Hello,<br><br>
just signed up as I saw this great site!<br><br>
I oc'd my P4 Prescott 478 from its original 3Ghz to 3.67Ghz without increasing vcore. My question is:<br><br>
1- Did anyone ever clocked 670Mhz (or more) out of a CPU without increasing vcore?<br><br>
2- My ram runs at 400Mhz and the next step of my p4p800-E Deluxe is 500Mhz. Could someone give me Ram timing for 500mhz?<br><br>
3- How can I change my oc multiplier to 14x or less? My Precott has the D0 stepping which is said that it can be run at 14x mplier.<br><br>
4- Does CPU Lock free work for my mb?<br><br>
Here my specs from oc's cpuz:<br><br>

Generally that CPU is very power hungry so it wouldnt be long until you need to raise the V-core.<br><br>
You cant Change the Multiplier in an Intel Cpu unless its an engineering sample...Sorry

All Asus has really done is to offer a BIOS version that enables the user to manually change processor settings from those that the processor otherwise requires. This way, the processor is literally fooled. As a result, it will only boot at multiplier x14 rather then x17 or x18 for the 3.4 and 3.6 GHz versions.<br><br><br><b>Source:</b> <a href="http://www.tomshardware.com/2004/09/16/asus_bios_unlocks_p4_overclocking_potential/page5.html" target="_blank"><b>Tom's Hardware</b></a>

S478 motherboards will not allow unlocked multi's on this chip.<br><br>
The D0 stepping CPU's will do ~4ghz whith a small increase in VCore ~1.50-1.55v (based upon a CPUVID of 1.40v)<br><br>
DDR500 (FSB 250MHz) would equate to 3.75GHz this is eaily obtainable but you may have to use the 5:4 memory divider to keep your memory at DDR400 if it does not overclock very well.

Hi,<br><br>
I run it for over a year already without raising vcore <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin">

I think he means if you increase the operating frequency any higher than it is now <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink">

I can even get higher then 3.75 but then it is not very stable. At 3.67 it is stable. Sry but what is CPUVID? I guess a bios option but not sure<br><br>
*added*<br><br>
Since i live in Thailand and here the temperature is allways around 30C-35C my rig runs very cool at 42C idle and 49under load. Not want to kill the CPU with higher vcore. Just thought to get the mem to 500Mhz...

oh alright... so do you guys can tell me how it is possible to OC a CPU 675Mhz without raising vcore? I started with an ZX81 about 24 years ago and went all the way to P4. Overclocked many CPU's but never without raising vcore. Or is that a side effect of 'strained silicon' ?

When a batch of CPU's are made the VCore of the CPU is determined. Each processor from the batch is assessed and a voltage assigned to it.<br><br>
Some processors require slightly more voltage than others to operate at the same speed.<br><br>
This means say out of 20 processors rated at 3.0GHz, for instance some will work at 1.40, others need say 1.45v. This voltage requirement is then tagged to the processor so that the motherboard knows what "stock" voltage is.<br><br>
CPU VID = CPU Voltage Identification <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink">

well just to let you know depending on what cooling you have you could easliy push the speed over 4ghz without it going oevr 1.45 voltage as i am overclocking at 4100 and my temp is only 33 'c

Press the "Prt Scr" button on the top right of your keyboard. Now go to Microsoft Paint and paste the screenshot with Ctrl+V. Save this as Jpeg format and upload onto this site <img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb">

AIBooster never works for me. It gives allways a strange error - even the latest version from Asus.<br />
<br />
Did you use Ai-Booster to clock to 4ghz with 1.45v or the bios?

ai booster and i had the same probem as u, get the ai booster from the disc not the one from the interent or you can get it from asus webstie for our motherboard just google it very helpful thats how im overclocking it so much i tried 4200mhz but it crashed

I wish I would still have that Asus CD - I lost it when I moved to another house - that version from Asus not works - what version is that AI Booster from the Asus CD? Maybe I can find it on the net
