Core Voltages and Load Line Calibration

Neil79 · 11 Nov 2011 at 22:20

I'm having trouble setting the right Volts and Load line levels, If i set a voltage of 1.350V and a level of 5 in bios it shows up as 1.40V!. In windows 7 using any voltage results for example easy tuner 6 it shows 1.368V.

What would I set for 1.38V for example?

Im testing 4.7GHZ/4.8GHZ

I set 1.370 Volts with load line calibration OFF and it shows 1.41v in bios! which is too high so i turned it back to my original setting 1.350v Load Line level 5.

Seems i'm unable to get 1.38V and stay near that it's either too high in bios or vdroops to 1.36

Nope

EDIT

Why don't you use dynamic vcore (DVID) also known as the Offset Voltage? I'm using it for my overclock 4.0GHz @ 1.260v. No vdroop and It's rock stable.

Ahh so DVID = Offset, What should i set that too?

It says

" DVID/OFFSET is ONLY adjustable If Vcore is set to Normal "

Thanks for the help though

DVID = Gigabyte Dynamic Vcore. Vcore must be set to normal or DVID will not function. All C states and EIST etc must be enabled.

The idea is to 'find' the max Vcore necessary for stablity. Then 'know' what is the normal cpu voltage supplied by the board's bios. Not something you set but Vcore supplied automatically by board bios.

Then subtract default Vcore from the Max Vcore needed for stability. This resultant number is inserted as the DVID setting.

Thus DVID is NOT some arbitrary 0.1 or 0.4 setting but an actual value determined setting by testing and doing the math.

Thanks man, sure i'll get this sorted somehow lol

Which is better to use LLC or OFFSET?

Neil79 · 12 Nov 2011 at 14:45

How would i find my lowest stable manual voltage?, do I boot up at default settings on auto volts?

Or should I just try +0.020v

Right avoiding the offset mode for a sec

With load line at level 6, 1.350v My volts during intel burn test are going up to 1.4v and dropping to 1.380v

Thanks man, wish me luck lol

ooops

0.0020v+ Load Line level 5, instant BSOD
0.0070v+ was giving me 1.205V in Bios, so i booted it up but at 3.3GHZ default speeds

It said " idle voltage 0.881V " and Load voltage in Intel Burn test " 1.181V " Instant System Shut off

Think i'll stick with LL

Thanks anyway, some help is better than none at all

Crashes EVERY single time with Offset mode, even had it set to 1.356v as soon as I loaded prime instant BSOD. Yet 1.345V/LL Level 5 and it doesn't

Yeh I looked at that but look at his load line ( LEVEL 10 )

I needed 1.38v Vcore with Level 10 Load-Line

His actual load voltages are 1.476, at that voltage he is on the edge of a dead cpu. Level 10 load lines are extreme on this board.
