The BIOS for this motherboard is typical for these motherboards, so we will only show key BIOS screens.
This is the main BIOS screen you see when you first enter the BIOS.
Here we see the AI Tweaker tab. Now, this has some very interesting settings compared to other dual-CPU systems we usually use here in the lab.
If you set the AI Overclock Tuner function to Manual, you can then change the BCLK Frequency, and the same is true for the CPU Ratio function, which can be set to manual allowing you to change the CPU Multiplier. However, with Xeon CPUs, you will not be able to change the CPU Multiplier.
This leaves only the BCLK Frequency that the Z9PE-D8 WS allows you to change. We will have more on this later.
Under the AI Tweaker menu, we can see the memory timing settings.
Next is the advanced menu.
Here we see adjustments that are in the CPU configuration.
The controls that you can change under the CPU power menu.
Here we see additional memory settings that you can adjust.
Here are all the SATA port settings.
This is the main USB port setting menu.
Here you can disable USB ports and the controllers.
