Fixed Voltage Readings Help!

post #1 of 11
Thread Starter 
Got my 3770k yesterday with my ASRock z77 oc formula, everything was overclocking wonderfully.
Reached 4.4Ghz @ 1.205V and temps below 65C.
As soon as i change to x45 so 4.5Ghz and test @ 1.205V
I load up windows open up CPU and Prime with Large FFT's and notice that my temps were extremely high around 87C
Looked at CPU-Z and noticed my Voltage are at 1.400V...
I have tried clearing cmos, changing the multiplier etc...
at 44x it goes to 1.205V but at 45 it will instantly change to 1.400V and disregard my FIXED Voltage.

HELP!

It's normal to read little higher voltage.
Example on my board when I fix 1.300V Windows read like 1.316V than when some LinX or Prime95 start, I mean 100% Load reading is more higher about 1.327V but nothing so high like you describe.
It's best way to ask on ASRock site technical support for your motherboard.

1.2v stable for 4.5 is very nice. you got a good cpu there. So to answer your question yes the voltages are right, if you can go even lower good for you but i would just leave it there cause it looks pretty stable

Did you guys even read my post?

Anyone who is actually taking there time to read this,
Even now at 44x it is doing a AUTO voltage
Voltages are not being communicated to windows.
1.4V @ 44x when in bios i have it set fixed mode at 1.205V

What level of LLC are you running? Maybe the board auto-defaults to a higher value at higher freqs or something. Have you tried setting an offset voltage instead?

I'm running LLC level 1 as there is about a 0.01V Droop not too bad.
I don't understand how offset works and after years of using fixed i don't want to learn it!
Anybody with a ASROCK Board Please!

Got the same mobo, running at 4.5 and have a fixed voltage set at 1.25V.

I dont see any of the issues you mention.

You running latest BIOS?

I think Level 1 is the highest level for ASRock boards. Try level 3 and see what happens. At high levels on LLC the boards will often end up adding voltage instead of just countering Vdroop.

As for offset, it is easy. Offset voltage adds a fixed amount (which you set in the BIOS) to whatever voltage the chip is requesting for that frequency. So if the chip is asking for 1.2V then a +0.05 offset will result in 1.25V. If the chip is asking for 0.90V (at idle) then the final voltage will be 0.95V. Auto voltage is basically just offset where the motherboard is choosing the value for the offset. To set it up you'll need to find your stable voltage for your overclock, using the manual voltage method, then switch to offset, put in an offset amount (you'll have to guess at first - something like +0.05 is a good start) and check and see what voltage that delivers. Then go back in the BIOS and adjust the offset to what you need to get back to the manual voltage you found earlier.

In theory you can use CoreTemp or RealTemp to find the Vid (what the chip is requesting) at the same time you are finding your manual voltage, and then use that to get your initial offset amount - but I don't know how accurate the CoreTemp/RealTemp Vid value really is.

that's your problem. the lower the LLC leve - the more volts you'll get - LLC levels adds more volts than offset-values or fixed - so yes, try lvl3

Ok, so i have updated to the most recent bios, the beta bios, L1.10a.

Hasn't made a difference just a few more settings,
even at LLC level 5 my voltage is incorrect!
LLC1, runs my CPU at 1.4V at level 5 its much better Voltage at 1.288V
But still how does it get from a fixed voltage of 1.205 to 1.288V?
This is really starting to annoy me and if this persists i am seriously considering returning this board, was reading a thread about ASRock "cheating the system" with there voltages and thought it was all baloney since that is what everyone was saying.
But now i see the truth to the post,
pathetic on ASRocks part if that is the reason why my voltage is spiking.
