But the history of motherboard vendors adjusting and tweaking features for performance goes further back than that, such as variations with the base frequency from 100 MHz to 104.7 MHz with the Spread Spectrum, leading to increased performance on systems that can support it. We were the first outlet to break out features such as MultiCore Enhancement, way back in August 2012, which led to higher-than-specified all-core frequencies, or in some cases, outright overclocks. One of the common themes I've noticed throughout my time at AnandTech as our motherboard editor and now our CPU editor is the lengths to which motherboard vendors will go to in order to get increased performance over the competition.
The Old Fashioned Way: Spread Spectrum, MultiCore Enhancement, PL2 So to try to clarify matters, here’s our take on the situation. To be sure, this kind of tweaking isn’t new, but recent events have lead to no shortage of confusion over what exactly is going on, and what the ramifications are for AMD Ryzen processors. By doing so, they are able to increase the processor's power headroom, and ultimately allowing for higher performance at the cost of higher thermals. To this end, it has recently come to light that motherboard vendors have been taking advantage of a setting on AMD motherboards to misrepresent the current delivered to the CPU. And as a result, we sometimes see methods of increasing processor performance that clearly deliver on their promises, but perhaps at the expense of thermals or longevity. This insatiable drive for peak performance, however, means that some of these tweaks and adjustments can start to skirt the lines of what is ‘in specification’. Either through end-user overclocking or motherboard vendors tweaking settings to improve their stock performance, at the end of the day everyone wants better performance, and for a multitude of reasons. Where there is a will to get extra performance out of a CPU, there is often a way.
