RealBench and/or OCCT. Mostly, RB, though. P95 and Linpack are like the Furmark of CPUs when it comes to the unrealistic heat output.
Hell, I did 15min of RealBench to test my OC stability, and I haven't had a bluescreen since. That was about 5 months ago. Also, basic OS nagivation and web browsing is a great way of testing for stability, though you are more prone to corrupting your OS. That said, it's best to stress test on a clean installation because I've corrupted many OS installations due to bluescreens from stability testing. Making an image of the drive beforehand helps out a lot too so you can load the image after you're stable.
I have to agree. I always had used Intel burn test for previous OC testing. With my 4770k, I switched to RealBench. I played with the OC trying to get 4.5 Ghz stable and once I got through a couple runs of RealBench, it was stable. That was about two years ago. Video editing, gaming, clean OS installs multiple times etc. no issues.
