Can i get a tip from some experienced cpu overclockers?

post #1 of 14
Thread Starter 
When fine tuning an overclock i always try to get all the voltages as low as possible as im sure most people do. What im wondering though is does it make sense to bump up, say, the Vcore by one increment from the lowest stable voltage for said overclock? Do any of you guys do that or anything similar because you feel it gives a touch more stability/headroom, or do you think its just plain pointless? Thanks thumb.gif

If its stable, its stable. Adding a touch more might not hurt, but I don't see a need for it. Unless you have stability problems and then.... this kind of circular logic could go on forever.

yeh i pretty much thought of it like that. but i was wondering if that same logic of where ideally you build things to be a bit stronger than what you think is needed just to be sure, is relevant to this scenario. i figured you would have to have had years of experience to know about something like this so thought id try and round up the opinions of people in the know! maybe i should make this a poll tongue.gif thanks for the reply.

That is normally what I do. However I never stress test.

I get the voltage as low as possible while being stable and yes then I bump it a notch. Sometimes when the usage of cpu is jumping up and down violently rather than staying at 100% it can fail so I give it that extra little bit of voltage to compensate smile.gif

so there are others who think this is a good idea! i feel like if im at the lowest possible voltage then im right on the edge of instability (though i know higher voltage doesn't always = more stability). i think i'll probably keep running with this logic (unless anyone can come up with a good reason not to?) as +0.005v over the minimum stable isn't going to cause any crazy differences in heat or anything like that, and it gives you that peace of mind rolleyes.gif

If you're stable when stress testing, you should be stable at all other times as stressing uses a lot more CPU resources (for a longer period of time) than any other task. So in general, if you stress it overnight and it doesn't have any problems, you don't need any more voltage. You're just paranoid :-)

I do this because I fold on my cpu. Folding can sometimes crash after a 24hr prime blend I've found. thumb.gif

Yep, definitely paranoid.

Get your peace of mind by stress testing it within reason, if you've done that and then still want to bump it up .005v then you're really paranoid biggrin.gif

yeh i can't really argue much with that. its what i've been doing up until yesterday when i had this thought. i was just thinking that the little bit of extra voltage could be a sort of buffer/safety zone for any anomalies/abnormalities that may occur. i agree though that you shouldn't worry to much about it if you've passed a lengthy stress test! i usually leave prime running a blend test over night for at least 8 hours to test. the cpu in my computer wouldn't normally get worked that hard for so many hours on end so it should be fine right, but still i always try to find out the little things like this rolleyes.gif

Edit: Also thanks for confirming im paranoid guys ph34r-smiley.gif lol

@danielwiley - Yeh ive heard that folding is a good way of testing. i like using prime though because it tells you if one of the workers made a mistake as it already knows all the correct answers to the problems. wouldn't wanna be giving false calculations when folding either right :/
