The minimum number you can enter is 0, the maximum number you can enter is 15. For best system performance, we strongly suggest you to set it to 0. User's Manual 3-18 Chapter3 3-4. Advanced Chipset Features Setup Menu The Advanced Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or is false, the motherboard will become unstable or you will not be able to boot up. If you don't know the hardware very well, use default values (i. e. The only time you might consider making any changes is if y ou discover that data is being lost while using your system. Figure 3-6. Advanced Chipset Features Setup Screen Shot You can use the arrow keys to move between the items. When you have finished setting up the chipset, press Esc to go back to the main menu. The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system has mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips. RDRAM Bus Frequency This item allows you to select the running speed for the memory installed in your system. We suggest you refer to your RDRAM specification before you change this item setting. Furthermore, when you set the CPU external frequency to 100MHz, only two options are available: 300MHz and 400MHz. CX6 Introduction of the BIOS 3-19 When you set the CPU external frequency to 133MHz, you can only choose 356MHz or 400Mhz. SDRAM CAS Latency Time: Three options are available: 2, 3 and Auto. You can select SDRAM CAS (Column Address Strobe) latency time according your SDRAM specification. RDRAM Device Napdown This item lets you set the power management for RIMM. When you select Enabled, it can reduce the power consumption of RIMM, but it will reduce the system performance at the same time. DRAM Data Integrity Mode: Two options are available: Non-ECC or ECC. ECC is Error Checking and Correction, when your memory is ECC memory, choose the ECC option. System BIOS Cacheable: You can select Enabled or Disabled. When you select Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Video BIOS Cacheable: You can select Enabled or Disabled. When you select Enabled allows caching of the video BIOS, resulting in better system performance. However, if any program writes to this memory area, a system error may result. Video RAM Cacheable: You can select Enable or Disable. [. . . ] 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 should know best what your system configuration is and your problem. [. . . ]
