I have a computer with 8GB of ram. With this I can play with a distance of 16 chunks (200+ fps), and now I want to try to play with far distance. However, I need to increase the RAM amount in the profile properties tab. When I set the ram to 2G, the game won't run.

Java settings for the profile: javaw -Xmx2048 -Xms1024

I have installed 64-bit java in my computer.

Why I can't set more RAM?

If it is useful: The profile is vannilla minecraft (no mods). It doesn't start.

  • What happens when it doesn't run? Do you get an error message or crash dump? What does it say? – fredley Jan 28 '16 at 16:46
  • @fredley Nothing shows up, just the game won't run. – spund3 Jan 28 '16 at 16:46
  • How does it "not run"? Does it cease running mid-load, or does it not even start? – user1337 Jan 28 '16 at 16:47
  • @user1337 It doesn't start. – spund3 Jan 28 '16 at 16:47
  • Are we talking about a clean MC, or modded? – user1337 Jan 28 '16 at 16:48

Looks like the launcher is using 32-bit Java instead. If you have the correct Java version installed, it should look like this:

Minecraft Launcher - Profile Editor Screenshot

where Executable option points to the 64-bit Java executable file (either java.exe or javaw.exe).

  • Maybe that's the problem. I'll look it. – spund3 Jan 28 '16 at 17:32

If you want to set the RAM to 2 Gigabytes, try typing "-Xmx2G" instead. If you ever seem to need more RAM for any reason, you can add more to the number; for example, typing "-Xmx3G" for 3 Gigabytes, "-Xmx4G" for 4 gigabytes, and so on.
