Need Help, Custom Modpack Will not work.

[Igorthor]

Hi all,

 

I am new to Minecrafts' mod, my friend made a custom modpack. I was able to play up until I updated to Java 7u65, and uninstalling previous versions of JRE. I was then unable to play the custom modpack. I committed to a system restore, but to no avail, it still did not resolve my issue, it actually wouldn't let me install Minecraft nor Technic Launcher. After continuous searching, I removed all Java installations and re-downloaded/ re-installed JRE7u65(64 bit){ My OS is Win7 64}; I re-installed Minecraft and Technic Launcher(Confirmed it operation with a new SSP world, as well as Confirmed operation of Technic ; by loading Yogbox and starting a SSP world, aside from that, I tried to start a SSP of "Attack of the B Team" and it crashed). From there I came here searched and found a few similar issues:

I have read those and am not sure what I can do on my side or if the author should do something on their side. I have gotten the launcher to install and run, I have gotten the Custom Modpack to download. At this moment, though, I am not able to get the Modpack to properly execute to the minecraft menu. It gets to the Mojang screen, halts (non response), and crashes. I have in the past tried to install older versions of JRE. I have increased my Launcher RAM to 11GB all the way down to 512MB. I have created and since deleted a System Environmental Variable of " _JAVA_OPTIONS/ -Xmx512M". But nothing has worked thus far.

 

TL;DR: I have installed JRE7u65; reinstalled Minecraft and Technic Launcher( confirmed working); I have downoladed a friends custom modpack  and am getting a  "java.lang.OutOfMemoryError: Java heap space" with using upto 11GB of Ram Allocated. With the game freezing and crashing at the Mojang screen.

 

Please Help,

 

Here is the links to my crash report and the console log

You are getting an out of memory error (heap space). This is the memory line from your report:

Memory: 82191752 bytes (78 MB) / 493355008 bytes (470 MB) up to 493355008 bytes (470 MB)

This is your JVM flags line:

JVM Flags: 4 total; -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx512m -XX:MaxPermSize=128m -Xmx512M

You are quite clearly only allocating 512M to the launcher: -Xmx512m

Yes at that report I did allocate 512MB, as having previously tried every RAM allocation. I just re-ran the Modpack with 3GB allocated via the launcher.

 

Here is the updated Crash Report:

Updated JVM Flags line:

 

JVM Flags: 4 total; -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx3072m -XX:MaxPermSize=256m -Xmx512M

 

Not sure if this helps. 

 

Edit- I have seen plenty of your replies, I am glad you responded, thanks ahead for all the hard work you do to help us!

Hi,

 

Hey Plow, thanks for your help. I have figured out the conflict.

 

Through trial and error, I have Matched the two "-Xmx" digits and placed their values at 3072M.

 

With that I was able to menu the game using his modpack, and then ultimately connect to his server.

 

What I did was went to Microsoft Button>Right Click "Computer"> Properties> Advanced System Settings> Environmental Variables> System Variable "New"> Inputted "_JAVA_OPTION" and for Value " -Xmx3072M".

 

Thanks again, I hope this helps someone in the future.
