I'm saying you should find a used i5 750/760 to replace your current CPU because having a quad will help you more than more RAM.
Sorry I put a wrong core i5 series, mine is 750
so I'm guessing its safe to add/upgrade more RAM then. Again how about the timing though is it alright to have like different timings? like I mentioned earlier my current memory have 7-8-7-24 timing, if I'm gonna add more it probably won't have the same timing as my current memory.
