Problems with ram

[TheBiGSTACH]

Hi Guys.

I have problem with allocating more than 2900MB ram. I change settings in launcher on 7GB but it's not work. Yes I have 64-bit java 8. 

Do you have any solution to this problem?

For starters, there would never be any reason to allocate 7G in the Launcher, and many compelling reasons not to do so. Allocating more RAM than is actually required typically results in the client performing more poorly than it would with the appropriate amount of RAM. The rule of thumb is 3G or half your physical RAM, whichever is smaller.

As for why you can't allocate more, it needs an unused chunk of RAM at least that size and will fail if it's not available. Other processes must be using your available physical RAM.
