I know but the only way of me being able to play with those mods is going through OptiFine and I already posted a bug report on their Github. I don't have a very good pc. So if i want to play with mods(i'm trying to play with 246 mods right now) i need optifine and if i have optifine some mods don't work. I can only hope that they can solve it.
These are the specs.
Edit: The cpu is dual core and ram is ddr3. 240 GB ssd.
