========================
Detailed description：My laptop (Asus Vivobook X509UA-BR236T/Core i3-7020U/4G/512GB SSD/15.6HD) already have 4 GB DDR4 2666 RAM soldered, product by Micron. I want to upgrade for another 4 GB DDR4 RAM. At ASUS website product specification said that they supported 2400 MHz DDR4 RAM. So should I try with 4 GB 2400 RAM or 4GB 2666 RAM? And will both of them work and run with dual channel? Thanks a lot!

Hello DPR Live,
This model support DDR4 2400MHz.
If you want to work with dual channel, 2 RAM need to be in same spec and size.
Thank you.

Thank you for your answer. But just to make sure, will this model compatible with 2666 RAM?

Hello DPR Live,
You can install 2666, but it may not run 2666.
Thank you.
