I have an ASUS VivoBook 15 M509DA-EJ741T (Ryzen 3 3250U). It has a 4GB RAM soldered, with an option to upgrade upto 12GB. So, I am looking for an 8GB stick. But, I am not able to identify the RAM speed of the existing soldered one. On running the wmic memory chip speed command, CMD says, it's a 2667 MHz RAM. But, on checking the Task Manager and CPU-Z, they say it's a 2400MHz RAM. Now, I have shortlisted an 8GB Crucial 2666 MHz (https://www.amazon.in/Crucial-DDR4-Laptop-Memory-CT8G4SFRA266/dp/B08C56KXQJ). Will this work for my laptop or will I have to buy a 2400MHz RAM?
