Windows .exe Max memory setting not working

[thealbinosmurf]

I am currently on a win 8 Pro machine with 6gbs of ram and vanilla minecraft works great and I had set java to have a -Xmx of 3072 and -Xms of 1024. When using the ftb launcher and trying to set the max memory any higher than 1024 and trying to run it the launcher closes but minecraft never starts.

You're not alone, I am using vista and when I tried increasing the max memory i had that same issue. I just assumed it was because the memory was unavailable for whatever reason and changed it back.

Needs more 64-bit Java.

Well that's nice and all for people who use 64 bit PC's, but those with 32 bit apparently cannot go beyond the 1024 line, which is kind of bothersome.

I had 64 bit but I think it was java for 8 I installed during rtm days and I just needed to update and had not thought that was the problem so thanks for making me think of it

I would strongly advise not directing people to third-party providers of JRE; unless you can be certain the source is trustworthy, like java or oracle sites, you're opening yourself up to potentially serious vulnerabilities.

Still not working!!!

Well after some reading through the forum, it seems this was already an issue before the official release, so I have to suspect that this is a launcher issue and not exactly an issue with Java itself.

I had the same problem but now it work. You have to install java 64bit normal if you download it form their homepage it's 32bit here ist 64bit http://www.java.com/en/download/manual.jsp

 

[Oyeahoyeah880]

I have it and still not f*** work....

 

[Meldiron]

I have it and still not fucking work....

Did you uninstall java 64bit and then reinstall it?
Not beeing able to set max memory over 1GB have so far been a good indication on that your not running the 64bit java edition.

 

[Oyeahoyeah880]

I did,and im runnin:Java 7 UPdate 9.
