AOpen AK77-333 (KT333) Mainboard

BIOS

The AK-77-333’s BIOS is fairly straight forward.  The main features you want to see is the CPU and RAM adjustments.  You can see below CPU frequency and voltage control window.  As noted earlier 1MHz steps are available for manual FSB changes or a preset bus speed table may be used.  Voltage adjustment for the processor peaks out at 1.85 volts.  As far as RAM tweaks, latency and command rate are adjustable.  Also adjustable is the DRAM clock setting, for up to a "PCI CLK x5" (33MHz x 5 = 166Mhz.)

     

One last major BIOS item is a save EEPROM option.  The EEPROM option allows you to save your BIOS settings after you get things the way you like them.  So if things get changed around, with one click you can restore your optimal tweaked setting you previously saved.

Performance

To test our board we will be using the Ziff Davis Content Creation 2002, Ziff Davis Business Winstone 2001, Mad Onion’s 3D Mark 2001 SE and 3D Mark 2000 v1.1, Serious Sam, and the benching standard Quake 3 Arena.  We have made several references to the AK77 Plus that is based around the KT266A chipset, so in an effort to show gains from the new chipset, this will be our comparison board.
