CPU-Z is BS

It reports my Volts as 1.24 when it's set to 1.33 in bios. It reports it as 1.3 when I'm not running prime95 tho:confused: I'm trying to get to 3.6 Ghz
 
Hey Nate,

I just read your other RealTemp is BS :D

I think you need to do some more homework and make half an effort to understand something before calling BS :o

The voltage you set in BIOS and the voltage you get in Windows (Idle/Load) will nearly always be different. If you have a vCore figure in mind then use the readout displayed in the BIOS health menu page i.e keep boosting the voltage manually until the vCore figure under BIOS health menu matches the figure you wanted . . . . So if you want/need 1.400v doesn't matter if you set 1.600v if thats what it takes to achieve a 1.400vCore readout under BIOS health Menu.

The vCore you see under CPU-z should match the figure from BIOS (Assuming EIST is disabled). This voltage will either go up or down when the processor is under load (or maybe stay the same), this would depend how your system is configured with EIST, LLC, etc :p
 
Ah I see. So bios is always different then in Windows. So if I set it to 1.4 in bios and it shows as 1.3 in windows then I'm safe? I don't wanna go higher then 1.3. It's at 1.312 now idle. Now 1.264 after opening prime95
 
If you look in your BIOS there are two references to vCore, the first you know and that's the manual vCore control where you set a figure, the second reference to vCore is under the Health-Options page (where you can also see CPU temps etc).

Knowing this you can get almost the exact vCore figure you intend.

The difference between the figure you set and the figure you get is know as vDrop and its a very normal part of computing, everyone who understands the basics knows to almost ignore the figure they set and instead pay attention to the actual resulting figure.

The difference between the vCore when idle and when at load is known as vDroop and it happens under certain conditions. Most ASUS motherboards have an advanced BIOS option called Load Line Callibration which negates vDroop.

On my systems (with EIST disabled for overclocking tests) the voltage will either stay the same regardless of idle/load state, if it does fluctuate it will rise while under load (which kinda makes sense).

If you need more help or make new threads can you avoid calling something BS because you don't understand it! :cool:

Aaah thanks Big.Wayne I think I got ya now. I wasn't serious about the BS tho :p I'm doing some more homework now here http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3184&p=5 They say it's to do with the 45nm not the motherboard. I'm gonna just do 3.4Ghz for now it seems easyier.
Click to expand...

It's motherboard that makes the big difference. I used to have an ABIT IP35pro which dropped 0.1v between bios and cpu under load.

My current mobo is more like 0.02v or less.
 
Hope it's not BS, as when I O/C my QX9650, i have set Volts to 1.46 in bios, to get <1.31> in CPUZ (Speedfan/HW monitor etc also give similar readings of 1.31 - but the ASUS bios softeware in windows gives it 1.46 - like in the bios).

ASUS Striker II Formula
QX9650 (O/C to 3.5-4.0 depending)
 
Stop posting stupid attention seeking threads everywhere when you don't understand how software works.
