True. When talking about single- and dual-channel mode, I think most people (including you when you're not in an argumentative mood) assume I'm defining performance as some version of throughput. But I agree, increasing the battery life is an appreciated bump on a different metric of performance. Do you have a guess what that bump might be? More than 2-5%?OneArmedScissor wrote:You need to qualify that question. Performance of what? Since you're talking about a basic laptop, you will increase the battery life a bit. That's a performance increase!wibeasley wrote: I was wondering about the performance hit from a single channel.
