Explanation

When mixing RAM modules with different speeds, the system defaults to the speed of the slowest module to ensure stability and compatibility. The installed modules run at 1,066 MHz and 1,333 MHz. To maximize reliability, the system bus will operate all modules at 1,066 MHz (the lowest common speed). Running mixed RAM at the higher speed risks instability or POST failure. Note: 8,500 and 10,600 are the PC3 bandwidth ratings (MB/s), not clock speeds.
