AVX Problem (Bug?) on X299
I hope this is the right area for my problem.
I recently bought a new ASUS Rampage VI Extreme Encore with an i7 7820X
I managed to overclock this booi to around 5,2GHz, which is quite nice.
But unfortunately my CPU clock speed is rising up and down with no structure.
This bothers me hard. But i managed to find out, that the problem is AVX.
Everytime, when I open an AVX application my clockspeeds start to freak out.
It drops down to 3,3GHz and half a second later back to 5,2 or only 4,7 and so on.
The system becomes very unstable, and also unuseable.
I really dont have a clue why this is happening. I tried all Bios Versions which are available at ASUS
I also deactiavted everything with temperature and power.
Tried it with LN2 mode.
Nothing is changing this behavior.
The AVX Target speed is equal to the normal clock speed in Bios (Offset = 0).
Even if I try to put in 3 as offset, it doesnt respond to it. It just peak and freaks CPU clocks again down to 3,3GHz.
I tested it with Prime. If i activate AVX in Prime the clocks drop. Without AVX in Prime it is holding its clocks without any Problem (like any other benchmark too).
I really dont know what to do. And I hope one of You guys knows what to do. I would be very thankfull about it.
