i have double cold start on my motherboard: when i switch off my system and disconnected from power, and then switch on it happens. system starts, working about 2-3 sec, then switch off and starts again.
i dont know - is it a real problem, but it some worries me.
when i use auto overclock profile (2133 mhz, 1.2v , auto timings) double starts dont happend.
But it happends when i use overclock parametrs of my ddr: 3066mhz frequency, timings - 16, 18, 18, 18, 36, voltage - 1.35v.
i change only this parametrs.
*And it doesnot happend when i dont disconnect my system from power .
what should i also change to escape double starts?
Solved! Go to Solution.
It's a problem related to the mainboard. Latest official bios 3008 solves this issue. I suggest you to install this. I'm using bios 3008 and for my experience is good.
If you mean when you turn it on it will turn itself off (with 3 beeps if you have PC speaker attached) and then turn on again, it's normal, has to do with the RAM. Even my system with the same motherboard and G.Skill Flare RAM does that.
I have the same Motherboard, i believe it is a trick Asus use to minimise boot issues with higher memory frequency or something. Contact Asus and they can explain.
There's an option in BIOS on the DRAM settings for "Fail Memory Reset Count", set it to 10 and it'll never drop back down to fail safe settings, most I've had it reset on me is 3 times.
It's a known issue of the Crosshair VI Hero called "cold boot bug".

The OP "elmor" is a R&D Asus guy.
Edit: Please be careful, do not install the beta BIOS 0020 for now, it should contain the fix you are looking for, and it's more recent (rewrite based on new AGESA 126.96.36.199) but some people are having problems and a couple of guys have bricked the motherboard. It is better to install one of the two bios above.
I have your same CPU (1700X) and I recommend the bios 0052, which have both: "cold boot" fix and the "CPU temp offset" fix, that causes a wrong temperature reading after awake the PC from the sleep mode. It's beta as I said but works nice.
A possibly persistent error code it's a soft brick that could scare or cause trouble to unexperienced users, and that's not the only issue i saw, so I just recommend to load a more tested and secure bios that solves all the major issues.
That's why there is 0070 BIOS that fixes 0D code
But 0070 has multiplier bug again.
And unexperienced users should not load test BIOSes at first point.
Elmor posts beta BIOSes only in OCN forum for users that want to experiment and know they do it on their own risk.
ASUS propably would not accept RMA because of brick caused by unofficial BIOS.
Thank you. I use 0052 bios, as you said. you were right - CPU temp offset" fix work well. but i also have problem with cold start.
did you change any settings in bios after update it to 0052?
