Combining 2400 MHz and 2666 MHz RAM is possible but requires careful setup.
Combining 2400 MHz and 2666 MHz RAM is possible but requires careful setup.
I noticed the RAM frequency was adjusted. If possible, set it to manual mode first, then configure it at 2400 MHz. Follow the instructions in AIDA64—it will display several number sequences if you open the help or hover your mouse over them. There are many other settings available in the menus and options. I’m not very familiar with the BIOS or those interfaces...
