| Hvordan køre man 100 MHz AGP??? Fra : Niels Nørregård Hans~ |

Jeg vil gerne vide om det er en driver eller bios opdatering der skal til
for at køre med AGP 2.0??
Desuden hvordan kobler man dette Sideband til??
SE nedestående....
Jeg har en PIII 500 på abit BH6 med et ASUS V7700 deluxe og kunne godt tænke
at få det til at køre optimal..

Transfer rate: The clock frequency used by AGP is 66MHz disregarding to the
mode being used (1X or 2X in AGP1.0, 1X, 2X, or 4X in AGP2.0). Under 2X
mode, data is latched at both the rising and falling edges of the strobe
signals. The strobe signal is running at 66MHz, just the same as clock
signal. The data is being transferred at 133MHz because data is latched at
both edges. The ¡§ideal¡¨ transfer rate for AGP 2X mode is
133MHz*4=532Mbytes/sec since the bus width is 32-bit wide. Note that for all
the aforementioned modes, the clock frequency is fixed at 66MHz, and 4X mode
is available in AGP2.0 only. Furthermore, the 2X mode DOES NOT equal to
AGP2.0.
Sideband signals: The 32-bit bus in AGP is used for both address and data.
While transactions (reads or writes) are running, commands (address +
commands) cannot be issued for queuing until the transactions finish.
Sideband addressing prevents this by separating the commands and
transactions paths. So, the transactions can keep on running without
intervening with commands, a higher transfer rate could be expected. Note
that 2X & 4X modes apply to sideband signals also.

Asus fraråder at køre med side-band enabled, på V7700...
