Im at 100% sure, there are some 5 GHz stable chips...If you have some vith good VID. Or 8GHz+ LN2 have great potential at air too (if you have not sh*t cooler). And you knows, PRIME is not the right stability tets for Sandy, Ivy and FX CPUs, there is many bugs and issues. Example with IB or SB you are OK in PRIME, but crashed in games or sometimes in idle! I have this experience not only personaly. The different problem is with FX. You got errors, but your CPU is really stable in others test. And you get this error at stock too, so...? No, PRIME is not good optimized last months and you must hardly to find right version of this software. And I have not time, so I prefer now simply AOD or OCCT. PRime was good one, two years ago, no problems, no issues with flase errors or issues with "real" stability in test.
