Abit Fatal1ty FP-IN9 SLI on NVIDIA nForce 650i SLI
Overclocking and stability
Let's take a look at the power converter. It uses a 4-phase power scheme, in which there are five 1200 mkF and nine 820 mkF capacitors.
All the overclocking tools gathered in the "SoftMenu" section:
First off, abit Fatal1ty FP-IN9 SLI allows adjusting the system bus speed within 100 to 750 MHz in <1 MHz increments.
Also note that the memory frequency is adjustable in the same way (see the previous page). Advanced users can set the FSB and memory speeds manually ("Unlinked").
There is also the "Linked" mode in which the memory frequency is adjusted automatically (depending on the FSB). Also, the user can select one of the standard multipliers of the memory frequency:
For those who are into high FSB speeds, there is a feature to adjust the CPU multiplier:
Another item is adjustment of voltage on the CPU (Vcore) within 1.3375V to 1.7125 V in 0.025 V increments.
Then, it is possible to raise voltage on the memory.
The adjustment range for Vmem is within Auto (1.8V) to 2.5V in 0.05-0.1V increments.
It is also possible to adjust voltage on the north bridge. Voltage can be applied within 1.2V to 1.58V in 0.04V increments:
There is another feature for adjusting voltage on the FSB within 1.2V to 1.65V in 0.03 - 0.07V:
Finally, the user can adjust the PCI Express bus speed within 100MHz to 200 MHz on the north bridge.
Now on to the practical overclocking. At that, the board showed decent results - a stable FSB speed amounted to 480MHz.
The board's capabilities are evidently higher, but further overclocking is impeded by the flaws in the BIOS, as well as rather coarse settings of voltages (i.e., a very large adjustment increment). We also note that while overclocking in the Linked mode we came across the situation that even the slightest FSB speed increase resulted in a "dead hang" of the system. You can resume the system operation only after clearing the CMOS settings. Since the board does not saving the BIOS profile, then you have to repeat tuning all the settings! It is advisable that programmers at abit implemented a feature for saving the BIOS profiles and "fixed" the Linked mode.
