Hello. So I had my computer running 2x RAMs 4GB 1866 MHz from Kingston but this was problematic. Sometimes it couldn't pass through POST procedure and so after running computer there was only a black screen. I thought maybe one of RAM cards was broken so I dissambled one and voila. It turned out that sometimes it could run 2 RAMs, sometines not. I bought new 2x RAMs 4GB 1866 MHz by Kingston and noticed the same behaviour. It led me to searching through Internet. I read that this can be a problem either with CPU or with motherboard. Some post I found in Internet told me I should increase CPU/NB Voltage and DRAM Voltage in BIOS but it didn't help. Now computer sometimes boot on 1 RAM, sometimes on 2, never on 3 or 4. I wanted to ask if you maybe know what can I do in order to get working 4x 4GB 1866 MHz.
Motherboard: Asrock 970m Pro3
CPU: AMD-FX 6300
RAMs: Kingston 4GB 1866MHz 4x
My default DRAM Voltage is 1.585 when I set it to auto.
My default CPU/NB Voltage is 1.1 when I set it to auto.
