How To Speed Up Minecraft hack

I'll call this a hack because I'm going to use one program to change another in a way not intended by the author.

I've read guides on how to increase the memory usage of minecraft and they were complicated as hell, so here is my simple solution: Use MC Patcher to increase the ram minecraft uses. This works even if you don't or can't use HD textures.

This only works if you have enough ram.

1) As always: backup your minecraft.jar you'll find it in C:\Users\[Your User Name]\AppData\Roaming\.minecraft\bin\ The easiest way is to just copy and paste a new one. Windows will rename it minecraft - copy.jar automatically. If you need to change back just delete your minecraft.jar and remove the " - copy" from your backup.

2) Download MC patcher

3) Run it.

4) Click the "options" tab

5) In the "Java heap size (MB)" enter the amount of ram you want minecraft to use. 1 gig = 1024 MB, here I entered 2048 which is 2 gigs

6) Click the Mods tab and click patch.


If your computer is up to it you can now run HD textures but even if it isn't you've just increased the amount of ram minecraft will use which will speed it up - a lot!



  1. Does this work client side when playing on a server? I've been having problems with the game completely lagging for long periods at a time.

  2. I expect it would help, unless the lag is coming from the server itself or your internet connection, then increasing memory usage for the client wouldn't help much.

  3. For all the people out there i really dont like the "better grass" tab it makes the game look odd,but if it makes the game run better i guess its fine but just take this into consideration
