Abit BE6-II Motherboard - Page 5

Soft Menu III
The BE6-II comes with two ways to set the CPU speed: (1) DIP switches; (2) Soft Menu III (setting CPU speed via BIOS screen).

When the DIP switches are used to set the CPU speed, Soft Menu III is disabled. The DIP switch option is probably useful for vendors that put together systems with the BE6-II but want to prevent the casual user from messing up their machine in the BIOS.

For the hard-core overclockers, Soft Menu III is what I consider the ultimate overclocking solution. It allows the front-side bus to be set at 66MHz, 75 MHz, 83 MHz and anything between 84 MHz to 200 MHz in 1MHz increments! The PCI divider can be set at 2,3 or 4. The only weak link in the whole arrangement is the lack of an AGP ˝ divider (which is something dictated by the BX-chipset itself).

Comparing the overclocking stability of the BE6-II against the BX6-R2 – both were able to overclock my P-III 450MHz up to 600MHz (133x4.5) at 2.3V core voltage. However, the AGP bus was running way out of specifications, which resulted in crashes the moment I tried to overclock the TNT2 Ultra. This was not a good performance compromise for me, as my other major past time at the moment is playing Unreal Tournament.

The TNT2 Ultra was stable enough to overclock on both motherboards at 581 MHz (129x4.5). This for me represented the optimum overclocking point. Notwithstanding this, I would normally run my CPU at a saner frequency of 558 MHz, this comes from having to pay for your CPU– there have been a few cases reported in the internet of the CPU L2 cache being fried at 581 MHz.

There was virtually no difference in WinBench 99/CPUmark and WinBench 99/FPU WinMark between the BE6-II and the BX6-R2 as you would expect, at the same CPU clock speed.

Conclusion – the BE6-II is stable to overclock. There is however a natural limit to how far your can push your AGP card, a limitation that is imposed by the BX-chipset itself.
