Today we have one of ASRock's second wave X299 motherboards, with improvements mainly made to the power delivery system. When most X299 motherboards were introduced, most of them had one issue; they couldn't easily handle an overclocked Intel HCC CPU. Intel's High Core Count (HCC) CPUs have more than 10 CPU cores, and they can pull over 500W from the motherboard's VRM when overclocked to 4.4GHz or higher.

While many people can overclock their CPUs to 4.4GHz easily, they typically are throttling due to internal protection mechanisms built into the VRM. So, like many vendors, ASRock went back to the drawing board, and they have now released much stronger motherboards designed solely to handle an overclocked Intel HCC CPU.
