It's generally fine to use just two of the four sticks in a set, especially with Ryzen processors. The issue you're experiencing—flickering or artifacts—might be related to compatibility rather than the number of sticks. Using only two sticks from a different configuration (like your HyperX setup) seems to work without problems. However, if you're concerned about long-term stability, sticking with a full kit is recommended to avoid potential compatibility issues.
The purpose of a "set" is simply to align batches and timings for compatibility, so it shouldn't matter.
