So me and my brother decided to make a modpack that only me and him will play, It contains a ton of mods, A TON, Starting with:

I didn't list the mods that I disabled in order to try to fix it, Also I used to crash of some odd reason, Sadly the logs are unavailable, Couldn't find it in the logs folder of the modpack, But it says that in the end of the log "java.lang.OutOfMemoryError" and it says that it fails to get the allocated memory, Or something similar, Although I allocated 1GB for the game, And I tried increasing it to 2048MB but the game immediately crashes because of the java.lang.OutOfMemoryError immediately, Although I have 4GB Ram and there is about 3 GB available and is unused, Despite that, Minecraft fails to use it all, I have Windows 10 64bit

Specifications of my computer (Perhaps it might help):
Intel core 2 duo 4.00 Ghz

AMD Radeon HD5450

4 GB RAM

Windows 10 Home 64bit

There is also a different issue I face, The game is slow when I play it, The movement, the breaking, Everything except the mouse movement is pretty slow, I do not know, But I think it is a side-effect for one of the mods, So I require an expert in mods to assist me in this, Thanks alot in advance.

Install 64 bit Java.

Already did.

Can you post your JVM arguments?

Can you post your JVM arguments?

-Xmx1024m -Xms256m -XX:PermSize=256m -Dminecraft.applet.TargetDirectory="S:\Curse\Instances\Spark Modpack 3" -Dfml.ignorePatchDiscrepancies=true -Dfml.ignoreInvalidMinecraftCertificates=true

I am depending on Curse to collect the mods, So that's why it is redirecting the minecraft directory to a different folder, And it never failed to do that.

Im afraid if your maximum amount of ram is 4GB you should really reduce the amount of mods and install optifine

Well, That's odd, Coming to the fact that no matter what I do, Minecraft refuses to use 2GB, While I am keeping track of how much memory is being used, I know there's always a GB that Minecraft refuses to use, Despite me setting it to 2 GB from the Arguments, Also I can play modpacks doubl as big with acceptable amounts of lag. So...

And you are sure u are actually using the 64 bit version (selected in the launcher)

Unfortunately I am more than just sure, But can you please refer to the instructions? Just so I make sure even more.. Yeah that's a thing..
