Hello,

I'm using 2x 4GB Kingston khx1600c9d3p1k2/8g on a Asrock FX990 Extreme4 with a FX 8350 and no matter wherever I put those sticks in, its alway single channel. Ive tried every possible combination (1+3 (blue); 2+4 (white); 1+2, 3+4, 2+3) and it always shows me that its running single channel. The 8GB in total are always detected, so the slots work for sure.
Bios is up to date.

Please help me.

Thanks in advance!
