I cannot really help with AMD Systems, but I can advise you to not use Easytune to overclock, it should all be done in the BIOS
What Model is your Ram and how much of it do you have, in what configuration? Should you be using more then 1.8V maybe?
As for your load/save Easytune question. You must have auto load last save on next reboot checked, and you must of course have always run on next reboot checked as well for it to run at startup.
If you are not the admin of your OS then you may need to make yourself an admin, not sure as I am always admin
If you would like to continue to try to use it please be sure you are using the latest BIOS for your board and the latest Version of Easytune >>>

If you do flash your BIOS, do not use @BIOS. Use Qflash, here is a guide I wrote on how to use Qflash >>
If you would like some more help I can point you to some Forums with AMD Specific sections. Not trying to not offer you help or anything, I just have limited AMD Knowledge
