I have really changed how I do my overclock testing with motherboards. Every single test you see in the main section is repeated in the section that follows, including power consumption. As I test more products, a good picture of overclocking efficiency should emerge, which should prove interesting when it comes to those products that are 100% overclocking-oriented. I have grouped the results into sections here, and all Intel products are tested with 4.6 GHz CPU speed. Memory speeds vary depending on the platform's ability. I will report it here if a board fails to pass one of these tests, I need to increase voltages, or am perhaps allowed to drop voltages.
Getting the standard 4.6 GHz overclock out of my i7 4770K CPU was no problem at all, and simply enabling XMP had the memory running at 2666 MHz, though memory performance was really poor. I am not sure whether this is intentional or just a bug introduced by my flashing to the latest BIOS, but it is what I used to generate the numbers reported here since it is what I got out of the box. I use the same routine with all boards and have not run into this particular problem with other ASUS boards, which makes it appear intentional. But the ASUS P87I-PRO still performed decently, so I will take it as things stand if that is the trade-off for its incredible drive performance.
