So today I updated my java 64x and just now tried to launch minecraft and it keeps saying that it couldn't add enough memory when I have a terrabyte of ram, I only have it set to 3 gigabytes, and it worked for a long time before the update. I had to disable the JVM arguments for allocating ram to be able to launch. Does anybody know why this is happening?

EDIT: When I try to launch with extra ram an error message appears and the launcher says:

Error occurred during initialization of VM
Could not reserve enough space for object heap

Can anyone help? A lot of times when trying to load a world or connect to a server it says out of memory. I really need the extra ram for minecraft.

Please help! I can barely play most of the time now!

Screenshots:

1. Error Message after trying to launch

2. What the launcher shows once it reappears

3. My JVM argument for 3 gigabytes that i've used for a while

4. a second message that the launcher sometimes shows

Do you have 64bit java and a 64bit OS installed, you need them to allocate more than 1.5G

OS (I am really bad with abbreviations)? I have had 64 Java for a while and once i updated it i started having problems.

OS = operating system

oh i just noticed your argument is wrong (i think, it may not be), put in a -

e.g. -Xmx3G

Well actually when i have Xmx3G the error on the final screenshot appears. When I have the -Xmx3G the first two errors appear.

I may have just figured out the problem. i have 64 and 32 bit java, 32 bit for certain things on websites that don't work with the 64 bit version, and 64 bit for minecraft. I was checking my fps without the extra allocated memory and saw that for some reason minecraft is running on the 32 bit version when I had it on 64 bit before the update. If I remember correctly 32 bit does not allow extra memory, so all I need to do is get it back on the 64 bit version.

And now i'm getting insanely annoyed. I used uninstallers and everything to remove java to re download the versions. the 32 bit version installed perfectly, but the 64 bit version will not stop saying that I have an older version not completely uninstalled and won't install the new version which is just so ANNOYING
