Possible values of an option:
From [66.6Mhz] to [75.0Mhz], [Auto]
The option description:
Gives the chance to specify working frequency for bus AGP. Normal value — 66 MHz (66.67 MHz if to be more exact). Bus AGP acceleration normally does not practise: the scanty scoring in high-speed performance does not justify possible problems with stability of operation of the videocard. On the contrary, at overclocking try to fix frequency of bus AGP on a mark in 66 MHz.
