm.. is there any tips on how i can tackle the heat problem with only the intel fan? (currently going 3.37GHz only! with the temp 38C..)
is it normal for this chip to go 55C at 3.44GHz?

I'm guessing your mobo might slightly increase the temp if it has an auto overclock option. But that's just a wild guess... so nevermind that.

Unfortunately Intel's stock heatsink+fan were not designed with overclocking in mind. Prescott cpus are well known for running hotter than older Northwood Pentium 4 cpus.
However, I still think that 55C for a mere 2.44MHz increase in cpu speed is a bit high. Unless you're talking about load temp. (the temperature of your cpu when it's running at its full capacity or 100%).
I increased my cpu speed from 3.0 to 3.4 and idle/load temperatures barely increased from 36/52C to 39/56C. Mind you, I'm also running on Intel's stock heatsink+fan.

What's your room temperature ? How many fans do you have installed on that case of yours ?

Actually, I second that wild guess
Seriously, I read about it somewhere and it's probably a function of your Asus mobo which auto ups your Vcore.

With that in mind.. keep an eye on what your Vcore is set to with CPUZ, 'cause it should stay under ~1.5 volts

its 60C at full capacity..
i only got 2 casing fan but usually i open the side casing door..
is your P4 3.0 a prescott core too?

is it normal for the fan to go around 1880rpm(under 2000rpm) at 40C? because my friends cpu is 4000rpm at 25C!! (AMD)
