Random Freeze/Hang issues with Gigabyte Z170 Gaming 7

[nbuubu]

I've been experiencing bad and frequent random freezes in Windows, Memtest, and even while idle in the Bios.

Installed the Gigabyte Z170 Gaming 7 this week, along with an Intel Core i7 6700K and a pair of Corsair Vengeance LPX DDR4 ram sticks (CMK16GX4M2B3000C15R, listed as compatible on Gigabyte's website). From day one the system randomly freezes and hangs.

I've done fresh installs of Windows 8, and 10, and it still freezes. First thought is that it's the ram, and I tried running the system with ram in different slots and then individually, and the freezes still happen. All settings are at stock.

I've also installed the latest beta bios for the Gaming 7 released yesterday, and the issue persists.

Does anyone know what the problem could be? I bumped up the System Agent, VCCIO, and Dram Voltage, then turned on XMP ... resulted in an instant crash and blue screen at Windows. At stock voltage and speeds, never overclocked, I get full system freezes, not blue screens.

Any idea what this could be? I have new ram arriving on Monday but if it's not that, I suspect the problem is either the board or CPU. Any way to problem solve this? Because I get no error messages from Windows and the board itself is showing "AO" which means IDE initialization (?). I just took the entire system apart and put it back together and the problem persists. Running a Corsair AX850 with a single video card so I doubt the problem is power.

Any help would be appreciated.

Am building one next week so will let you know how it goes I am using the Z170ud5  though and some 3200 memory.

I have the same CPU, motherboard and Corsair 16GB CMD16GX4M4B3300C16 DDR4 memory on an Intel 750 Pcie SSD. The exact same issue. I have flashed the Mobo to the new beta 6f. Hopefully that does the trick. Did you solve your freezing issues?

I'm having the same issues. I'm running a ga-z170mx-gaming5, gskill ddr4 memory 3200 that is on gigabytes support list. I5 6600k no over clocking on anything. 660 ti video card. Windows 7 64x. My system loads fine. But it will hang up randomly. I don't even have to be doing anything. Kind of a noob to pc work. But quick on understanding and learning. I did get a blue screen. Looked up the dump file and it says something about the cpu and/or memory could be bad or the drivers.

I have same random freezes/hangs issues. Same motherboard - Gigabyte Z170 Gaming 7 / same ram CMK16GX4M2B3000C15R but i have i5 6600k. It randomly hangs - during movie playback using VLC... Browsing internet using Chrome with 3 to 6 opened tabs... And music playback using foobar 2000. To restart i have to hold the power button to turn it off because when i push restart it does not react (restart button works fine - i checked...)

Try setting slice ratio to 10.00 (In BIOS goto M.I.T., advanced frequency settings)

thx marchi3316 i will try it.
Right now i run my system on updated beta bios version F7o and random freezes gone. but when i try to turn on xmp profile it put artefacts on screen when i watch video and try to drag any window to the side... when xmp profile is off everything is ok.
