On my 1.7.10 Minecraft, my allocated ram seems to slowly rise to 100% over time, and when it finally hits around 95% my game will start freezing, and eventually just stop responding, in the console, it says it cannot keep up, and it is skipping ticks. This problem seemed to arise after I installed Galacticraft, and it will not go away no matter how much ram I dedicate out of my 12gbs. I've dedicated up to 5, and it still finds a way to fill up, so i'm running off of 2-3 right now. I decided to reinstall all my minecraft files and run 1.8.3, and it seems my allocated ram still builds up over time, but a lot slower than it usually would, it would be around 40% used when I start my minecraft, and about 15-20 minutes later it would be at 65%, and still rising. How can I fix this problem?

I've been having a similar problem with my game. The allocated ram will start a say 26% raise up to say 80- 90% then back and restarts the cycle. While that's happening my fps drops to single digits. If i figure out what the problem is I'll let you know in case it helps fix your problem.

This is normal for Java Runtime Environment, the JRE that runs MC. This is the very reason it is recommended you DON'T assign too much memory to MC because once it peaks, the dump takes your computer's resources, and rather than it being quick and unnoticeable (as in very often and short dumps), it's long and laggy since it has a lot more to dump. As you use the memory in Java, it stores what you have loaded of the program until it reaches a certain point, then dumps all unused 'cached memory' of the program. Say your "Infinity Mod Pack" only requires 2G of RAM, but you assign it 10G, it will use the 2G, but then keep filling the rest of the 8 until it 'peaks', then it dumps. If on the other hand you assign it 2.5G it would dump a lot more often and be most likely unnoticeable rather than fill the entire 'RAM Bandwidth' while the dump happens, freezing the game.
Long story short: don't assign too much RAM to avoid the random 'lag spikes' from the JRE cache dump.
To the OP, from the sounds of it, it sounds normal to me. If on the other hand it reaches the peak and doesn't 'dump' the cache, then you have what is called a memory leak because it's not considered 'cached' therefore doesn't get dumped even though it should, eventually filling it up for good and most often freezing MC (yay for control+alt+delete). If that is the case, I would make sure to update your forge/FML and GalactiCraft as soon as the new releases come out, those issues are usually handled pretty quick by the wonderful devs. Hope this helps with understanding a bit.
I am experiencing the same issues, one mod known to cause memory leaks is MinecraftLoader 1.2 and 1.3. If you have this, delete it. It wont fix the problem, but you'll be able to play a bit longer without the RAM usage building up.
