I had problems, as I mentioned, with the cache when I tried using the "H".

I had to delete all files in the cache directory:
C:\ProgramData\Futuremark\3DMark Vantage\cache

I think my problem came because it was running and I had pushed it a bit too hard so it crashed. I think that this caused one of the cache files to get corrupted... and since it was still trying to use it... it wouldn't work.

So it wouldn't hurt to delete all files in that directory and then trying again.

I'm probably going to run the "H" test again soon at my current max stable. (I'm tired of people telling me that the Phenom II can't handle multiple video cards.)
