Technic only allocating 469MB

[thekian]

So here's the problem.
 
When I open the technic launcher I set the RAM allocation to 2GB and the pack loads (good so far)
 
When I am in a world however, it appears that the allocated memory is only 469MB and as it quickly fills up I get a big fps drop which then increases and drops again repeatedly even though it is set to 2GB and my laptop has 8GB which isnt used by anything else. I have included a screenshot of the allocated memory on the right and a screenshort showing the selection of 2GB allocated. My system specs are below. Thanks!
 
Processor: Intel Core i5 4200M (2.5Ghz)
Graphics: Geforce GT 740M (2GB dedicated graphics)
OS: Windows 8.1 64bit with 64bit Java

It took me 6 hours but I found the fix! 

 

What you need to do is go to control panel, then system and security, then system. 

 

On the left hand side is a list of stuff; click advanced system settings in the new window, click "Environment Variables" on the bottom right.

 

In the new window, find the variable "_JAVA_OPTIONS", select it and click edit then change the value to whatever amount of RAM you like. For example -Xmx4096M for 4GB, or -Xmx2048 for 2GB

 

Done.
