Although the Intel Z77 Express chipset has been available for a while now we chose to wait until the official launch of Ivy Bridge to begin our reviews. After all the Z77 with Panther Point was designed to get the best performance when tied with Ivy Bridge so why not show that off first. To kick off our coverage of the Z77 we deiced to try out Intel’s reference design in the DZ77GA-70K. This performance desktop board from Intel is a great starting point and will give us the feel of how Intel meant things to work. So let’s get to it shall we?
The Test System and Comments - Our test system is built on an open bench. This has two effects on testing. First it allows us to see everything and also to setup and disassemble the test rigs quickly. Second it means that we cannot gauge the potential air flow found in a normal case. The air is pretty stagnant; some may say this is a great neutral testing method and it can be. However, it does mean that the temperature reading taken off of the components are not accurate to what an average consumer would see. This means that your thermal performance will vary from what we see here.
We did not have any issues with our setup of the Intel DZ77GA-70K after installing Windows 7 Ultimate x64 we were pretty much off and running. The only time we had any problems was when we tried to enable a VirtuMVP profile for PCMark7. Form some reason when we did this PCMark7 would crash or not display properly (the window would freeze until complete and then display the score). Eventually we had to uninstall both PCMark7 and the VirtuMVP software to fix this. Performance testing overview - Our testing is a little different than most. We combine both synthetic and real-world applications to simulate the types of performance common to the individual products. For motherboards this means that we run roughly six synthetic tests and two “real-world”. We will be expanding the real-world testing in the near future. But there is more to performance than just the raw numbers. As there are multiple components and sub-components on a motherboard there each item can have a distinct impact on the way the product will perform once you get it in your system. It is important to note not only the actual results but what they mean to you as a potential consumer. We will try to give this information to you. But we do not just cover the performance aspects that are measurable. We also talk about the components that might not have a direct benchmark. These are items like Audio Quality, ease of use and installation.
