Your MSI GL62M-7REX is running at a lower frequency than expected after upgrading. The new Kingston RAM you installed matches the specifications listed in CPU-Z, but the Task Manager still shows 2133 MHz instead of the advertised 2400 MHz. This could be due to dual-channel settings or motherboard limitations. Check your motherboard manual to confirm if it supports 2400 MHz in dual-channel mode. If not, consider returning the new RAM to avoid potential performance issues.
Ensure the XMP profile is activated within the UEFI/BIOS settings. The JEDEC timing table numbers shown in your screenshots represent the available supported profiles. These are the different configurations you can use. Note: Observing two distinct DIMMs could pose a problem, though it's unclear at this point.
The motherboard and CPU are compatible with DDR4 2400 MT/s. It seems Samsung and Kingston memory models differ in CAS latency, which may cause the board to revert to 2133 for smooth operation. Review your BIOS settings for manual memory speed adjustments; you might be able to enable 2400 MT/s without issues (especially at the higher Samsung DIMM latency). If not available, simply set it to 2133 MT/s—changes are unlikely to be noticeable. Consider swapping Kingston memory for a different model that supports CAS 17/18. This isn’t an issue; CPU-Z confirms both DIMMs use JEDEC 1200 MHz profiles.
