[SOLVED] 32GB of ram but motherboard only uses 16GB

[Stevetry]

Well i decided to add 2 more sticks of ram to make 32gb of ram for my PC i had 16GB but for some reason my PC or motherboard while detecting all 4 it still only gives me 16gb of physical memory

i tested the sticks by themselves and they work fine i also updated the BIO but nothing

The odd thing is windows knows i have 32gb but it won't use them it shows this

Looks like 32gb is being used,
You can check in task manager - memory tab - composition bar.

Also you should go into your bios and enable XMP

Im sorry it may say that but when i go to BIO is only says i have 16gb of ram and in task manager, while it says 32gb the pc can only use 16GB
XMP does not work

Well hi there again i fix the issue myself
It seems that unplugging the pc and clearing the Cmos and adding the ram sticks fix it and now the motherboard is giving me the 32gb.
