We will be outlining the MSI X99A XPOWER AC motherboard's performance with the Core i7 5960X CPU at its stock frequency (3.5GHz due to forced turbo). Overclocked performance will be outlined later in the review.

By default, the MSI X99A XPOWER AC motherboard applies multi-core turbo (MCT) and forces the 5960X to a constant 3.5GHz when XMP is enabled.

Although an A15 BIOS version was available for us to testing, we were very reluctant to gather results from a beta BIOS which could be a long time away from public release. As such, our testing was conducted with the latest public BIOS available – A10 – in order to provide the results that users can expect to achieve today.

MSI applies 1.07V to the CPU VCore when MCT is enabled.

Our typical testing procedure involves opening the motherboard vendor monitoring software and then running the benchmarks. Doing this with MSI's Control Center software on the X99A XPOWER AC resulted in lower-than-usual performance. The Control Center software seems to have some form of bug which reduces system performance when the monitoring tool is running.

As such we stopped opening the tool while gathering performance numbers and only used it to record system operating data.
