IPKYOU788

The server has 2GB of RAM, that's the client... I just haven't messed with java arguments yet, I'm just trying to get my modpack + server up and running.

Nevermind, fixed it, config error.

Hi, I'm getting a crash whenever I join my server on a custom modpack I made. I can play singleplayer just fine. Could anyone help me? Thanks. ---- Minecraft Crash Report ---- // I blame Dinnerbone.

I see that it's IC2, here's a link to my modpack, it's 1.5.2: https://dl.dropboxusercontent.com/s/z0x4k562rivjz0f/PotatoModpack.zip?dl=1&token_hash=AAGMZ6-iK39fdgAGJpUWk43Y_Mu1Xvit9xPW7V_FLoaXWA

In the top-right hand corner of your launcher, there should be a little gear which is your settings. In the settings menu, there is an option called "Memory:", and you can change that to however much RAM you want.

Fixed it, I was using a later version of IC2.

I see your problem, you need a coremods folder. You put some of the coremods in your regular mods folder.

Your modpack is a .rar file, and it has to be .zip. Re-upload your modpack in ZIP format, and it should work.
