The XMP profile is activated with a negative impact on performance?
Hello, I just assembled my first PC with the Ryzen 5600X CPU and achieved a Cinebench R23 score of 11272 across cores. Later, I found my RAM was set to 2133 MHz. After turning on the XMP profile in BIOS, it adjusted the RAM speed to 3600 MHz, which matches their supported rate. However, the score dropped to 10836. Can someone explain why there was a performance decline?
If you tested the benchmark from a cold start and then ran it again after it stabilized, the results would naturally be lower.
Warm up the system for a few minutes before testing, so you avoid getting stuck with unrealistic scores.
The timing performance on that setup might suffer if the CAS Latency is high—like 19...—which could reduce the frequency advantages.
It also made the hardware more affordable, I'm sure.

It probably helped make the unit more affordable.
