Appendix E BX 133 Overclocking Guide

Notice: All suggestions are only for reference, ABIT doesn’t guarantee any hardware configuration beyond its specification.

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.” With special hardware designs and SoftMenu III technology, ABIT now provides users a higher chance for 133 MHz. We also tested some hardware devices with the 133 MHz FSB setting (Please see Support List.) And another reference test was processed by the NSTL, the leading independent microcomputer testing laboratory. All of these reports are obtainable for reference. We are glad to share these results to our users but won’t guarantee 133 MHz due to chipset or other devices’ limitations. We hope you will enjoy the feeling of finding out the best performance of your system.

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 BX 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 possibility of 133MHz 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. 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-definedsettings on the FSB clock. Settings are at 66, 75 and from 83 to 200 MHz. 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

1/2, 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, 3.2-3.9V)

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-OrderQueue 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.

"Our Suggestion

We strongly suggest that you use our default settings for each processor speed when you want to configure your CPU settings. We meticulously and repeatedly test these default settings. Adopting these settings will give you the optimum system for stability. The following table lists all of the CPU default settings.

Appendix F How to Get Technical Support

(From our website) http://www.abit.com.tw (In North America)http://www.abit-usa.com (In Europe)http://www.abit.nl

Thank you for choosing ABIT products. ABIT sells all our products through distributors, resellers and system integrators, we have no direct sales to end-users.Before sending email for tech support please check with your resellers or integrators if you need any services, they are the ones who sold you your system and they should know best as to what can be done, how they serve you is a good reference for future purchases.

We appreciate every customer and would like to provide the best service to you. Providing fast service to our customers is our top priority. However we receive many phone calls and a huge amount of email from all over the world. At the present time it is impossible for us to respond to every single inquiry. Therefore it is quite possible that if you send an email to us that you may not receive a response.

We have done many compatibility tests and reliability tests to make sure our products have the best quality and compatibility. In case you need service or technical support, please understand the constraint we have and always check with the reseller who sold the product to you first.

To expedite service, we recommend that you follow the procedures outlined below before contacting us. With your help, we can meet our commitment to provide the best service to the greatest number of ABIT customers:

1.Check the Manual. It sounds simple but we have taken a lot of care in making a well written and thorough manual. It is full of information that doesn't only pertain to motherboards. TheCD-ROMincluded with your board will have the manual as well as drivers. If you don't have either one go to our Program Download Area of the website or FTP server at:http://www.abit.com.tw/download/index.htm

2.Download latest BIOS, software or drivers. Please go to our Program Download area on our website to check to see if you have the latest BIOS. They are developed over periods of time to fix bugs or incompatibilities. Also please make sure you have the latest drivers from your peripheral cards makers!

3.Check the ABIT Technical Terms Guide and FAQ on our website. We are trying to expand and make the FAQs more helpful and information rich. Let us know if you have any suggestions. For hot topics check out our HOT FAQ!

4.Internet Newsgroups. They are a great source of information and many people there can offer help. ABIT's Internet News group,alt.comp.periphs.mainboard.abit, is an ideal forum for the public to exchange information and discuss experiences they have had with ABIT products. Many times you will see that your question has already been asked before. This is a public Internet news group and it is reserved for free discussions, Here is a list of some of the more popular ones:

alt.comp.periphs.mainboard.abit comp.sys.ibm.pc.hardware.chips alt.comp.hardware.overclocking alt.comp.hardware.homebuilt alt.comp.hardware.pc-homebuilt

Ask your reseller. Your ABIT authorized distributor should be able to provide the fastest solution to your technical problem. We sell our products through distributors who sell to resellers and stores. Your reseller should be very familiar with your system configuration and should be able to solve your problem much more efficiently than we could. After all, your reseller regards you as an important customer who may purchase more products and who can urge your friends to buy from him or her as well. They integrated and sold the system to you. They should know best what your system configuration is and your problem. They should have reasonable return or refund policies. How they serve you is also a good reference for your next purchase.

5.Contacting ABIT. If you feel that you need to contact ABIT directly you can send email to the ABIT technical support department. First, please contact the support team for the branch office closest to you. They will be more familiar with local conditions and problems and will have better insight as to which resellers offer what products and services. Due to the huge number of emails coming in every day and other reasons, such as the time required for problem reproduction, we will not be able to reply to every email. Please understand that we are selling through distribution channels and don't have the resources to serve every enduser. However, we will try to do our best to help every customer. Please also remember that for many of our technical support team English is a second language, you will have a better chance of getting a helpful answer if your question can be understood in the first place. Be sure to use very, simple, concise language that clearly states the problem, avoid rambling or flowery language and always list your system components. Here is the contact information for our branch offices:
