I have figured out my problem. I am expecting the flash to do what it is not designed to do. My faulty thinking was about high speed sync. I was thinking it meant the flash would fire in rapid succession, did not matter the lighting situation. I now have found out, it only refers to shutter speed, not burst speed.
High speed sync is not for shotting multiple frames. You take one picture. Set your camera's sync speed to 320*, then you can set your shutter speed to 1/4000s or whatever you need. I usually shoot outdoor flowers at 1/4000s and f/11. Makes for a great flower shot with a black background, even in daylight.
Good luck.
