Ok, guys, you gotta help me. I just recently bought a very nice pc, but if i try to play minecraft on it, minecraft freezes. I can get 600 fps just moving around, but after 3 minutes or so, it freezes for 5 minutes. Stock still, i have to ctrl-alt-delete just to free my mouse. Then it frees up again for a few seconds, then freezes again. I can play bf3 on ultra settings, and i only use drivers supplied by the company of the gpu i bought. I have 1 gb vram, nvidia gt650m, and 16 gigs of ram, ivy bridge i5 dual core @ 2.3 gigahertz... What's going on here?

Try allocating more ram

That would be a solution on my older rig, but MC is already using 1 gb of memory. >_>

Download the 64 bit version of java.
If you make minecraft use the 64bit version that won't happen anymore.

It is using the 64 bit version.

Have you checked the temps when gaming?
If you are not runningMinecraft on balanced/vsync this may simply be a case of it overheating,

Also, if it is only using 1GB on your system you might be using 32-bit Java.
You could try the 64-bit Java package: Java Downloads for All Operating Systems

I am using the right bit for the java package... It's not limiting it, i mean, i turn it down, and it goes down to 300 mb of memory, but it still freezes.

EDIT: Temps are normal. Nothing's hot or too cold.
