System Clocks section doesn’t do much: we can only change the PCI Express bus frequency there.
FSB & Memory Config section is extremely informative as always:
FSB frequency is measured in quadruples units and can change from 400 to 2500MHz (100-625MHz). In Unlinked mode you can set the memory frequency within 400-1400MHz interval, while in Linked mode you can only select one of the four dividers. Here EVGA nForce 750i SLI FTW offers broader functionality than its counterpart on Nvidia nForce 790i SLI chipset, which only had three FSB-to-Mem ratios to choose from.
You can see and change the current memory timings on a separate page:
System Voltages section is still very easy to work with and very informative. It reports current voltage settings highlighting safe settings with green and too high settings with red colors.
The voltages can be adjusted within the following supported intervals:
- CPU Core: 0.5V – 1.8V with 0.00625V increment;
- CPU FSB: 1.1V - 1.45V with 0.05V increment;
- Memory: 1.8V - 2.5V with 0.025V increment;
- nForce SPP: 1.3V - 1.55V with 0.05V increment;
- NF200 Voltage Level: 1.2V - 1.55V with 0.05V increment;
- GTLVREF Lane 0-3: from 0 to +160mV with 5mV increment.
Despite a few drawbacks, such as inability to control the rotation speed of a processor fan with a three-pin connector or partial profiles saving, the BIOS of EVGA nForce 750i SLI FTW mainboard is functional enough for successful overclocking.
