You can download a the latest version of CPU-Z
, which will tell you the BIOS date. You can head over to techPowerUp!
for the latest BIOS, beta and official. I would recommend trying the 702-2 one, which is what I am currently using.
If you don't want to use a BETA BIOS, you could use the 623 version off there. Just remember to reset your BIOS settings before flashing, or you may need to reset the CMOS.. as I've had to do a few times.
Chances are, if the computer reboots randomly, but often, it could be the memory OC. Sometimes it will pass fine, and others it won't. I've also had this happen in the past with certain settings, but it's never really affected my performance anywere.
