BIOS Parameters for Video Card. Part II

  • The parameter “AGP Master 1 Read” (AGP Read Synchronization) enables to add one more wait state while data reading. It has got two values: Enable and Disable. To increase the speed, this parameter must be switched off but it allows stabilizing the computer operation during its unstable functioning.
  • The parameter “AGP-2x Mode” enables to use the protocol of data transmission via AGP-bus of AGP2X-standard. This parameter has got two values: Enabled and Disabled. Enabling this parameter allows increasing the productivity as a standard bandwidth of AGP-bus that is equal to 264 MB/s is doubled by data transmission via both (upward and downward) edges of the main signals.
  • The parameter “AGP-4x Mode” (AGP 4x Supported) enables to use the protocol of data transmission via AGP-bus of AGP4X-standard. This parameter has got two values: Enabled and Disabled. This standard enables getting a small increase in system’s performance compared with AGP2X and it is used only in new video cards. It is not recommended to switch this parameter on for those video cards that support AGP1X or AGP2X standards.
  • The parameter “AGP Mode” (AGP Capability) enables to select the protocol of data transmission via AGP-bus. This parameter may have several values: Auto – automatic selection of standard, 1x – using AGP1X standard, 2x – using AGP2X standard and 4x – using AGP4X standard.
