   Good day

On B650 ProRs some confusion with DDR timings settings. When set up a value on AMD Overclocking tab and rebooting i noticed that in Windows there is nothing changed and system loads the last EXPO profile settings, but however BIOS shows the last entered timing value. What can be the cause of this confusion?
Also with using RAM ARGB, it works well with Asrock MB ARGB utility, but there is necessary to launch this utility every time when i want to shut the LED down. I do not find some options in BIOS; it woud be fine to able set the DDR LED state off under BIOS

	Hi Alex, what are you using to verify the timings in Windows? If you are using CPUZ then you need to check under the "memory" tab for the current "in use" timings. If your Windows listed timings are correct then it could be a case of your system tried to apply the custom timings, failed then silently reverted to stock timings to continue POST. You can test this by applying looser (higher) timings in the BIOS and seeing if those apply. The system should have no issue training on looser timings than default so this will tell you if the settings applied in the BIOS are actually active in OS. As for RGB/ARGB, the only settings I am aware of are under "Tools" -> "RGB LED" in your BIOS, have you tried setting "RGB LED Mode" to off?
