Boot failure after overclocking 2500k

Jonny Chee · 31 Dec 2012 at 20:52

I used the settings here:http://forums.overclockers.co.uk/showthread.php?t=18338090&highlight=2500k but 4.3GHz instead of 4.5GHz and it seemed stable enough using Prime 95.

However when restarting machine, I got the following error:

'The system has experienced boot failures because of overclocking or changes of voltages. Last settings in BIOS may not coincide with the current H/W states.'

Current CPU Speed: 4.30GHz
Current BCLK: 100MHz
Current memory speed: 1333MHz

It then goes into start up repair but fails until I load optimized CMOS settings. Then start up repair works and restores the system from a previous stable point.

Any ideas?

So, I slightly reduced the CPU VCORE to 1.9v and the DRAM to 1.5v and now have no boot issues (at 4.3GHz so far).

I'm still unsure as to what was causing the problems.

1.9V!!!!!!!!!!!!!!!!!!!! That is either a typo or you are melting your cpu.

It's actually happened again now, system failed to boot this morning. It worked fine for a day or so, including rebooting.

Does anybody have any idea what could be the cause?
