Whoever was talking about vRAM is completely wrong, it has nothing to do with the amount you can allocate. I do have the same problem though and from reading the above solutions, installing 64bit java is the only correct one. If you have over 2gb's of RAM then the launcher will allow you to allocate over 1gb, but that is only if you have 64bit java. Also once you have fixed the problem, please don't allocate all of your available RAM to technic!
