I currently have java v 7.10 64 bit installed with minecraft on windows 7 64 bit. I allocated ram to java in the control panel by adding -Xmx8192M to Runtime Parameters. I have 16gb's of ram but the thing is when I run minecraft v1.4.6 it's only using 1/4 of my ram so it's just using 4gbs of ram and not the 8gb I've allocated. I'm running Magic Launcher v1.0.0, with OptiFine 1.4.6 A2 and Sonic Ether's Unbelievable shaders V10 RC6. I'm also using a x256 texture pack. I'm running into errors saying I ran out of memory. I shouldn't have these problems since I have more then enough ram and it's saying it's only 4gb when I set it up to use 8gb. Can anyone help?
