For your heat problem, that temp does seem a little hot. Do you have anytpe of thermal tape, or past on the CPU.?
Use artic silver for better heat transfer

Also I would be careful overclocking your memory unless you have some kind of heatsink or fan on them.
You can't attach a heatsink to ram. And if you were talking about memory heatspreaders, they don't do anything its just there to make ur memory look nice
