Gigabyte GA-P55-UD5 Review

Testing Methods

With the exception of SiSoft Sandra and Lavalys Everest, all of our benchmarks use real applications that give you a great idea of how well a product fares when performing the tasks you're likely to want it for. We are also focusing a lot more of our time on evaluating the overclocking potential and stability of the motherboards (and platforms) using a stress test designed to highlight any of the potential weaknesses that the product may have. That involves a gradually increasing amount of stress starting with Prime95 torture test on all cores and expanding to looping 3DMark06. This is to ensure that all parts of the system are stressed simultaneously over a period of time.

Most poorly engineered products fail within the first couple of hours, or even minutes, and along with the other test results this will allow us to make a conscious decision on whether a motherboard is worth your money.
