Re: Dual core vs. Quad core
Probably a voltage issue, most CPUs you can push a little with next to no temperature or voltage increase. However, it's the law of diminishing returns, you'll start to need a lot more power (thus more heat) for smaller gains. Probably worth lowering the clock speed like previously mentioned!
