Minecraft Forums

ive been having crashes on minecraft lately with my memory/ram usage. i have a computer with 16gm ram. ive tried a couple things but nothing seems to increase my memory on minecraft. when i edit my profile on the MC launcher, check JVM arguments, and edit the "-Xmx1G" to anything more then 1G, and then run MC, the memory usage still stays the same. ive also deleted everything in the JVM and put in a code something like -xmx xxxxMB or something like that, and that didnt work either. can someone please run me through how to enable more ram on MC so it stops crashing?



thanks a bunch

i dont see anything in the last tab (profile editor) to copy. do you mean the tab "launcher log"?

before i launch game http://paste.ubuntu.com/8275500/

at title menu (with mods and texture packs) http://paste.ubuntu.com/8275528/

when i run minecraft right now i have used memory at 350mb of 499mb and allocated memory at 100% (499mb)

and when i change the "-Xmx1G" to 2G, or anything else, nothing changes.

You probably have a _JAVA_OPTIONS injecting a parameter of -Xmx512m this might come from environment variables, but some users are never able to find the source of it. Although in that case I think a few have eliminated it by uninstalling and re-installing Java.

Or like this guy, not able to figure it out how to remove it permanently: http://www.minecraftforum.net/forums/support/unmodified-minecraft-client/2176223-unable-to-allocate-more-ram

awesome, found the fix in that post. turns out java options was set to -xmx512m not letting anything go higher, went to Start -> Control Panel -> System -> Advanced System Settings-> Environment Variables and deleted the java option causing that. thanks for the help!
