Okay, I went ahead and did the BIOS update first through EZ flash via the internet which brought me to BIOS 7901 and then through USB which brought me to 8002 (via th intrnet I was limited to 7901 strangely enough).
However I am facing an issue (I noticed it in version 7901 as well).
On BIOS 6004 I manually set my memory to 3400 as it is rated for that and it all worked fine.
However, after updating the BIOS the system was reset and when I now manually set my memory to 3400 and try to reboot I get the following error:
Your Memory Settings have been reset due to failure to boot.
Press F1 to Run SETUP.
I set the memory to auto which gives me only 2133Mhz. I am currently able to set it to 3200 but how can I get the maximum of my memory speed again? I bought 3400Mhz so I want to utilize it all like I always did.
