So I have a bit of a problem, and it's driving me up the wall. I recently decided that I wanted to allocate more RAM to my Minecraft to increase my framerate when recording. I followed the layman tutorial, installed a 64-bit version of java, uninstalled all of my previous versions of java, and changed the -Xmx in the "Edit Profile" meni to 2G, just to test (I am using a laptop with 8G). When I did so, and clicked play, the launch exited, and I was greeted by the following error:

Since getting that sweet little error two days ago, I have scoured the internet in search of an answer, and tried every method I could find. Reinstall java? Done. Update drivers? Done. Even obscure ideas like moving the Java folder out of my Program Files and routing Minecraft to it. All done. I have tested the problem extensively, and have narrowed it down to only occurring when using a 64-bit version of Java (I tried both java 7 and 8). Everything still runs fine from 32-bit. Does anyone have any idea what the problem could be, and how to fix it?
Some additional details:
System: Windows 7 64-bit
RAM: 8gbs
Minecraft Version: 1.7.10
Mods: Optifine, and GLSL Shaders mod, both on the latest versions
Video card: AMD Radeon HD 7640g
Forge Version: Forge Mod Loader version 7.10.85.1240
Did you try updating your graphics drivers instead?
Next thing to try is to take off shaders. If you still have it without shaders, but only with optifine, then submit this report to optifine author. If this is truly some 32 v 64 bit java issue, he should know about it. If it doesn't happen with shaders, then ask shaders author what to do about it though you might just pick different shaders or go without shaders at all in that case.
This works! Thanks you very much Zohar! Only one problem, now I have a subsequent error xD I can open Minecraft just fine with 64x bit java, but as soon as I try and open my recording software (Dxtory) I get a very familiar error, namely the one I posted above.
As a side note, yes, I updated my graphics driver. That's what I meant I originally tried, but that was well before I fixed the original problem.
Any ideas? Recording is rather important to me, so it'd be a real pain if I can't use Dxtory anymore...
That I do not know. Keep in mind however that shaders are extremely intensive and that trying to combine that with yet another very graphics intensive app is going to be an issue unless you have really really good specs.
Anyone have an idea? I'd really like to be able to record using 64 bit Java. I tried downgrading my drivers because I heard somewhere that Dxtory had a problem with the latest version. This didn't help, as none of my regular programs would open...
