Hello,
My b450 k4 have a memory problem. I install two a kit (8G*2) memory but not working in dual channel, it appears only single mode.
Check in win10 OS also say single, why?
If I need to return the board or the memory? Thank you for the help.

Dear Atheist,

Greetings, this is ASRock TSD.

Regarding this question, we provide some suggestions for verifying:

1. To activate dual channel mode, it is required to install identical memory (the same brand, speed, size and chip-type) DDR4 DIMM pairs to A1/B1 or A2/B2 slot.

2. To make sure DRAM slots are all functioning, please install one memory to each DRAM slot by turns to verify.

3. Please re-install the CPU.

4. If possible, please change another CPU to verify since memory controller is built-in CPU.

5. If possible, please change another memory.

Thanks!

All the best,
ASRock TSD
