Running at 2133MHz (non Advertised speed) ? ※Whenever you insert RAM that's advertised with faster-than-standard speeds(e.g. above 3000MHz), just head to the BIOS and enable XMP to ensure that RAM is actually running at those speeds. While it's simple, it's easy to miss–especially if you've never heard of XMP and don't know you need to perform this extra step. Otherwise, for reasons your system might boot at the standard speed of SPD. (2133MHz/2400MHz in normal case of DDR4 memory, shown as 1066.7MHz/1200MHz in CPU-Z ). How to enable XMP ? 1.Enter the UEFI/BIOS setting menu.2 Enable XMP and choose the profile.3. Save and restart your computer.
