So, when i downloaded the Dalek Mod, and try to boot-up minecraft, it loads, and at some point, the free RAM goes critical, and throws me out with this crash report:

Any idea as to what shloud i do?

It's an out of memory crash.

Try assigning some more RAM to Minecraft. Dalek Mod recommends 2GB minimum

Error occurred during initialization of VM

Could not reserve enough space for 2097152KB object heap

Java HotSpot(TM) Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

I changed "-Xmx1G" into "-Xmx2G" and this happened.

How much ram does your computer have in total?

8GB of RAM.

Dayum, if DM needs 2 GB, then it is a hungry boi.

Can you show me a picture of the task manager of the second tab from left? Because it looks like you don't have enough ram remaining to give Minecraft 2 gb of RAM.

Okay update!
I added a variable named "JAVA_OPTIONS" with it's contents being "-Xmx3G" And it actually loded MC, but is still is crashing from insufficent RAM.

Here's the log:

Nevermind, it went back to:

Error occurred during initialization of VM

Could not reserve enough space for 3145728KB object heap

Java HotSpot(TM) Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

And it consumes max 150MB of Ram, according to task manager

Can you show a picture of it? It will help more. Also in the logs it says you have a 32 bit system? Windows 10 32 bit doesn't support 8 gb of ram but max 4?

Wait, what? I am on a 64-bit? Here's proof:

It's in polish, but it says i'm on windows 10, 64-bit OS, 64-bit processor .

 Hmm weird. Can you show the picture of the task manager example:

I need the second tab of the task manager and then the memory part.

 Oh wait, this tab! Here it is:

 Weird you got enough RAM remaining you sure you edited this to 2 gb:

Yep, it says "-Xmx2G" and it still gives me:
