Just a reminder that I get exactly the same behavior on my board when setting the vcore to 1.205V (fixed).
From HWInfo I can also see the VRM output is jumping, as if it is in offset mode.
OH it happens to you too! Haha must be a bios thing then lol, its really weird tongue.gif

For those who use offset VCore, do you get constant fluctuations? When I had an Asrock Z68 Gen 3 Pro my VCore would stay at minimum at idle and increase as it needed it. I brought over pretty much the exact same 4.6 OC settings from that board to this board and I can sit and watch my VCore go up and down constantly from .8 to 1.33. Up and down, it never stops even at complete idle.

For offset I believe this is normal. Which seems nice, but you can do it better with fixed.

1. Set fixed voltage for your stable OC. Also LLC level 1.
2. Make sure Speedstep/EIST is on.
3. Enable all C-states, and for the 'last' setting I use 'C2'.

What I see is that the max voltage is never above the fixed voltage, but when idle, the CPU will request less voltage.

From HWInfo you can see all this in action, look at the CPU VID section and the power from the CPU and VRM.

I've noticed people sticking with fixed voltage for this motherboard, but with the Fatal1ty Gen3 Pro it seems we were always trying to find the best setup to keep voltage low at idle. Is fixed the preferred setting for this board? I'm currently running a 4.6 GHz setup with offset and LLC 4 with all C states enabled.

Check whether they are benchers or 24/7 users which would probably determine how one uses the Vcore settings.

Anyway, no issue for me using Offset Vcore for my 2500K and 2600K, each at 4.7GHz on beta 1.15G.

OK thanks. I'm gonna mess with offset, not really a bencher. I just upgraded to 1.40 last night. Haven't had a chance to test it yet.

Thank you! I will work on it tomorrow. I'm impressed so far, much more stable board than the Pro Gen 3 which wasn't too shabby to begin with.
