Minecraft Forums

so the other day, I was able to play Minecraft fine (running it off of the 2gb of ram). later that same day, I got back on Minecraft, but it gave me the error:

Initializing game

java.lang.OutOfMemoryError: Java heap space

I tried running Minecraft off of 8gb of ram, I was able to run Minecraft. However the next time I tried opening Minecraft it gave me the same error. So I increased the jvm argument to run Minecraft off of 16gb of ram. that was working for a couple of days before Minecraft gave me this error:

Initializing game

java.lang.OutOfMemoryError: Requested array size exceeds VM limit

what I noticed, (I used task manager to find out), is each time I opened Minecraft it would be using more ram than the last time. I have completely reinstalled Minecraft, deleted all files, everything. Idk what to do, I only have 16gb of ram so pls help.

Reinstall MC http://hopper.minecraft.net/help/guides/reinstalling-minecraft/

if you only have 16G of ram in computer why are you allocating ALL of it to minecraft, at most you should only allocate 8 to allow the computer to have some for other things running, like windows itself.
Being you are running vanilla 1G should be plenty

Yeh i would have thought so too, but when minecraft started acting up i tried increasing it as there was nothing else i could do
