Do you have any other programs running at the same time that use java. As that is most likely causing it.
It will be most likely because of that then. To check if you change back to default pack then see what the ram usage is.
I used to use the 128x sphax pack and would use 6gb of ram but I had only 4gb assigned to ftb.

This is usually a problem with Java itself.
The launcher is most likely using the correct amount of allocated RAM. However, the actual Java process is using more RAM, because it thinks it needs more than you gave the launcher.
If you go into your Java control Panel, select the Java tab. Under Runtime parameters, you can restrict Java to only use what you want it to use.

I think I would go for "-Xms3072m -Xmx3072m", assuming you have 8 gigs physical memory available. If you have 4 gigs go for 1536 on both. If you're interested there's also a (sometimes very thorough and in depth) discussion at forum.feed-the-beast.com/threads/jvm-arguments-for-modded-minecraft.28994/
