The diagram is provided as a visual guide to help you install the socket processor and may not be an exact representation of the processor you have.

  • Page 23: Heatsink Retention Frame Installation

    2.5 - Heatsink Retention Frame Installation After you are done installing the processor, you should proceed to install the retention frame and heatsink. The CPU heatsink will ensure that the processor do not overheat and continue to operate at maximum performance for as long as you own them.

  • Page 24: Thermal Interface Material

    2.6 - Thermal Interface Material There are two types of thermal interface materials designed for use with the ® ™ Opteron processors. The most common material comes as a small pad attached to the heatsink at the time of purchase. There should be a protective cover over the material.

  • Page 25: Heatsink Installation Procedures

    2.7 - Heatsink Installation Procedures 1. After placing backplate and interface material under motherboard place heatsink retention frame on top of motherboard. Align plastic retention bracket screw holes with CPU back- plate standoffs. Tighten screws to secure plastic retention bracket. Repeat for the other side.

  • Page 82: Glossary

    Glossary ACPI (Advanced Configuration and Power Interface): a power management specification that allows the operating system to control the amount of power distributed to the computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure. AGP (Accelerated Graphics Port): a PCI-based interface which was designed specifically for demands of 3D graphics applications.
  • Page 83 Bus: a data pathway. The term is used especially to refer to the connection between the processor and system memory, and between the processor and PCI or ISA local buses. Bus mastering: allows peripheral devices and IDEs to access the system memory without going through the CPU (similar to DMA channels).
  • Page 84 BIOS, it is a ROM chip which can, unlike normal ROM, be updated. This allows you to keep up with changes in the BIOS programs without having to buy a new chip. TYAN’s BIOS updates can be found at http://www.tyan.com ESCD (Extended System Configuration Data): a format for storing information about Plug-n-Play devices in the system BIOS.
  • Page 85 device hooked up to each IRQ line; doubling up devices on IRQ lines can lock up your system. Plug-n-Play operating systems can take care of these details for you. Latency: the amount of time that one part of a system spends waiting for another part to catch up.
  • Page 86 (or overlapped) across multiple hard drives, but offers no fault-tolerance. RAID level 1 is known as mirroring, which stores the data within at least two hard drives, but does not stripe. RAID level 1 also allows for faster access time and fault-tolerance, since either hard drive can be read at the same time.
  • Page 87 UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without a proper UltraDMA controller, your system cannot take advantage of higher data transfer rates of the new UltraDMA/UltraATA hard drives. USB (Universal Serial Bus): a versatile port. This one port type can function as a serial, parallel, mouse, keyboard or joystick port.
