Should i have the cpu volt on auto (1055t)?
On CPU-Z it says that i have 1.52 volt but on Core temp it says that i got 1.42 volt

Thanks!

Yes. Board voltages vary significantly. Some folks use undervolting successfully, but it can also cause instability. If your temps fall in the range of 35c-65c under max load, then you don't need to adjust the voltage.

When i have prime 95 on, i get two different temps,

Core temp = 54c

hwmonitor = 59c

Can i set the volt to 1.425(core temp says that) so it's not 1.52(CPU-Z says that)?



Thanks

see your cpu voltage through bios..
software monitoring sometimes not accurate..

How about speedfan? have you already try it..?
this is a really handy monitoring software, you have to try it.. :) 

Btw, my 1055T stock voltage is 1.275 volt ..
and 1.400v at 4Ghz..

What is your motherboard..?
actually default voltage vary depend on motherboard..

i have a ASUS M4A89GTD PRO/USB3.

All volts on different program

speedfan = 1.52
cpu-z = 1.52
core temp = 1.42 (and it has not change since i started the computer with 3.37ghz)
hwmonitor = 1.52

i think i should try to turn off auto and set it to 1.4, my CPU is getting kinda hot(61c). Or what do you think?

well, there are three software pointing same number, 1.52v.. :) 
i guess 1.52v is the right number.. (But you still have to check your voltage in bios..)

This is a little bit too high for phenom II series..

Okay..Question..
Did you overclock your cpu ?
and if yes, did you overclock it through asus software?

I overclocked from 2.8ghz to 3.37 ghz, i haven't touched the volt meter, (it's on auto)
I changed the bus speed from 200 to 240, no asus software.

If you reset your speed back to 2.8Ghz, how about your voltage..?
Still 1.52v or lower?

Try to reset your bios to original state, and check your voltage..

Ok, just a quick note, when i turn off prime 95(that has been running for 2.5 hours) the volt drops down to 1.488

November 4, 2012 5:31:43 PM

Checked the bios, on idle the volt is 1.488 volt (3.37 ghz)
on 2.8 ghz on idle the volt is 1.38
on 2.8ghz on full load the volt is 1.38 too.

Okay..then your default voltage is 1.38v. Then this is the base voltage of your processor..

Seems your motherboard raise processor voltage depend on fsb that already set..

Try this..


Set your HtClock to 1.6Ghz or 8

Set your cpu voltage (Vcore) at 1.38v manually, then increase your fsb to 240..
Check your stability with prime95 at least half hour..

If it stable enough, then decrease your voltage to 1.36/1.35v and check again with prime95
Or
You can set your fsb to 250 (3.5 Ghz), and check your stability..

Before you posted this i set the volt to 1.4 and ghz to 3.37ghz.
I'm testing right now and it's looking good, i'm going to lower the volt later.
It has lower by him self to 1.33 volt, and the temp is 49c!

typical vdroop of some motherboard.. :ange: 

if you set your voltage thorugh exact core vid for exp: 1.400, usually it will drop slightly..

but if you set through voltage offset for exp: +0.1, usually give more stable voltage..

try to set this
core vid: 1.3v
voltage offset: +0.1v

maybe it will give you more stable voltage than if you set your core vid manually to 1.4v.
