I'm running Hexxit (using Sphax Texture pack x32) on the Technic launcher and when I start playing it runs smooth but after about 3 minutes it just says the whole Minecraft has run out of memory screen, and I'm wondering if I can add memory in anyway since I'm running 64-bit and can't do it from the launcher system specs:
Processor: Intel Core i3 SPU
Ram: 3.00 GB (3.80 usable)
System bit: 64-bit operating system
