BlackSparkle

Well whatever the problems was it seems to be related with x32 OSs, because after I reinstalled my Win as x64 then now i can allocate even 2gb with no problem

I dont know if i have to do new topic but i have same problem. Minecraft just wont allocate 1,5 gigs Computer info: Processor: Intel® Core i5-2450 CPU @2.50GHz RAM: 6GB (Usable 3,16 GB) System : 32-bit Video: nVidia GeForce GT 525M 1GB Launcher: 1.0.1.3 Also I dunno if it is important, but when i choose 1,5 gigs, then launcher closes, but when i choose 1 gig then it restarts automatically
