Recently I buyed the Asrock H77M motherboard. There is something what confuses and worrying me.
I suppose that most of you guys(girls) know what LLC (Load-Line Calibration) is.
The source from the quote below this line is this: http://www.overclock.net/t/1198504/c...asrock-edition
CPU Load-Line Calibration: Level 2 or Level 3 (whichever one will get you closest to BIOS Vcore)
~When a CPU increases to max speed, the Vcore usually tends to drop down. This is known as Vdroop.
If the Vcore drops down too much, it can lead to stability issues. To combat this, CPU LLC was made to offset this loss.
Level 5 (0%) will net you the least compensation, Level 3 (50%) an average compensation, and Level 1 (100%) the most compensation.
You want to find the setting that will get you the same Vcore that is says in BIOS, during load in Windows as reported by CPU-Z.
~Level 1 seems to spike your Vcore up really high during load, so I do not recommend using that.
As you can read the setting 100% (level 1) gives the most compensation. That means more voltage under load. On the other hand, 0% (level 5) gives you the least compensation.
But it appears that in my UEFI this settting mean different things.
When I reset the bios of my motherboard to the standard settings, the LLC is set on auto. However, the auto setting mean in my case 100%!
I can see that because the actual setting can be seen in the middle. Between the name of the setting and the setting you can manually set, even if it is set on auto. Photo below this line to illustrate:
Testing time! (With Intel Burn Test)
The CPU voltages at 100% and auto were both: 1.128V at load and 1.152V at idle. So the auto setting is set at 100%.
The CPU voltage at 50% were: 1.144V at load and 1.160 at idle.
The CPU voltage at 0% were: 1.168V at load and 1.176V at idle.
This is bizarre. As far as I can find, the 0% setting should give less voltage than the 100% setting. However in my case it is the opposite, the 0% gives me the most voltage.
What do you guys think? What does this mean?
It actually worries my because I read about voltage spikes damaging your CPU if you using LLC.
Is this a faulty bios/bug? Or is the explaining wrong at the Complete Overclocking Guide? Or Asrock changed it on purpose for some reason.
They were also too ¨lazy¨ to put a explanation in the description of this setting in the uefi, nothing in the manual either. And the most stupid thing is: I can´t disable it!
Is it possible that the bios suddenly becomes ¨unstable¨ or ¨decide¨ to do things right and changes the settings to the normal meanings??? So that 100% means suddenly means more voltage. If so, I have a problem.
What do you guys think about this??
