Plenty Of Power
ASRock went with a 16-phase implementation here, which should be plenty for most air/water overclocking efforts.
On several different occasions, I've sought feedback as to why motherboard manufacturers are engaging in this "phase war," especially with P55, a purportedly mid-range platform. Of course, the answer is different, depending who you ask. According to ASRock, additional phases can help stabilize voltages at light loads. Conversations with Gigabyte suggest that more phases distribute loading more evenly, resulting in a cooler circuit. But Intel's upcoming P55 flagship only employs six power phases, and Intel insists it spent its time optimizing component layout, similarly affecting the thermal impact of its design.
We'll be digging deeper into the truths behind power later. Until then, look forward to the P55 launch early next month--we have tons of coverage planned!
