Flex 5000A.
ver. 2.0.8
Sample rate 192K, 1024 buffer
Windows 7, Pro, 64bit
PC- Intel E8400 3ghz cpu, 5G RAM, no wireless card to router, wired direct
to router for internet
no IRQ conflicts.
Average cpu % <20%
Just installed Windows 7 64 bit and having an issue with audio cracks or static
during network internet traffic. Such as during lookup on qrz.com with DX-labs
Pathfinder program, during internet lookup the cpu percent jumps briefly to 80%
with audio cracks in PowerSDR. DPC's remains less than 200ms throughout.
Also, if using the internal keyer for CW, the CW wpm will slow waaay down and
miss elements. This audio crack also occurs on Spot Collector program
traffic from the DX C uster. Uninstalled virus protection program and
no change.
Any ideas on what settings to look for? Perhaps additonal RAM, or update
motherboard drivers? New faster PC? :) Have 5g ram now which is
recognized by Windows 7 64.
Fortunately, I have two HDs in the PC, so reverting back to Windows XP and all
is well on XP, 32 bit. But would like to keep experimenting with Windows 7
64bit.
