Are Asus z170-A motherboards faulty or is it just bad luck?

[Luis_65]

I bought a Z170-A motherboard since December, it results that my board was unable to boot if you connected a RAM stick in one of the last to slots; I called Asus support and they were nice about it, after 3 weeks they sent a new one for free, but now I have another problem with it, if I connect the 4 RAM sticks the system runs unstable and causes the blue screen of death in windows; I thought that may be my RAM was faulty I manage to get a kit of 4 sticks but the same happens.
besides that problem for some reason the audio card isn't working, contacted windows for support, the guys from windows took control of my pc to install the drivers, they had to force the installation from the safe mode but it didn't work.

so, this is why I'm asking you guys if you know something about this mobo, are all having errors or is it just coincidence?

(To use the PC I have to use only 2 RAM sticks if I use 3 or 4 the computer crashes all time)

Just to let you know I'm using:
Asus z170-A
intel i5-6600k
Kingston Hyperx predator 2400 MHz 4*4
Nvidia gtx 970 strix from Asus

Did all the DRAM come in a single package? Do you have the latest BIOS and mobo drivers? What CPU cooler? What's the actual model number of the Predators?

Yes it was a single package, I do have the latest BIOS I think it's 1702, my cooler is a corsair H60
the predators: HX424C12PB2K4/16

Look in the BIOS for believe it's DDRVTT (May be CPUVTT) and raise the voltage + 0.07

I tried but I couldn't find that option

Try CPU VCCIO, if not I'll pull up a manual and check

I already did it with the CPU VCCIO, it did't work, but I talked yesterday with Asus support, they said they will talk with the guy in charge of motherboards, but he won't be available until tuesday

Support center couldn't fix it, they said I should send it, so they can see the exact problem.

Did you send it? Did they see what is the exact problem? Any resolution?
