Need assistance with upgrading your RAM.
You're upgrading your RAM, which is great! Just check if both the current and new RAM are compatible. Your old specs are DDR4 8GB at 2400mHz, and the new one is DDR4 8GB at 2666mHz. Make sure the speed and compatibility match—generally, they should work together, but it's always good to confirm with the manufacturer or a quick test.
It's recommended to use a compatible configuration. Mixing RAM isn't reliable due to varying specifications. Both components can operate at 2400 MHz if they match. Your calculations seem incorrect—actual timing is 14.1/14.2 ns, not 7. Make sure you're using the effective frequency instead of the nominal one (1200 MHz).
Order a 16GB 3200 or 3600 MHz RAM module and finish there, skip the rest because they're too expensive. If you really need top speeds, get a crucial ballistix and build it yourself. If you can't find one, just hope for a Hyundai CRS/DJR or buy a Corsair kit and end up with something terrible.
There is a high probability of success. There are times where if you're using an OEM system (think Dell or HP) that you can run into issues if the RAM you're using requires a higher voltage than the JEDEC standard (1.2V). You're unlikely to run into an issue here though.
