My concern is not whether or not you achieved 5.2 GHz, its what voltage it used to get there. This app is notorious for going well past what I'm comfortable with and I push the hell out of hardware. Even using it for manual overclock proved to be a death wish for me when it didn't write correctly to the BIOS and bricked a MOBO.
My advice, unistall that App if you can. Be prepared for a PITA getting rid of it if you dont have the tools for doing so. I recommend Ccleaner to uninstall, then go delete the folder it was in as its still going to be there, then back to Ccleaner and run the registry sweep to get rid of the orphaned entries there.
When you are finished with that, read one of the many overclocking manuals posted here and all over the net and do it from the BIOS.
