hi

i bought my v3-772 V3-772G-54204G1TMAKK  NXM9VET002 in late 2013 with onboard 8gb of ram ( 2 x4 gb kingston pc3-12800 11-11-28-39 marked ACR16D3LS1NBG/4F).

A month ago i decided to upgrade to 16 gb with another 2 module of kingston pc3-12800 11-11-28-39 marked 99U5469-045.A00LF.


Now, the problem is windows see all 16 gigs of ram but use only 7,88 gigs and reserve 8 gb for hardware. Bios see right size and also cpu-z. I tried to upgrade to last version of bios, format the disk and reinstall Windows 10 but the problem still remain.


It's a bios fault? i don't have any option to remap memory and bios is very lack of option.


what can i do?


thanks
