[AlexandruGabriel123]

Hi,I have a problem with my memory,I have 8gb DDR4,but in task manager / ABOUT shows "8.00GB (6.63 usable)" how to solve this problem? A lot of games with "8gb requirements" don't work..
My specs :
AMD Ryzen 5 2400G with Radeon Vega graphics 3.60ghz
8gb DDR4
NVIDIA GeForce GTX 1050TI
1TB.
Sorry for the inconvenience, I do not know very well in this area. (Translated with GOOGLE)

Your CPU will reserve some RAM for onboard graphics - may have to disable the onboard in bios.
