I've got a fancy new computer with a nice 32 Gig memory. But I can't get it to run on more than 1024MB of it.
According to Task Manager, with Skype on a call, Pandora running, the Wiki open and my Headset manager running, (the most I imagine myself doing with Minecraft open, really) I've still got over 27,000 MB of memory available. And I just want to run it on 8 gigs, for now.

I'm using the Magic Launcher (since I like Optifine's advanced options and zoom function) and if I try to run Minecraft with more memory, I get this:

MagicLauncher 1.0.0

The specified size exceeds the maximum representable size.

If I try any other amount, higher than 1024MB, I get the same exact error message, but with whatever memory amount I'm trying.

I've also tried the method listed here: http://www.minecraft...-for-minecraft/
But that didn't work either. Anyone know what I'm doing wrong?

You did put too much memory. That's all I know.

Or rather, Minecraft simply thinks I put too much.
I just need to know how to show it the error of its ways.

do you have 64 bit java installed?

I do.

Quote from webrosc

magic launcher is calling the 32 bit java



it should be calling C:\Program Files\Java\jre7\bin\java

32bit java can't handle more than around 1.5G

Huh. Guess I'll try re-installing the 64bit again.
Thanks.

And I just had to change the path.
Thank you very much.

It's still running at like 10fps though, and only using a small fraction of the available memory.
Dangit.
