Ok, I am using 64 bit Java 7.51 and running a modified minecraft using MultiMC 5. In the option I set the minium ram to 1024 and the max to 2048. However when I go to run it, I get this:
MultiMC version: 0.2.1
Minecraft folder is: C:/Users/LordKhaos/Desktop/Portal/Games/Minecraft/MultiMC/instances/Meat/minecraft
Java path is: C:/Program Files/Java/jre7/bin/java.exe
Error occurred during initialization of VM Picked up _JAVA_OPTIONS: -Xmx512M Incompatible minimum and maximum heap sizes specified Minecraft exited with exitcode 1.
Why is it that I can't set anything higher than 512mb for the minium when I have Java 64bit? It's not an issue with my ram as I have 12gb of it.
Until I can get this fixed, looks like I will have to use the vanillia resource pack. Shame though, the Chroma Hills pack is amazing. Using f3 I saw that the Used Memory is constently at 90%, which seems to cause studdering. If someone could help me with this, I would be most greatful!
*edit* Well now, apparently even with Vanilla MC resource pack I'm still getting around 85-90% Used Memory
I say it needs to. It constantly being at 90% used along with the consent shuddering, barely playable. It isn't my rig either, because I can play a good portion of recent games released at near top settings.

Do you happen to have a 32-bit version of JRE installed? There may be a chance that it's trying to use it rather than the 64-bit version you're wanting it to use.
Nope, but I finally fixed the problem... Apparently I had -Xmx512m in my computers Environmental Variables, which overwrote what ever options I put into MultiMC.
This is an issue with certain external applications which may set your global java options to 500Mb for every single app. I think razer synapse is one of them.
Anyway, like it tells you, go to global java options here: http://www.itcsolutions.eu/2010/11/29/set-environment-variables-in-windows-7-for-java/
find the list that says _JAVA_OPTIONS
and delete the existing argument (-Xmx512M) and let the applications set them individually.

I have 2GB allocated but sometimes it uses 90% most times 70%
You're crash says your maximum is 512mb
So raising your minimum won't work..
unless you read my first post on this thread to raise your maximum.
