Why?? Minecraft won't let me allocate more RAM in windows 10

[junzhi2002]

Just like the picture shown, my computer have about 3.7GB RAM free to use but it just simply don't let me use more than 1GB ram in minecraft.....

Can anyone help me to solve this problem?

How much RAM does Minecraft use? Does it ever use more than 1GB? Who said it needs more?

-Xms1024M -Xmx3072M

I generally gets lag when i play Minecraft and you can simply add more RAM to Minecraft in the profile section. It use 1GB but i tried to use 2GB then it crash me

the game will pull whatever RAM it needs if there is any available. unless there is something very specific you are doing you have no reason to allocate more ram to the game than it needs. 

 

tl;dr the game will use as much RAM as it needs. you have no reason to allocate any to it.

In Minecraft it's a special case, since it will restrict its ram usage by itself, if you done allocate more ram manually, it will lag after sometime.

do -Xms1024 -Xmx4096

 

are you shure it is the ram that is causing the stuttering?

im no expert. Games usually uses whatever ram they want to

I believe 32bit Minecraft/Java has a 1GB limit. Reinstall JRE 8 (64-bit) and Minecraft.

 

Edit: Never mind. OS is not 32 bit, but still check if its 32 bit programs
