BIOS Settings & Test Setup
Like the high-end P67 motherboards we had tested previously, these Z68 boards came with enthusiast-class BIOS settings. While the BIOS interfaces remain similar to their P67 counterparts, with both ASUS and MSI opting for a graphical user interface with mouse support, Gigabyte kept to its Hybrid BIOS approach with an old-school interface that should be familiar to long-time users of Gigabyte boards. As mentioned before, Gigabyte has added the new TouchBIOS utility that works within Windows and effectively gives the same amount of control over the BIOS.
Besides the voltage settings (we listed some of the more important ones in the table below), the ASUS and MSI boards also support the integrated graphics output capabilities of the Sandy Bridge processor. Hence, you'll also find options to enable the Virtu software layer and even tweak the graphics clock speed of the processor. The Gigabyte board however only has the discrete option, so it's hardly any different from its P67 equivalent.
|Model||CPU Voltage||DRAM Voltage||Other Voltage Settings|
|ASUS P8Z68-V PRO
||0.80 to 1.99V
|1.20 to 2.20V
||0.75 to 1.7V
|0.90 to 2.60V
|MSI Z68A-GD80 (B3)||0.80 to 1.80V
|1.108 to 2.464V
The same test configuration that we used for all our P67 testing has been replicated for this Z68 roundup. Note that the Z68 boards were installed with a slightly newer version of Intel's chipset drivers. Besides the three Z68 motherboards slated for review, we have also thrown in one of our best performing P67 motherboard, the ASUS Maximus IV Extreme as a reference.
