How to buy RAM
Your laptop originally had 8GB RAM. The module lists 2666V, while the CPU shows 2667MHz in Task Manager. It seems the CPU frequency is higher than what your RAM supports. The Ryzen 5 3550H only handles up to 2400MHz. When adding another module, you should consider matching the frequency range or choosing a compatible one. You might need to purchase a module with similar specifications—either 2400MHz or 2667MHz—but ideally close to the current setting. The latency values differ, so ensure they align for optimal performance. For storage, you can opt for 16GB total, but it's best to keep both modules' capacities similar if possible. Let me know if you need further clarification.
The RAM performance is constrained by the CPU, so purchasing speeds above 2400MHz is irrelevant. Essentially, it doesn’t matter much. You can combine different brands and sizes, as well. Avoid extremely unusual capacities such as 24GB; it’s improbable you’d use that in a laptop with a CPU like the 3550H. 16GB works well as a standard amount—consider adding another 8GB if possible, aiming for similar speeds—but the brand isn’t crucial. A good choice is 2666MHz paired with an 8GB stick.
