If you want to check it out go to
https://www.asus.com/pl/Motherboards/ROG-MAXIMUS-XI-HERO/HelpDesk_BIOS/ then choose tab "Sterowniki i oprogramowanie" and then click "BIOS & FIRMWARE" tab.
DRAM stability must be super improved since it's stated twice lol!
Update: it's updated on US site under Bios & Firmware too if You are interested. I will check this bios out after I get home from work.
