Tekkit "Out of Memory"

[pandith]

Launcher Version: 390

Operating System: Windows 8

Java Version: 7.0.510

Antivirus Program: AVG

Description of Problem:

Tekkit launcher works fine, I get into multiplayer fine, but about 5-10 minutes after I've been playing it freezes and takes me to a screen that says "Out of Memory". I know I can allocate more memory on the TechnicLauncher, but I can only have three different choices: 512MB, 768MB, and 1GB. After it goes to this screen I have to quit the game all together and start over, but then it just happens again.

I don't have a 32 bit system, so I'm not sure what to do about that.

(Just so you know, this only started happening recently, when we first started playing on this server this never happened)

I've tried uninstalling and reinstalling just in case it was something like that, but no dice

Quote tags doesn't work that way in this forum, besides you have buttons to choose from when you create a post.

As for the memory issue; what bits is your OS and java?

I apologize for not including that in the first post right away, I haven't posted in this forum before.

It's 64 bit OS and x64-based processor

And java? what bits is java?

I'm not sure how to figure that out, I've been looking everywhere and I can't seem to find it

google or ask a friend. I can't see your computer so you have to find that out

Control Panel -> Uninstall Programs -> will produce a list of all programs installed, including java, its version and bits
