BIOS Features
To go with the great motherboard layout and design, NVIDIA has continued to push forward with fantastic BIOS design in both features and layout.
You’ll be spending most of your time in here: the advanced chipset features menu.
The system clocks menu allows you adjust things like your CPU multiplier and all of the non-FSB clock rates.
Our engineering sample CPU allows us to set any multiplier from 6x up to 60x; your retail CPUs will likely be capped at their default multiplier.
The PCI Express bus speeds can be bumped from 100 MHz to 200 MHz in single MHz increments.
The HyperTransport connection from the north bridge to the south bridge can be clocked up to 500 MHz from the default 200 MHz.
The HT bus multiplier is adjustable too.
The FSB and Memory menu is where most of the magic of the nForce 790i Ultra SLI chipset is unleashed.
The EPP 2.0 setting allows you to allow the BIOS to auto-overclock your processor by the set percentage, or you can set it to Expert for full control.
This setting is really a favorite of most overclockers: it allows for completely independent control of the FSB and memory speeds or allows you to set a ratio like other chipsets offer.
The front-side bus can be increased from the 1333 MHz default all the way up to 2800 MHz if your processor can handle it!
The memory speed can go as high as 2500 MHz if your DDR3 modules are up to the task.
The memory timings are easily accessible.
