BIOS

Abit is one of the few motherboard companies that provide great BIOS options for overclocking enthusiasts.  The Fatal1ty AN8 SLI came with pretty much the same exact BIOS layout and options as the Fatal1ty AN8.  The two are almost twins.

• VCore:  1.4v - 1.75v
• VDIMM:  2.5v - 3.4v
• DDR VTT:  1.25v - 1.75v, DDR/2
• DDR Ref Voltage:  -60 to default to +60
• CPU Ref Voltage:  -60 to default to +60
• Chipset Voltage:  1.5v - 1.8v
• HyperTransport Voltage:  1.2v - 1.35v
• LDT Multipliers:  1x, 1.5x, 2x, 2.5x, 3x, 4x, 5x, AUTO
• Memory Dividers:  AUTO, DDR200, DDR266, DDR333, DDR400, DDR433, DDR466, DDR500
• PCI-E Frequency:  100MHz - 145MHz
• HyperTransport Frequency (HTT):  200MHz - 410MHz
• CPU Multiplier:  4x - highest your CPU allows

Abit continues to provide memory timing adjustments to satisfy the overclocker's itch for tweaking memory speeds.  The great thing about the Fatal1ty AN8 SLI is that it now comes with higher VDIMM options.  Abit has heard the cries of overclockers and they are now supplying VDIMM up to 3.4v.  It is not as high as what DFI offers, but it sure beats out the rest of the competition.  3.4v is good enough for Winbond UTT memory and sure is more than enough for TCCD memory. 

One addition made in the BIOS is the higher memory dividers.  With a higher memory divider, you can run your memory at faster speeds without having to overclock the HTT megahertz.  I find these dividers to be quite useless.  If you are planning on overclocking your memory speeds, why wouldn't you want to overclock the HTT speeds?  I guess someone out there will find a use for these dividers.
