Due to the limitation of Windows 7 32-bit operating systems, the maximum of usable memory size is less than 4GB natively.

To increase usable memory under Windows 7 32-bit OS on Intel Skylake based systems, please adjust [Top Of Lower Usable Dram] to [3.5GB] and then check the usable memory size again.
