Open your startup script. There should be an option that says -Xmx1024M change the number to however many gigabytes you want to allocate multiplied by 1024. You may have to install 64-bit java to allocate more than x ram if you're using 32-bit. You should leave some ram for the system or else it may crash. I also suggest adding these option but it's not necessary.
-server -Xms1024M -Xmn512M -Xincgc -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:+UseCompressedOops -XX:+AggressiveOpts -XX:+CMSClassUnloadingEnabled
If you have a multi-core processor you can also add -XX
arallelGCThreads=1 with 1 being replaced by how many cores you want to allocate to the server. (Replace the '' with a colon and a capital 'P')

All you need to do is create a Notepad file (as indicated in the tutorial).
Where the numbers are, put in the amount of ram you want (5120)-just replace the 2 numbers in the line of code with 5120
Replace Minecraft server (at the end) with "direwolf20.jar"
When you save the file, save it as run.bat, making sure that the drop down menu (below the naming line) is set to all files.
"C:\Program Files\Java\jre7\bin\javaw.exe" -Xms5120 -Xmx5120m -jar "direwolf20.jar"
