WinTimerTester is the name :) - the optimal result should be around 1.4mhz in this one.
Have to check the one which you posted.
Can you post screenshot from Latmon.
Thanks
Apologies for flooding the page heres for the asus and the old p67 gigabyte build (rip)

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 133.676207
Average measured interrupt to process latency (µs): 10.266911
