EVGA nForce 680i LT SLI Motherboard Review – Cheaper 680i

BIOS Features

The BIOS on the new 680i LT SLI motherboard is nearly identical to that of the original 680i SLI motherboard.  This system is powerful and has tons of options for tweakers and overclockers. 

This is the main BIOS settings screen and you can see that NVIDIA has divided up the various options in correct categories with an easy to follow “flow” to adjustments. 

In our first system clocks menu you can see that multiplier adjustments are fully operational for processors that will allow it.

The PCIe bus can be overclocked from the 100 MHz default to 200 MHz.

The Hyper Transport bus between the two NVIDIA chips is also highly overclockable, but the benefits of such overclocking are usually pretty slim.

The HT bus can also have its multiplier adjust lower than the default 5x as well.

Here is one of the places the new 680i LT SLI BIOS differs from that of the full 680i: with SLI memory supported, but without auto-overclocking beyond the DDR2-800 speeds. 

Of course, you can still fully overclocking the memory yourself using the same methods available on the 680i SLI BIOS.  Here you can see the option of running either linked or unlinked mode; which refers to the ability to run the front-side bus and memory bus and completely independent speeds. 

If you decide to go with the linked mode, you can adjust the ratio that the FSB and memory buses communicate at.

The FSB speed can be manually adjusted from 400 MHz all the way up to 2500 MHz!

And as promised, the DDR2 memory speeds can be bumped all the way up to 1400 MHz!
