 ## System requirements
 
 * 2 GHz dual core Intel/AMD 64-bit processor
-* 4 GiB RAM (system memory for physical and virtualized installs)
+* 8 GiB RAM (system memory for physical and virtualized installs)
 * VGA capable of 1024x768 screen resolution
 * Network connection
 * 15 GiB of storage
 * Either a CD/DVD drive or a USB port for booting the installer media
 
-In the future, there may also be builds for other processor architectures. We would like to bring down the RAM requirement considerably.
+**Note**: While the system may boot with less RAM, 8 GiB is recommended for reliable installation and operation. Systems with 4 GiB or less may experience issues during installation due to video buffer usage and installer memory requirements.
