[Increasing RAM usage for tekkit]

hey, i'm getting some errors when i run tekkit, that it crashed because there was no more RAM for it to run.

so, i'm wondering, how do i increase the RAM usage for it? i know how to do it with Minecraft.exe

But i get confused when i try to do it on tekkit. I tried to do it on the launcher, but that didn't work either.

So basicly i'm wondering if there is a way to increase the RAM usage for tekkit and the other mod packs.

Thank you in advance

i know this is tekkit server forums, but i didn't know where else to post it, sorry
