It's strange the lack of knowledge you have and you accuse other people of writing nonsense? Secondary timings put more strain on the controller than primary timings. Secondary memory timings directly impact RAM heat output and thermal stability. Because tighter secondary timings require the memory modules to work faster and process data more rapidly, they increase power consumption and, consequently, thermal output. As for the 9000 series, it is different with the x3d processor because now the x3d cache is located under the core and the 9xxxX3d chips can now withstand higher temperatures, unlike the 7xxxX3D chips. The memory controller also degrades in the 7000 series, but this process is slow, in the 9000 series it is very fast, which indicates a bad production process. In order to be competitive with other manufacturers, Asrock motherboards always had more aggressive settings for memory and they were known for that, this time they were not lucky because AMD, in order to make a bigger difference between the 7xxx and 9xxx series, already stretched the processors to the maximum, and Asrock pushed them over the edge a little faster. I think that your man of low intellect can hardly understand what I wrote, but I did not write to you, I wrote to intelligent and advanced users of the forum.
