Hello There. First of all sorry about my english.

I have already lost a lot of time searching for a solution, but nothing I do works. I recently installed the 1.7.2 version of minecraft and wanted to use the 512x512 or 256x256 BDCraft texture pack. However, whenever I try to launch minecraft it crashes. And yes, I used MCPatcher. What I have tryied:

* Changed the parameters to -Xms4096M -Xmx4096M
* Tryied 4G
* Tryied with 1GB,2GB and even 8GB
* Reinstalled both JAVA and minecraft


I have Windows 7 64 Bit and Java 64bit. I also have the Java SE Development Kit 64bit that I used for android apps development back in the days. The error in the log is the old "OutOfMemory" one. So, I really don't know what to do!

I have 16GB (1600Mhz) RAM, a 2GB GTX 680 and a i5 3570! I'm pretty sure that the problem is far from being with my hardware, so now what?

Thanks in advance

Hello there. I finally managed to run it, both x256 and x512 version, but minecraft almost crash everytime I open it. By "almost crash" I mean it stop working ("not answering") for less than one minute in the x256 version and about 3 minutes or more in the x512 one.

What I did: I ERASED again every piece of Java from my computer. I noticed that in one moment I had windows accusing Java Update 45 and Update 21 installed at same time (?). I also reinstalled the development kit and minecraft.

Right now I have allocated 6144M (-Xms6144 -Xmx6144). The game runs really fine, but the x512 loading doesn't look so right. Is that a common thing to happen? Stuck for 2-3 minutes while oppenening the game? Do x512 textures really push this hard?

By using a large Xms value you are forcing java to allocate 6G of memory when it starts. The delay you are experiencing is the time it takes your system to swap out other processes and free up that memory up front.

With a smaller Xms Java will start faster, but may stutter later if it needs to allocate more.
