for me it was i belive ARMR or ARM , i do not remember , when it was Activated , that was not a problem , BUT when i activate also like saving stage S4 +S5 THEN i got the dobble boot
Yes i was talking about APM conf ... the Erp Ready , ok that is what does cause the dobble boot here for me but if that dosent change anything for you , i have to say in this case i have no other idea then what could be the problem then
Maybe this is off the mark, but I've had my Rampage 5 Extreme do this semi-frequently. In my case, it was the BIOS trying to overclock the CPU and sometimes it just wouldn't "take" so it reboots at a lower frequency. If I recall, my system was attempting to run at 4 Mhz, when (I think) stock is 3.7. I've notice when I run CPU-Z that my CPU does indeed run at 4 Mhz sometimes, but the turbo boost only kicks in when needed. I don't recall what setting in the BIOS I have that makes it try to boot at 4 Mhz, but it's not a major problem for me now, so I haven't even been into the BIOS for several months to check.
