Could you verify if it's an X8 or X16 RAM? The video helped me understand how it affects performance.

I bought an 8GB DDR4 RAM for my laptop just to confirm its speed—specifically looking for X8 or X16. The serial number I found is CT8G4SFRA32A. I also checked the RAM physically; there were four chips visible on the front, but nothing on the back. The AIDA64 and CPU screenshots are attached.
It refers to a specific configuration of RAM, likely indicating eight GB of memory.
I checked whether it was an x8 or x16, and confirmed x8 is about 20% faster than x16 according to Linux.
It's a single rank, consisting of 4 chips each with 16 bits = a 64-bit memory stick. This setup would offer less performance than using 8 chips at 8 bits each, either single or dual rank. The benefit of such a stick is reduced power usage... in practice you might gain a few extra minutes from your laptop battery.
In response to poor results, it might be wiser to lower the voltage instead. This approach is one-sided, but since it’s so bad, using fewer chips could help. I’ve noticed older models sometimes had multiple chips on one side—like 8 chips in a single 16GB configuration, not the usual 8 chips split across two rows. DDR4 was phased out, and such setups are rare these days. Overall, it’s a weak performance with only four chips instead of eight.
Please share your laptop's specifications and let me know what level of performance you're aiming for.
