Minecraft Forums

I'm running 44 mods and keep getting lag spikes and random crashes. I have optifine, I have 16gb of ram with 6 allocated, I have 64 bit operating system with 64 bit java, I've tried everything I could find with no results. I know it's not my computer cause no other games have problems. If anyone has advice on this I would greatly appreciate it.
