My coworker has the Asus ROG Strix X760E with four 32 GB sticks and he said upgrading to version 805 caused his motherboard to hang indefinitely (hours) on post code 0x0B until he removed two of them. I have the Hero and now I'm afraid to try 805 because I need 128 GB for work, even if it is a slower speed.

Edit: Worked fine for me. Reduced time to POST by a substantial margin, but no improvement in memory speed.
