this one is for zenz. what is the maxium vCore for a barton 2500 that you think i safe, on air. and im talking about what cpu-z says ur voltage is. not set at in bios cause mine is like half a volt lower than what i set it at in bios. right now im at 2.03Vand scard to go higher,

I would say its up to your temps, if your getting over 50c load I wouldnt go much past that.

i would say 2.1 maybe 2.2 im at 2.06 in bios 2.03 in cpuz! an im running a 2500+Mobile stock Voltage on it is 1.45

Good point, I always go by CPU-z, maybe it's because it's a lower reading, My voltmeter on the mobo reads equally low from bios settings.So I feel it is more accurate.
Temperature, and stability are the key factors for me. I know I always try to run the lowest vCore needed for stability. You will have a hard time reaching high O/C's by setting the vCore higher than nessasary. I get the system to boot at a clock speed then add a tenth if it needs it for stability. More vCore than nessasary will hold ya back too. More voltz means more temp usually and lowers the headroom for O/cing.
There is no magic numbers to O/Cing ya just gotta see what she does and how she acts, if she's cranky or pissed or if she's getting along with the Ram and HDD, and sometimes shes happy...Happy is good!!
What makes the AMD-m line of Bartons O/Cers candy is the fact they are graded as CPUs' that will operate on the lower vCore as well as withstand higher temps..they are a 90C core.They are selected from the uber-prime part of the waffer.
Being unlocked is a plus too.
That's about as good as I can answer your question, and still be truthfull, nobody really knows till they blow, then you know that was too much...

yeah, thanks for ur help, i was startin to notice now matter how much higher i would go with volts i woudlnt realy gain stability.

Wait and let me get this straight.

You guys set the VCore in the BIOS, and you trust a third party software app to read your Mobo sensor more then the BIOS's own monitoring firmware ?

I think your out of your mind to do that. To begin with, how can CPUz even hope to be up-to-date with a new chipset release. All it takes is one time for you to get a new mobo with a new chipset, and CPU-Z read it wrong, and you have toasted a Proc.

Tell me I have the wrong angle on this.

that is correct, i do, just like wen ur bios is bootin up it reads ur overall cpu speed slower than it realy is

Sorry Bob, but mine boots so fast I can't read what it says

I would never trust some outfit like that. Not CPU-Z, MBM5, or any other.

BIOS is king with one honorable mention;

Temps, because some chipsets idle the CPU when in BIOS, and some load the CPU when in BIOS.

thats kinda tru but u got to think. when your bios says your temp is 34 is it ? than u look on your temp monitor an it says 40 ? what do u beleave? i would go with the temp monitor! But my bios does load my cpu!

Temps are king here, if you have a good way of reading them, then the that is your only hold back. Ive had mine cranked up to 2.125vcore so it would say 2.100vcore on boot up.

Im with you on this one lc, when I had my ol' PSU CPUz couldnt read my vcore correctly, I would have it set to 1.8 in my bios and it would say it was 1.6 in CPUz.

this is why i beleave the cpu-z! we all know that the NF7 under volts right?? ok so in my bios i put the Vcore at 2.125 ok now on cpu-z it reading 2.06! but once again we know that the NF7 under volts !

My issue is that a setting is just a setting, it doesn't mean that your going to get what you ordered.

Now I have seen BIOS updates that stated that xyz version was reading something wrong. So I am sure it happens. But I am also equally sure that CPU-Z can't possibly stay up to date with new chipsets faster then the manufacturers themselves. So as a rule, I would be looking at the BIOS first, and an easy confirmation or monitoring from third-party apps.

Hell, if I noticed a discrepency, say with voltage monitoring in MBM5, I would be much more inclined to adjust the MBM5 monitor .5v or whatever to make it read and match the what the BIOS says then I would to discount the BIOS and simply accept MBM5, or CPU-Z for that matter.

your not understanding what im saying tho. i dont trust mbm5 it sucks its wrong an we all no it ! but cpu-z tho is a great app an i do trust it alot!

I agree that it is just a setting in BIOS but when it comes to actual, I put the voltmeter to the mobo directly and on my NF7-S what I get on the mobo is always less than what bios says. They are built with voltage regulation and my PSU delivers within spec. So I am inclined to belive bios are written with a margine of saftey, irregaugrdless like I was saying stability and temps will dictate the voltage if you use it only if you need it and your temps allow for it.

Edit: now if I can get Twizted to set me up some of that active voltmeter sweetness, that I can solder in place on the mobo, and have full time at a glance, voltages,
I'd feel alot better about the possibilty of overvolting, and I would like to see the busses in action and if the stock regulators are keeping up.
Been seeing some guys increasing capacitor specs and it is helping smooth out the power. They are able to get stability in their godlike O/C's that they wern't able to get on the stock capacitors.

Roger Zennzzo, but Mattspc. I am not speaking specificly of MBM5, that was an example because I know that app allows you to set a variance adjustment, say if you beleave your CPU temp is 5C higher then what it is reporting, you can set a +5C adjustment for the displayed temp.

As for CPU-Z, I don't trust it at all. I much prefer WCPUID over CPU-Z. I have seen too many complaints of CPU-Z bouncing all over and being inaccurate.

But in the end, as I said before, any app must be up-to-date, and no app will be as up-to-date as original manufacturer. This is what so many of our noobs do not understand. They see everyone using something, or talking about something, and they just dive right in without knowing the groundwork or background behind things or how they work.

Just like right now, respected guys say they have absolute confidence in CPU-Z, they grab it. Next week they buy the latest and greatest Mobo going, and it happens to have a new chipset with new monitoring chips and firmware. This noob loads it up, puts all the pretty HSF, CCFLs, etc inside. All happy he loads up CPU-Z for a little overclocking and sees his voltage is low so he bumps it up and fries a new $300 Proc. So just where does that leave him ?

I do use these Apps, but I do not trust them and before I make adjustments based on their readings I look hard at everything I have available in order to make a determination on what I should do.

So this is what I am trying to get accross

good post good post ! i understand what u are saying. but in My situation cpu-z is probably on the dot i have a NF7-s v2.0 an i know it under volts right now im running a 2.0Vcore but i know my NF7 undervolts a lil Cpu-z says my Vcore is 1.92 so its porlly dead on! not sure but it works for me !

ahh, ive created a monster. lol this post has evolved into a contest between software apps and bios.

YES...
true, so abosoluty true.
I myself often forget, not everybody thinks alike...
**wonders if I should post a liability release**:wink:

Hehehehe It was the power supply not me I SWEAR. I didnt kill that proc it was a damn power spike hehehehehe......O wait WOOOPPPPPPS

Anyways, what I was gonna say was that even if you check in the mobo health page in your bios it will say that the voltage your getting isnt what you have selected. It never works like that, for some strange reason. Thats why when I do burn in I crank the voltage up past 2vcore like 2.050vcore so that way it will show it as 2vcore (as suggested by our burn in master Zen).

As for the growing debate here that can go another 3 more pages, I say we each use are own methods. What ever gets ya there, with your O/C and keeps your CPU from being fried use it. We each have are own methods of checking our temps, vcore etc....and we dont have to fight over it when someone knock's are method. If you havent fried a proc yet, I say continue using your mething as long as your happy thats what matters, and that your getting results.

There I said it.

i mean i dont know to much but am i wrong?
