Dual channel not working

[africsnail]

Hello,
My RAM was long time not working in dual channel. I figured out that it was by the CPU cooler (CM 212 evo) by it's metal pieces connecting to the mb. Now it boots up, but after few minutes of gameplay or mining crypto whole pc freezes, no q code on the mb. Whenever I put my RAM back into B1, B2 it's working again. Thanks for your answers.

Is the B1 and B2 you are referring to the RAM slots? Your Ram sticks should be located in either A1 + B1 or A2 + B2.

It's working in B1, B2 only. In other combinations it's freezing after while. I know it should be A2 B2 and so...

These two RAM sticks were bought together as a matched pair?
