Guys,

I'm having serious problems with this board and I need some help.
I bought the board last week, along with a 2600k.

Since I installed it on wednesday, my board is acting weird (it's the least I can say).

The major problem is that it won't hold the VCore.
The board came with bios F3. After installing everything normally, I checked voltages in both bios and windows (using HWINFO, CPU-Z and ET6).

My cpu has these VID's at specific speeds :
3400Mhz : 1.225V
3500Mhz : 1.245V
3600Mhz : 1.275V
3700Mhz : 1.300V
3800Mhz : 1.325V
3900Mhz : 1.335V
4000Mhz : 1.340V
4100Mhz : 1.340V
4200Mhz : 1.340V
4300Mhz : 1.345V
4400Mhz : 1.355V
4500Mhz : 1.360V
4600Mhz : 1.360V

Now here's the problem.
After the first start, the bios reads the default VCore at 1.212V, which seems normal.
After booting into windows, VCore drops at various voltages, I've had 0.972V or 1.140V etc.... (this is to make a long story short).
Now, after a restart, the bios reads the same VCore as in windows, which seems kinda weird to me.
So, after, f.e., ET6 or CPU-Z read 0.972V, the bios, after a reboot, would give the same readings.

I went from bios F3 to F6, then F7b, F7f, then back to F3, now on F2, but the problem won't go away.

Here's an example with pics and screenshots (taken yesterday):

After reboot, VCore in bios reads correctly 1.224V :



Other settings in bios :



Then I booted into windows, and VCore drops to 0.972V (idle and load)



As you can see, VCore doesn't change at all and stays at 0.972V.

After a reboot, you can see that the bios reads the same voltage as in Windows, 0.972V



Then, I set Vcore manually at 1.320V :



But as you can on the pic below, Vcore still stayed at 0.972V :



I'm getting very frustrated with this board and I'm wondering what's causing this problem.
I reinstalled the CPU this afternoon, cleared CMOS and others, but the problem won't go away.

I'm considering returning the board and have it checked, unless the problem might be resolved very soon.
My first board upgrade in 2 years (coming from S775) and now this crap happens to me.

Anybody out here who might help me out?
