Hello, guys

I just started overclocking yesterday.

Yesterday i bumped my 2.53 to 2.66 i will go farther today and the next day and so on.

But i was wondering, how do i know when its time to up my Vcore?

I have a Asus P4PE and for the Vcore in the BIOS it has manaul or Automatic. I have it on automatic does that mean it will up the vcore for me when its time?



Also for my memory speed i can chose
-automatic
-233
-355
-333

as my speed in my BIOS.

well my RAM in 333.. And now that im oC'ing those 3 optins are getting bigger. so should i chose one? or should i put it on automatic?


Thanks guys.
 
You need to give more detailed system specs if you want an accurate answer.

Your BIOS will not significantly increase the voltage to your CPU on its own. You have to do it manually. You'll know its time to increase your vcore when

a) You've OCed your system to the point of instability
b) You've got some headroom for cooling

For example, my PC will either lock up or reboot itself during games and I'll get prime95 errors if I run my Barton 2500+ @ 200Mhz FSB at the default 1.65v, but when I up it to 1.8v it runs rock solid, albeit much hotter.

When increasing the vcore you always run the risk of shortening your CPU's life, but if your OCing you will probably replace your CPU long before it dies anyway.
 
Ok here are more specs on my rig.


P4 2.53 (533) @ 2.66Ghz
1.55v @ 40C under load
Asus P4PE (Interl 845PE)
512MB Kingmax PC2700
PNY Geforce 4 Ti4200 (64mb) @ 270/540
Cooled By Koolance Exos
 
Rule of thumb is that P4's do not go over 1.7v (SNDS will occur at voltages higher than this), although i wouldn't be totally opposed to going higher, with good cooling. The memory settings are up to you. I'd personally keep it "automatic"
 
Ok thank you,

My temps will be dropping tonight. I think i made a boo boo when seting up Exos lol.


I filled it up with 100% Koolance Mix instead of 50/50 with distilled water.

ops :(

Tonight im going to drain half of my system and fill the remain part with disitilled water.

I am guessing this mix doesnt conduct heat as well as water.. OPS.

LOL.

So hopefully i will get it to drop atleast 5C tongight by fixing this.
 
Ops, nevermind. that pack was pre-mixed with distilled.

Damn :( i was hoping to drop a few more degrees.
