Asus heeft een Q&Atje in elkaar gedraaid over de problemen die kunnen onstaan als je een TNT gaat draaien op een Asus P2L97 bord:
I have some problems running AGP-V3400TNT on the ASUS P2L97 rev1.05.
Along with the release of the Riva 128 TNT chipset based VGA cards, users with ASUS P2L97 rev. 1.05 or earlier M/B may find that they have encountered system hang-up problem with Riva 128 TNT VGA cards when playing 3D games. This problem is NOT caused by broken AGP sideband, and disabling the sideband protocol will not help. The reason that P2L97 rev. 1.05 or earlier M/B cannot support Riva 128 TNT is because Riva 128 TNT chipset requires a much higher power consumption at 3.3V than ordinary AGP chipset does, and the regulator on P2L97 rev. 1.05 or earlier M/B can only supply upto 2.5A of current at 3.3V. As a result, the system may run into problems when playing 3D games.
Generally, there are two types of regulator, linear regulator and switching regulator; linear regulator can supply at most 2.5A of current as switching regulator can provide up to 6A of current at 3.3V. P2L97 rev. 1.05 and earlier revisions use linear regulator and all other later M/Bs use switching regulator; therefore, P2L97 rev. 2.04 or later does not have this compatibility problem with Riva 128 TNT. At the time we had P2L97 M/B, most AGP VGA cards required only about 1.5 amps of current and together with the power required by other components of the M/B, providing 2.5A of current at 3.3V was pretty sufficient for the M/B to operate normally with combination of any AGP VGA cards. The newly released Riva 128 TNT chipset, however, by itself consumes more than 2.5A of current and, therefore, the regulator has to provide at least 4 ~5 amps of current at 3.3V in order to run Riva 128 TNT chipset based VGA cards properly
