Please don't top-post. Anyway, if you're not seeing all 4G, then you are most likely running an i386 kernel/release and not amd64. In order to use 4G on a 32-bit (i386) install, you need to include: options PAE In your kernel config. Note that memory access with PAE is much slower than if you were running a native amd64 kernel/install. Regards, Josh
