Speed changes in the CPU core
Speed changes in the CPU core
Your CPU speed changes unpredictably between different frequencies, and you're experiencing performance drops after upgrading your motherboard. The RAM speed isn't matching what you expect because of these fluctuations. To stabilize things, try checking RAM compatibility with your BIOS settings and ensure your system is properly configured for the new hardware. Consider using a more stable CPU model or monitoring temperatures to prevent overheating issues.
DDR boosts performance so the actual frequency reaches 2133MHz, meeting the lowest DDR4 requirements. The XMP setting isn't applicable here. When a CPU core is idle, the clock slows down to conserve energy. You can turn off AMD Cool & Quiet to keep the processor running at full speed and voltage continuously.
