BIOS voltage and vdrop

I know this is a noob question... but just got my first Intel system up and running. I've been toying around with my 2500k, and I've been testing it at 4.5GHz, 1.335v.

Whenever I run LinX the voltage reported in CPUz goes to 1.302v. Which voltage is the correct one? I haven't compensated for it with LLC, I just want to know if during the loading process the voltage is 1.335v or 1.302v. Thanks.

Use another program (like Gigabyte's EasyTune6) to check your actual Vcore volts... on my system, CPUz erroneously reports VTT as 'core voltage.' I don't recommend using ET6 for anything else besides the voltage monitor... don't use it to OC your system.

Your vcore dropping under loads such as LinX is normal. If it's stable then don't worry about how low it goes under load. The lower the bettery anyways!

Is your vcore hard locked to 1.335v's in bios or does it throttle down at idle? Your chip does idle at 1.6ghz with low vcore?

Thanks for the suggestion Charlie98, will go about and find a copy. Off topic, but I'm in Plano :D

I know it's normal, I'm just confused as to which one is the accurate one. I assume it's the one with vdrop. And yeah, it undervolts to something like 0.96v at 1.6GHz

Your mobo is supplying 1.335v but because of the current drawn by your chip under intensive tasks like IBT the actual voltage is "drooping" to 1.302. As long as it is staying stable this is fine but you have the option of dropping the voltage a little and adding a little LLC to compensate. I have seen arguement for and against LLC so I will leave it up to you to decide.

AH! So we are the Chosen Few who have a MicroCenter close... :D

Yes, mine idles at 16x and about .940 vCore.

You can download ET6 from the Gigabyte website; you probably already have Smart6, I think I uninstalled that, though.

Here is a normal testing setup I use... LinX, RealTemp, CPUz and ET6 on HWMonitor... Note that CPUz is reading core voltage as 1.056v, which, as seen in ET6, is actually VTT.

Hehe yeah, that place is the only reason I moved from AM2+ to the Intel camp. I might end up having to go back there to swap this board, damn boot loops... D:

Anyway, thanks for that screenshot, much appreciated. I did uninstall Smart6, lol. I'll get to installing ET6 once I check the board for bent pins (long story).

Iono, LinX has never failed me... both should be respectable.

NEver tried Iono but wasnt to impressed with LinX, seems to be more intel optimized.
OCCT never let me down, its certainly better then prime and catches errors prime wouldnt.
