Vcore stability - Is BIOS stable or is MBM 5 wrong ?

Recommended Posts

In the process of o'cing my AMD 64 3700+ Clawhammer. (S.754)

 

At moment @ 2700 ( 225x12 ) - Vcore 1.595 v

 

MBM5 shows the vcore ( when set in bios @ 1.595 ) somtimes as high as 1.63/1.65

 

Questions :

 

Is MBM5 reporting correctly ?

 

Does the mobo regulate a steady / constant Vcore voltage ?

 

( As I dont want to fry the CPU ! )

 

 

Cheers.

(Sorry , sig needs updating , not a 3200 anymore)

With good cooling that voltage represents little concern of damage to that core. My 3700 has seen as much as 1.83 volts on peak but It was far beyond sustainable temperature there.

Ive asked this question 100 time never got one anwser my cpu take 1.7 no mater what i set the bios to under load. i tested every vcore combo in the bios three times wrote them down and only 1/4 if that change anything

Well, I know from experience that sometimes mobos will either pump extra juice to the CPU or take some away. I'd assume the extra juice is a BIOS related option that's intended to provide extra stability. If you're really worried you can lower your voltage in BIOS and then check in again via MBM5.

Thanks for replies.

 

The Vcore readings get more erratic the more voltage is applied

, but even at 1.5v idle the readings are 1.47 - 1.54 v

 

The question is are these voltage spikes actual or software/motherboard mis-readings ?

 

I dont want to be at 1.7v and suddenly jump to 1.8v and risk burnout.

 

Does anyone know how to measure the Vcore with a multimeter (if it's possible) ?

 

Cheers.

Same here, at 1450x110% mine will go near 1.65v, and now that is set at 1.55v, it will go high as 1.6v on load.

As pointed above, standard 1.5v reads 1.47-1.52v (idle/load). I guess only checking externally with a voltmeter can clear any doubt.
