The X79 Board to Silence Them All? X 79 Motherboards are aplenty and we’re bound to see countless revisions for at least the next 12 months. Much like with X58, each generation of boards coincided with better CPUs and higher overclocks. With X58 it’s hard to say what the ultimate board was as the later 990 X and 980X CPUs were such wonderful overclocking CPUs that they negated the differences in most offerings. Especially at such stratospheric speeds, it was merely a test of which board was quicker to overclock rather than which one wouldn’t make the speed at all. At least that was the case with the better CPUs. Our own attempt to find the ultimate X58 board didn’t end so well with several dead 990X CPUs hence you never did see that feature. So in order to avoid such a catastrophe, we decided to do this round up earlier rather than later. We managed to gather four motherboards, two in the high end and two which we would consider the value options. The INTEL DX79SI would be used to keep these boards honest, because the last thing any vendor would want is a motherboard that is no better than the INTEL board but commands a greater price tag. Our testing methodology was simple; Try and figure out which is the most efficient board, the easiest to overclock, the most feature packed board in terms of overclocking options and ultimately the best value motherboard in its chosen segment. This was easier said than done because the X79 32 The OverClocker Issue 18 | 2012 platform is inherently targeted at the high end so the boards will always be less about value and more about features and functionality. With each board offering 4-way graphics courtesy of the numerous PCI-E lanes made available by the CPUs we had thought of testing 4-way graphics on each board, but getting a hold of four 7970 graphics cards at the time proved to be anything but simple and while we initially did test with two 6970 Graphics cards in crossfire. We decided to re-do the entire feature using the beastly HD7970. During our testing, we also had to switch out CPU’s so what you are seeing here is actually our third attempt at this, because when we had almost collected all the results, our chosen 3960X CPU started to degrade in what can only be termed a “phenomenal” rate. From the chosen 4625 MHz we were using (37x125) to not being able to pass a single CineBench run at anything above 4000MHz, we had somehow managed to depreciate our CPU. As such we had to resort to the 3930K, however the results were near identical and moreover this CPU actually had a great IMC that was capable of close to 2600MHz with all four sticks installed. What follows on the next page is a breakdown of our thoughts on each board and ultimately the results when put through our standard benchmarks. We would investigate how much difference there actually is in the various implementations of the X79 chipset is any at all.
