Sinds ik een nvidia gforce gtx 460 op m'n systeem installeerde krijgt mijn geluidskaart (tc electronic konnekt 8, voor muziekproductie) het moeilijk. Als ik muziek afspeel kraakt en hapert het voortdurend. Heb al verschillende drivers zitten installeren, de pci latency in m'n bios van 64 naar 32 veranderd maar niks hielp zover. Latencymon zegt dit:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines executed by a driver running in your system appear to be executing for too long. Also one or more ISR routines executed by a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:02:28 (h:mms) on all processors in the system.
