Voltage!!

[Iceman24680]

I was wondering how to give me more voltage so I can overclock more. right now under vcore it says default (what the hell is that?) so if ya can help me out that would be great thanks.

"Default" is what Intel thinks your CPU needs to run on to work. Usually, that is 1.7V or thereabouts for Coppermine chips. I have mine under default, but I have a peltier setup too. Try incraments of .05 volts first (go from 1.7 to 1.75, if that doesn't work, to 1.8, so on). G'luck, and may the MHz gods smile on you.

I know but i cant change the voltage the only selection there is, is default.

you will have to perform a "wire trick" on that cpu to increase your voltage, iceman, because you cannot change it in the BIOS. Be aware that when you do this, you will not be able to make any adjustments once the chip is in the socket, so take it up in small steps with the wire, and be absolutely sure that your cooling solution will handle to increase, or do not try this. I would hate to see you fry that chip. You may not be getting what you want to get, but so far you do have a successful, stable o/c of 100MHz...

*EDIT* I am not certain that you can do a wire trick if the BIOS doesn't support a voltage increase...better get some more feedback before attempting this...

Welcome to the forums...

What mobo do you have? If you can't change the voltage then your kinda out of luck... you won't be able to go REAL high as far as an overclock goes... but you'll be able to get somewhere I'm sure. My 750 did between 800 to 900 on default voltage (don't remember exactly)... but I had to up it to 1.85 (from 1.7) to get to 1000 stable...

Here's some info on the wire trick should you decide to do it:

For a coppermine CPU with the default voltage of 1.7v (if the default voltage is anything other than 1.7v then this will NOT apply), here are the pins to wrap:

VSS+VID0=1.75v
VSS+VID1=1.8v
VSS+VID0+VID1=1.85v
VSS+VID2=1.9v
VSS+VID0+VID2=1.95v
VSS+VID1+VID2=2.0v
VSS+VID0+VID1+VID2=2.05v

I wouldn't mess with more than two pins if it's avoidable, so 1.8V or 1.9V would be the best choices.

Good call guys... I didn't even think about that (never had a mobo that didn't support voltage adjustment).... Though it may seem a little risky if you refer to the chart that jazztrumpet posted... you should be able to go higher... just be careful as takiwa said... be a shame to fry your chip... just bump the voltage a little... and make sure you cooling can handle the heat... might want to put your fsb to the chips default and make sure the temps are ok with the increased voltage... then take the fsb up from there:D

Even though some boards have voltage adjustment, such as Tualatin boards like: Abit ST6 or the Asus TUSCL2. They can go further as for the vid pin your setting from 1.475 vcore default to like 1.575 etc

ok how do i connect the VID things?

[takiwa]

you have to loop a very thin peice of wire around them, and then twist it tight. There are several tutorials on the subject scattered throughout the forums, as well as a sticky here (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=59420). It's for a tualatin, so don't use those pins, but it willtell you how to wrap...
