Hello everyone,
today I finally decided to do something about my RAM in notebook because I really don't know what is going on with it.
I have an old notebook Acer Aspire 7754G with 6GB of RAM (It is written on the case and there are 3 slots used when I peak inside)
I reinstalled the notebook several times and it doesn't matter what Windows I am running, currently I have clean installed Windows 10 and in System tab it only shows 4GB RAM (Screen included)
I alsou found out on the internet that the graphic card could take RAM for it self but CPU-Z shows that it has only 1GB (On the case is "up to 3806 MB HyperMemory" - don't know what it mean)
It also shows that all 3 slots are used
I will provide you with all screenshots.
If you can tell me what is going on and where are the 2GB of RAM it would be awesome
Thank you

My guess is broken memory slot or well... it's just loose.

Are your SODIMM's the correct voltage?

I didn't change anything in bios other than boot priority.

I get this notebook from my cousin and there was already this problem. 

CPU-Z shows 1.50 V in every slot and it is weird because it sees 6GB (on the 1st screenshot)

Where else should I look or what I should be looking for in bios?

I would check with the manufacturer. Some BIOS limit themselves to a certain amount of RAM.
