[Split] PowerSpectrum Unit Test

BTW: Steve, I think your card has downclocked or something.

Here's mine, 480 @ 820MHz (Win7x64):

That's interesting. Normally I am running at 860 MHz, with the voltage at 1.05 VDC.

9500GT would be a great double check of the theories so far (Mod3 64 thread should be the right choice & extremely close to stock for that one)

Just- 
   - chuck the exe & dll into a new folder somewhere easy to get to, such as C:\TEST
   - Open a command window (Start->Run->CMD.EXE),
   - change directory to that location ( cd \TEST )
   - run the test  ( powerspectrum4.exe > results.txt )
   - wait for it to finish & look at results.txt

At least they crunch fast.

Jason G:
Ah Huh!  Memory clock

820/1640/2088 1.138V, that's about as hard as I can reasonably push it without going to water.

This particular test kernel is memory bound, so that'll be the difference.
