And how does one go about fixing that then?
Stability testing To PRIME or not to PRIME that is the question!

Find the right balance between offset or set voltage and LLC. For instance if your voltage at Load line level 10 for e.g is 4.5GHz 1.35v at load and 1.3v idle the delta might be too great even without a load and stall the cpu.
The cpu may occasionally spike to the overclocked frequency without much load and since the LLC isn't much in effect 1.3v @ 4.5GHz may not be stable and it'll bsod, usually with a 101 or 124 error code.
Trial and error is the only solution.

I used to prime my systems for at least 12 hours but now i do 10 runs of IBT and a couple of hours max, this gives it a quick test then i just run as normal.
I found BC2 was always my best gauge on stability when i was running at max clocks now i dont even bother pushing my PCs, i just go as far as i can with stock volts...its been a long time since i spent weeks tweaking i would rather be using my PC now days rather than constantly tweaking.

Use Prime95 for stability testing and make sure its up to date enough that it uses AVX testing instances (most stressful on the CPU).
All IBT does is makes the cpu heat up, its not as good a stress tester as Prime95.
This cold be a combination of things, also depends on the BSOD code. Im guessing its BSOD 124, which usually relates to the PLL voltage o can be down to your combination of cpu power saving features. I.e speedstep, EIST, c3/c6 etc. If your having trouble try turning EIST off to make your VID remain constant, or use manuakl voltage as apposed to offset.

I use PRIME purely for heat testing. Seeing if you have a decent paste application/whatever.
Then normally run a bit of furmark, then some 3d mark. if anything weird such as extreme temps, over-volts show up then I notch clocks down a buit and try again.
But I have seen my PC pass 6 hours of prime, then immediately fail when loading a game.
These artificial testers are great for testing temps and volts are all with spec, but really not for stability. For this I always spend a few hours in a game with things like CPU-z, EVGA Precision X and M.O.D open to see all my temps/volts. Aslong as these are still OK after a short period of time I just keep playing.

Don't bother anymore with these artificial stress or torture tests. Most demanding thing I do I encode a video with Handbrake. So if it manages that, usually a 2 or 3 hour blu ray encode then I'm happy. Run BF3 64 man server online. Had initially stressed with AIDA64 for Haswell and was all find and dandy for a few hours but would crash when gaming.
I think its not a case of to Prime or not to Prime. I think it is better to use it as one of your tools in the overclocking arsenal, I have used prime and folding for stability testing in order to achieve stable overclocks. If your going to use the PC for gaming perhaps looping 3D mark is the way to go in achieving a decent and stable overclock.
