Not utilizing dual channel in the AMD Ryzen 5700h (laptop)
Not utilizing dual channel in the AMD Ryzen 5700h (laptop)
Hi all, I'm looking for a new laptop with a lot of CPU cores. I found a Lenovo model featuring an Amd Ryzen 5700h (8C16T). The main concern is its limited RAM—only 8 GB at 3200 MHz, with 4 GB already soldered to the motherboard. That means I can only upgrade the available slot. Should I go ahead and install a 16 GB stick there, sacrificing dual-channel performance? I've heard Ryzen CPUs perform better in dual-channel mode, but does the extra memory make up for that loss?
The laptop is mainly used for physics simulations, using software like Matlab and COMSOL Multiphysics, and I need 3D visualization. It has solid onboard graphics for this CPU.
Thanks in advance.
It could enter flex mode, making the denser RAM act like dual channel until it surpasses the other RAM's capacity. For instance, with 4+8GB, it functions well under 8GB but shows a performance drop once it exceeds that. If you require more capacity, opt for 16GB; for better performance, choose 4GB only.

Welcome to the forums, newcomer! Could you analyze the model for the Lenovo laptop you're interested in? A link would be very useful for us in two ways. Based on my experience with laptops from this brand, adding an 8GB or 16GB RAM stick would increase total memory, though dual-channel performance is doubtful according to CPU-Z. Additionally, have you explored workstation-grade laptops as per your needs?
