Stable means your system is stable. Intel's default test isn't a good test for stability at a high overclock at all. It's probably not even good period because in order to be good with these CPUs, it needs to use the AVX instruction set, and Prime95 v27.7 and later does.
With Prime95's Blend test, there are 82 different FFT sizes and each one is very different and it takes about 24 hours to get through all 82. So, if your computer can run that test for 24 hours without any problems whatsoever, then you could call it stable. If you want an even more difficult test for your computer to pass, then use "Custom" in Prime95 (click it while the Blend test is selected). With this test, you get to tell Prime95 how much of your memory to use, and this makes it much harder on the CPU which is a good thing because the memory controller is on the CPU. 24 hours of Custom Blend would pretty much indicate true stability.
If you don't test your computer's stability at 4.8 GHz, then you'll be asking for trouble later on down the road. So, I hope you don't decide to give me the chance to tell you in a few months that I tried to warn you. ;)
