Pixelmon Mod

i cant figure out how to increase the ram ive tried all java's I have (didn't work) the max It will allow is 2gb out of 16gb from comp. can someone guide me plz? im a derp so idk much..

Try going into settings in the launcher and change the variables in the java arguments to the desired memory. For example this is what I have

"-XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx1024m -XX:MaxPermSize=128m"

C:\Program Files (x86)\Java\jre7\bin\java.exe is the java it auto sets (wont let me change)
and wont let me go past -Xmx2048M -Xmx1024M aka 2gb I tried your thing and it sadly crashed the launcher xD (idk how that worked) but it sadly didn't work :/

Do you have ram to spare?

I'm having the same issue. On my regular launcher it works, on the pixelmon one it does not.

I have the same issue too. I have tried to increase the RAM allocation to 2 GB and it just wouldn't go. I have it pointed to the 64 bit java that's used in the new Minecraft launcher. I know I have more than enough ram to handle this.
