cpuZ-CPU VID - Page 4

post #31 of 43
BIOS should in theory always be more reliable than a software reading. Software can only screw up what the BIOS reports, it can't invent a new place to read the voltage from people. Of course, BIOS programmers can screw up just as easily as windows programmers, and the ones at ASUS frequently do.

To the OP: CPU-Z should report an accurate voltage. The only time you shouldn't trust it is if it is reporting something strange. Generally it will read slightly lower than your BIOS setting, because boards vdroop (vdroop isn't strictly speaking bad, it's designed in for a reason, but it can get in the way while overclocking). On my board, it reads .03-.04 lower at idle and .05-.06 lower at load, but the DS3L is a known Droop Monster.

On that ASUS board I'd trust CPUZ. And definitely read up on your processor's recommended voltage range. Intel's tech specs should be required reading for overclockers.

It doesn't solve the issue with P5N32-E SLI's

I wish it did, unfortunately it doesn't.

Honestly, i have tried most programs and all of them report the same voltages, yet none of them report the correct voltage.

I just go by the BIOS now, and it hasn't hurt my CPU so far.
... have you tried the newest BIOS from Asus yet for your mobo?
post #33 of 43
Alright the BIOS has nothing to do with it.

I own this board and CPUZ Actually dosent read ure Vcore . It reads ure CPU VTT.

It only occurs with the P5N32-E SLI.

So use another program to read ure Vcore.

Hw Monitor is great and works perfectly for this board.

here is the link.

It seems it is an issue with the particular mobo then...this is why we had so many disagreements As a general rule CPU-Z is accurate though with regards to the particular mobo it seems like it is not. I hope this sort of sums up the discussion we had here.

it is a very interesting fact that people with VID 1.250v has 3.6Ghz at 1.38 for example..... and people with VID 1.325v has 3.4ghz at 1.44v..... and alll we know that we can esily push at 1.4.-1.45 at air cooling....... but over 1.45 is to serious.
So if there any posible limits in overvoltaging for low VID ( 1.20 ; 1.25 )
What do you think , people ?
Maybe the high VID is much stronger for overvoltaging ? and they will not start to mirgate the core/
So , what do you think ?

that "CPU-Z stuff" is definitely not rubbish. Comparing it with a program like HWmonitor will show you your voltage after vdroop and when under loads/at idle... etc.... in fact... in most cases, you adjust your bios and then check in cpu-z to see what voltage your cpu.

1.3625 on your bios could be 1.31 on one board... or 1.34 on another...

Its always useful to double check ur voltages once your in windows..

i put in BIOS 1.48125v for my Q6600 G0\\ VID-1.325v
and than check after applying and i see 1.444v
And thean go to CPU-z and see 1.44 in edle , and 1.42 in load....
1.42v in load is because Intel CPU's low down some viltage under load.
any questions ?

Which one is the one to go with ?

Use CoreTemp to read your VID.

CPU-z will tell you what your current Vcore is (in Windows at the time. So if you load up P95 for example the Vcore will drop as there is load being put on the cpu)

2 different programs for 2 different types of voltages.

For overclocking we set the vcore in the bios and see if its stable by stress testing. You cant really analyze the vcore accurately in windows. Cpu-z gives an approximate vcore (not always exact cos of vdroop etc.) and should be used as a reference. if you increase the vcore in the bios by 1-2 notches u may or may not see a bump in vcore in cpu. But if u increase it by 3-4 notches u shud see an increase in cpu-z plus a rise in idle temps.

IMO- Coretemp misreads the vcore depending on the BIOS and mobo you are using...for some mobo's like DFI...they adjust vcore by adding to the original VID, instead of just setting said voltage. In other words...as you scale vcore, the VID as CoreTemp reads it, will fluctuate or increase as well...
