Resumen del manual
Again, ABIT makes it possible! ABIT is a company at the forefront of innovation. In the past, ABIT has developed SoftMenu™, which brought jumperless technology to motherboards. ABIT was also the first company which brought the Ultra DMA/66 technology to BX motherboards. ABIT is now bringing forth the latest technological advancement for motherboards: “133 MHz for All.” In order to meet the trend of higher frequencies on PC’s, ABIT is now equipping its’ products with 133 MHz capabilities. With special hardware designs and SoftMenu™III technology, ABIT’s BE6-II & BF6 can provide users with a stable PC133 system. Testing was completed by the NSTL, the leading independent microcomputer testing laboratory. Due to some limitations of other peripheral devices, we suggest that the user set up their system according to our instructions in the following sections. We trust you will enjoy the enhanced performance of our products. What is PC133 PC133 is the latest memory standard, increasing bus speeds 33% when compared to the PC100. In the past, 133MHz speed was only available when users overclocked their system. But users have previously found that they could not overclock their system to 133MHz successfully due to set CPU, chipset and memory restrictions. The highest CPU FSB clock was 100MHz. Chipsets and memory also only supported up to a 100MHz system bus clock. The 133MHz CPU front side bus is now available and the memory standard has been advanced to the higher 133MHz speed. The 133 MHz system is now ready for market. What is SoftMenu™ III technology? SoftMenu™III is ABIT’s newest BIOS offering. The ABIT SoftMenu™III technology not only lets users configure CPU settings easily, but also allows the user greater freedom in the setting of the CPU FSB (Front Side Bus) clock settings. How does SoftMenu™ III help to provide a more stable PC133 system ABIT SoftMenu™III provides the user with more CPU setting items, including settings for I/O voltage, PCI/CPU FSB Clock, AGP/CPU FSB Clock, AGP Transfer Mode and 120 settings for the FSB clock. All of these setting items are adjustable, thereby giving the user the power to adjust, according to system demands. This gives the user more choice and flexibility while running the 133MHz system bus clock on BX motherboards. We will detail these setting items in the following. • !!!!Unlimited Front Side Bus (FSB) In addition to the default settings for each processor speed, SoftMenu™III provides 120 user-defined settings on the FSB clock. Settings are at 66, 75 and from 83 to 200 MHz. 1 The settings from 83MHz to 200MHz can be altered in increments of 1, giving the user the power to find the best FSB setting, resulting in the best system performance. This technology equips ABIT’s products with the most flexibility and greatest compatibility to current and future specifications. • !!!!CPU Multiplier Factor From 2 to 8 (Increment 0.5). A total of 13 sets of multiplier factors support all current CPUs and allows for support of future CPUs. The CPU operating frequency equals FSB clock times the multiplier factor. • !!!!PCI/CPU FSB Clock ., 1/3, and now 1/4 is also a selection option. It correlates with the CPU FSB clock you set. For example, if you set the CPU FSB clock to 100MHz and choose 1/3 here, the PCI clock will be 33.3 MHz. We suggest you choose the ratio, which brings the PCI clock as close to 33MHz as possible. • !!!!AGP/CPU FSB Clock 1/1 and 2/3 options let the user adjust the AGP clock. We suggest you choose the ratio which brings the AGP clock as close to 66MHz as possible. • !!!!CPU Core Voltage 1.3 – 3.5 V manually adjustable but protected by SoftMenu™III from damaging the CPU. If the “CPU Operating Frequency” is not set to “User define”, BIOS will automatically set the voltage required by the CPU. • !!!!I/O Voltage Adjustable (8 sets, 3.2-3.9 V) This function allows the user to adjust the voltage supplied to DRAM, AGP, and the Chipset, thus greatly increasing the possibility of higher performance. If the “CPU Operating Frequency” is not set to “User define”, BIOS will automatically set the voltage required by CPU. • !!!!AGP Transfer Mode: This function allows the user to determine the capability of the AGP device. Selecting “Default” gives optimized performance. The video driver will decide the data transfer mode automatically. If the CPU FSB clock exceeds 125MHz, setting AGP Transfer Mode to “Normal” will result in a more stable system. • !!!!In-Order Queue Depth This item determines the command queue depth between processor and chipset. Selecting “8” gives optimized performance. Selecting “1” results in a more stable system. • !!!!Level 2 Cache Latency This item allows the user to set CPU L2 cache speed. Selecting “Default” gives the most stable performance. Smaller latency gives faster performance, but may cause system instability. 2 " Our Suggestion We strongly suggest that you use our default settings for each processor speed when you want to configure your CPU set...
