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.

You need to test your RAM sticks...and your motherboard slots, as suggested in the following guide.

How do you have the modules populated?


The DIMM slots are labeled DDR3_A1, DDRC_A2, DDR3_B1, DDR3_B2.


The suggested population is seen below.



Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
