Well, the mem-parameter is mainly used in limiting the available memory, not the other way round. I would use that after you see all the memory, but the system is still slow.

I don't think that you have mentioned your graphics card yet. As someone mentioned, at least in 32 bit world that memory is taken away from memory under 4GB. That might not be your problem, but something related to bios might very well be. I would concentrate the effort to this before going on with the operating system. It might be helpful to also search Windows users experiences with 4GB on that motherboard.

I was going to say that while you have tested all ram modules separately, maybe the fourth ram socket on motherboard is faulty. But I understand that the problem (slow boot etc) occurs only when the fourth socket is occupied, but the bios reports the same amount of available memory?
