Hey there,
I have been having a Asus Z87 Sabertooth with a i7-4770k for about 2 months running stable at 4.2GHz and 1.2V Vcore.
Recently, I added an internal (active) NZXT USB hub to hook up some more internal USB headers and my Corsair AX760i.
Don´t know if this has something to do with anything.
Everything seem to be working for a week.
Then, about 3 days ago, I noticed that my mobo BIOS wasn´t even listed on the Asus website as "First release", so I updated (from 0801) to the latest BIOS (1204) after restoring default settings.
Everything seemed to work fine. I decided to give my CPU another OC try since I couldn´t really push it far.
But I never set it to any dangerous voltages or something. Once I tried a VCore of 1.3V at 4.3GHz and did a stress test at which it just reached about 87°C. So, nothing dangerous here, either. Also, tried the auto OC in the BIOS once but didn´t use the settings.
However, since then I have serious problems. Without any obvious reason and while (semi-)idling, my system just turns off. No BSOD or something, it just turns off.
When I try to power it up again, the fans start spinning but then it turns off instantly. Then (without doing anything) it would usually turn on again, fans start spinning and then it turns off again. Sometimes it does this 2 times, sometimes 4 times. Sometimes I hear a "beep" before it turns off, sometimes not.
Resetting BIOS via jumper or pulling the battery doesn´t work.
Only thing I can do is unplug the PSU for about 10-20 minutes and then it would turn on normally.
I currently disabled the OC in the BIOS and have everything set to default (except for loading the XMP profile).
So, now I have several theories and several questions.
1) The new BIOS is just crap. Can I downgrade to an older version? Also, any idea where I can get the 0801 BIOS?
2) The internal USB hub is causing the trouble. I´ve read on the ROG forum that some Z87 have some problems POSTing with active USB hubs connected. Which is why I currently have it completely disconnected and am hoping this is it.
3) I fried my CPU. I mean, I know every OC comes with risks but have it running 1.3GHz for only 10 minutes or something.
Any other ideas or suggestions?
