Cannot allocate more than 1.5 gb of memory despite having 16 GB of RAM.

Launcher Version: 1.0.1.3

Operating System: Windows 7, 64 bit

Java Version: Java 32 bit

Antivirus Program: About 3-5 seconds after I load up the world, the game lags, runs out of memory, then crashes. I tried to allocate more memory since I have plenty to spare, but the launcher only allows me to use 1.5 gb of Ram maximum.

Also, it has been working for about a week before then. After about 20 minutes the game would start to lag, but the game doesn't crash or run out of memory. I restarted the launcher just today and it gets the problem I said above.

This happened to me as well, only I have 4 gigs of RAM, 3 available for Minecraft. I think this has something to do with an update of some sort, that allows the Launcher to detect how much RAM is available. In other words, the Launcher might be thinking you have less RAM than you actually do.

I suggest using the x64 version of Java and seeing if that resolves your problem.

I am on the 64x version, but I just found a fix for the bug: If you're on a windows computer, put this into notepad

@ECHO OFF

"C:\Program Files\Java\jre7\bin\javaw.exe" -Xmx2048M -Xms512M -jar "C:\Users\<your username>\AppData\Roaming\.techniclauncher\technic-launcher.jar"

pause

If you're on Java 6, replace "jre7" with "jre6"

Replace <your username> with the name of the user you are using on your computer to play Technic pack with.

Save as Run.bat with the file type set to "All Files"

Double click the batch file to run it, and the technic launcher will pop up. You should then be set the RAM using Technic launcher, regardless of the fact the code says 2048 mbs.
