Overclocking failed error message

[Jimstah87]

Hey everyone so I've been running my 3570k at 4.2ghz with 1.25v in sabertooth z77 for a while and every now and then upon cold boot it will fail to start and I get the error msg as mentioned above plus only have of my 16gb ram is being detected. I then have to reflash the bios yes using lateat to get it to notice all ram again and have to do my oc again. Its really annoying as it never blue screens and isnt unstable I just have this prob occur about every 10th time I boot the system. I have tried other older versions of bios also with exact same issue. Any thoughts I am completely bugged out on this one?

Sorry typo I was saying that it also is only detecting half the ram installed upon oc failure.

try not to overclock and see if the ram detection problem accrues again.

 

you have to find the problem by eliminating breaking points

Yes I have run it at stock and no the problem doesn't occur when it isn't overclocked

try swapping the RAM position

 

 

start to do memtest to see any RAM failure
