Hi!

I had a small problem my gigabyte motherboard by default drops my CPU voltage when i'm running intel burn test. For example in bios i manually set my CPU core voltage to 1.35V but when i'm running stress test on desktop my CPU core voltage drops to 1.21V way is that ? Temps are ok.

Which feature in bios i had to change to resolve this issue ?

Is it becoming unstable?

Please Fill out your System Specs Page in your profile to include your cpu cooler too.

First while current technology makes them pretty close you shouldn’t rely on software sensors. If your not crashing I would leave it at that.

Second this isn’t actually mysterious and almost all electronic devices do it. The option you are looking for in bios is called (most likely) vdroop and will help stabilize the drop.

Try

1 - updating Bios if motherboard is new
2 - check for any power saver in bios if enabled or disabled
3 - reseting the bios
4 - Load line calibration ( vdroop )

Do as what these 2 have said to do. As what @Solaris17 and I said, if it is not bsoding or freezing you are ok. Electronic are not perfect and at times it will pull less or more power within ATX 2.2-2.32 tolerance specifications.

On my rig the board boosts power on its own to 1.524 from 1.476 under Max Load.

From 1.476 to 1.524 that's ok but a big drop from 1.35V to 1.21V and the system it's stable for me that means that the CPU doesn't need all that voltage and at this point i would decrease it and run the CPU at 1.22V with maybe a boost under max load to 1.248V./1.26V
