Ok, yes that fixed it. Thanks for all the help, and thank you for teaching me a few things.

Error occurred during initialization of VM Could not reserve enough space for 3145728KB object heap Java HotSpot Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release I am now getting this warning with -Xmx3G and the same for 2G I am running the latest update of java. ------- Edit: I also just down graded my java to see if it was just the recent update, and I still recieved the same error. Then I uninstalled Java all together and reinstalled again and I'm still getting this error.

-Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M this is the line of code in my JVM Arguments in my launcher. I try to change the Xmx1G to Xmx4G and that is when i get the Invalid Heap size at launch. And thank you, I hadn't seen Xmn in any research.

Logs (I can't get my dropbox to work, sorry) I try to add ram to forge and I get the error, "invalid heap size," and it shuts down the game. I've been looking on forums and youtube like mad and I can't find anything. I have been working on this issue for about a week now. I've tried running the jar file manually through the command prompt and through a .bat file and I get the same error. I am running windows 7, 6G of ram total, java has been uninstalled and reinstalled, I can't get the 64bit java (I know, I have a 64 bit operating system, I should be able to, but I can't get the download to work, and the 64bit firefox download, but I'll live.) I am running a self made modpack and Its overall performance has dropped to next to nothing. fps, memory maxed out in seconds, and I know all I need to do is add more ram. Ps: I don't need help with the mods, I'm just including them for extra info on your end. mods installed (all for 1.7.10) PS: I know I can add ram in the launcher but I don't understand the new JVM arguments line. I know the Xms in min ram and Xmx is max ram but the last part it gives me is Xmn, and that I don't understand. But reguardless, I get the heap size error help, please and thank you
