PC with dual channel RAM gives BSOD, how is that possible?

Question

Iron

The computer completely refuses to work with RAM in two channels, constantly reboots after blue screens.
Bios sees two bars, left it running for several hours and there were no troubles. Memtest86 also runs without errors. But as soon as you start loading Windows, blue screens immediately pour in.
With RAM in one channel, the PC works fine, no matter which bar and which slot I combined them in different ways.
The image of windows 10 home 1909 from the official site, the drivers and bios of the latest version, all the hardware has been working for less than a month.
I looked at the memory dump (in fact, I don’t know how to analyze it), but there are such lines
DEFAULT_BUCKET_ID: WIN8_DRIVER_FAULT
PROCESS_NAME: TiWorker.exe
CURRENT_IRQL: 2
PC Components:
Motherboard Asus Prime A320M-K
Processor AMD Ryzen 3 1200 3.1GHz/8MB
Asus PCI-Ex Radeon RX550 AREZ Phoenix 2GB GDDR5 (128bit)
Chieftec Value APB-500B8 500W Bulk
AMD DDR4-2133 4096MB RAM

Answer 1

A temporary solution to the problem is to lower the frequency of RAM in the BIOS, in my case from 2133 to 1600. Thanks to this, the PC has been working for almost two days without reboots and blue screens with memory in two channels.
The normal solution to the problem is described below Dance Macabre , plus ASUS support recommends the same.

Answer 3

It often helps to swap memory strips or stick them not into different channels, but into one channel, starting from the slowest to the fastest. Often the BIOS shows at what frequency the memory is running, and at what frequency the computer will work with it (and whether it will) - it entirely depends on the memory controller and the BIOS.
