4 Ultra ATA Drive Guidelines and Features 4.1 Ultra ATA Jumpers Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory pre installed, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
Ultra ATA Drive Guidelines and Features Single-Drive Cable System Board Device 0 (master) Blue Face Black Face Two-Drive Cable Device 1 (slave) System Board Blue Face Gray Face Device 0 (master) Black Face On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector. cables may be labeled “Drive 0” instead of “Device 0” and “Drive 1” instead of ✎ Some “Device 1”. 4.
Ultra ATA Drive Guidelines and Features 4.3.1 Device Classes In order to determine the best drive attach sequence, ATA/ATAPI drives are segregated into four different classes based upon the bandwidth demands they place on an ATA controller. The most demanding devices are in Class 1 and the least demanding are in Class 4.
Ultra ATA Drive Guidelines and Features The attach sequence rule may also be stated in table format: General Attach Sequence Rule* Sequence Description 1 The lowest class drive - bootable hard drive recommended. 2 If only two drives, the last drive goes here; otherwise the lowest class of the remaining drives. 3 If only three drives, attach the final drive here. If a fourth drive exists, attach the lowest class drive here.

F Memory AMD-Based Systems Computers equipped with AMD-based processors come with Double Data Rate-Synchronous Dynamic Random Access Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs). The memory sockets on the system board can be populated with industry-standard DIMMs. These memory module slots are populated with at least one pre installed memory module. To achieve the maximum memory support, you may be required to replace the pre installed DIMM with a higher capacity DIMM.
Memory The following processor bus frequencies are required for the system to run at the supported memory frequencies. Memory Frequency Required Processor Bus Frequency 266 MHz 400 MHz, 533 MHz, or 800 MHz 333 MHz 533 MHz or 800 MHz 400 MHz 800 MHz If a memory frequency is paired with an unsupported processor bus frequency, the system will run at the highest supported memory speed.
Memory The system will automatically operate in single channel mode or a higher-performing dual channel mode, depending on how the DIMMs are installed. ■ In single channel mode, the maximum operational speed is determined by the slowest DIMM in the system. For example, if the system is populated with a DIMM that is 266 MHz and a second DIMM that is 333 MHz, the system will run at the slower of the two speeds. ■ In dual channel mode, the DIMM pairs must be identically matched.
