RAM Speeds
Hello, Your current ATX motherboard only supports 2133MHz RAM. You're planning to upgrade to 16GB of 3000MHz RAM and are considering a used mini-ITX motherboard that fits this speed. I heard some rumors about Intel i7-6700 handling 3000MHz RAM, but I'm curious if that's accurate. Is there really a significant difference between 2133MHz and 3000MHz RAM? Thanks.
It seems the i7 6700 works with DDR4 at up to 2133MHz. In practice, speed changes don’t usually cause big issues, though I don’t switch back and forth much. Upgrading to 3000MHz RAM could be smart for future compatibility if you plan to upgrade later. Running RAM slower than the clock speed isn’t typically a problem.
What kind of motherboard are you running? The 2133MHz setting is the typical baseline, while most boards support 2400-2666MHz for OC'd memory. Even with a 3000MHz RAM stick, it will only operate at 2133MHz unless you activate XMP/DOCP or tweak the voltage manually.
Yes, you can combine various RAM speeds depending on your system requirements and compatibility.
Yes, but this will limit your RAM performance to its lowest capabilities, making it only advisable if alternatives aren't available.
