BIOS

The red textolite color of the abit Fatal1ty FP-IN9 SLI mainboard PCB goes very well with white marking on it. The same bright color gamma was selected for the mainboard BIOS.

The remarkable thing about abit mainboards is that you don’t have to search for the overclocker-friendly section once you are in the BIOS. You will be immediately redirected to SoftMenu Setup upon BIOS entry.

The page is pretty well designed and contains a lot of useful info. It allows setting desired processor and memory frequencies and adjusting the voltages. FSB frequency is measured in quadrupled values and can be adjusted between 400 (100) and 3000 (750) MHz. The memory frequency may be set in dependence on the FSB frequency. In the Linked more we get few dividers to choose from: [Auto], [1:1], [5:4], [3:2], [Sync Mode]. In the Unlinked mode we can set the memory frequency to any value between 400 and 1400MHz. As for the PCI Express bus frequency, the supported range varies from nominal 100MHz to the unreal 200MHz.

As for the mainboard’s abilities to support different voltage adjustments, they are as follows:

  • CPU Core Voltage: from 1.325V to 1.7V with 0.025V increment;
  • DDR2 Voltage: from 1.8V to 2.1V with 0.05V increment and then until 2.5V with 0.1V increment;
  • CPU VTT Voltage: from 1.2V to 1.65V with variable 0.03V-0.04V increment;
  • NB Voltage: from 1.2V to 1.58V with variable 0.03V-0.04V increment.

I am not sure about the CPU Core Voltage, because 1.325V is the nominal value for our processor. Maybe this voltage parameter always changes from the nominal to 1.7V, or maybe you can add 0.375V to it and then the maximum will also change as the nominal changes, I am not sure about it. The mainboard user manual says nothing about it. In fact, there is not much about the BIOS parameters at all there.

Besides the frequency, the memory timings are another important parameter that affects the system performance. There is a special page in the Advanced Chipset Features section where you can adjust memory timings.

PC Health Status page will be of interest not only to overclocking fans but also to users working in nominal modes.

We can control the rotation speed of all four fans that can be connected to abit Fatal1ty FP-IN9 SLI mainboard and adjust the rotation speed of two of them: CPU Fan if there is a four-pin connector and SYS Fan if there are three pins only.
