The issue should be the resistor on the motherboard should be removed. If it works with one set of 4 then I would guess it already is. Mine doesn't take a long time to boot, but capacitors may be dying slowly on the motherboard. Also the ram you have may be bad. I've been finding more and more go bad. Even uniserver will tell you I sent him some on a motherboard that just were garbage that worked before I sent to him.
