BSOD 0x124 stable OC

[Guest]

I have a 4770k on Asus Maximus VI Hero. I've been running a stable OC at 4.3GHz with a 1.120V CPU voltage (manual). I used AIDA to stress test FPU and the OC appeared stable and good temperatures. I've been running this OC for over a week now without problems until today. Today, I launched my computer and after a few minutes of usage, I get BSOD 0x124 due to processor core.

I'm wondering if some of the more experienced users here know what could cause this to happen. Could this just be a one-time thing? I have turbo mode and EIST enabled; can this error occur due to an extreme over/undervoltage?

Additional background: my CPU core voltage was initially set at 1.100V but it could not pass the FPU stress test for more than 5 minutes, so I increased to 1.120V. Is it possible that the voltage is still not enough? After monitoring CPU-Z and HWMonitor for awhile, I've noticed that my core voltage fluctuates (min 0.08V, max 1.12V) but core speed never changes. Is this something to consider?

Thanks!

I've had oc's a month in that I found one program causes issues and have had to make modifications. 1 Week is ok but not necessarily bullet proof stable. You can try adding a manual offset. Just go into your bios and after you add it make sure to decrease/disable llc (load line calibration). Otherwise yes you will have to just up the vcore.
Adding a manual offset is simple. Run cpuz under load observe your actual vcore and write that down. Subtract the input vcore (what you have in your bios) from this. So for example, I have 1.145 Vcore. My actual reading on cpuz with a full load is 1.232V. 1.232-1.145 = .0852. However, in my bios I can only input .085 so that is my manual offset.

What this does is provide that little "extra" voltage to keep your system stable without technically having to raise your vcore. In practice it does but it's just an extra "push" to ensure stability so that your cpu can operate without it on less stressful applications. Hope this all makes sense and helps. Please let me know what questions you may have if any!
