Stability for you own 24/7 use would depend on how demanding application you use.
But Primestable is a term, that the good old school OCing has been referring to minimum 8 hours of Prime stability.
Other stability tests are somehow new and unclear, but 1 hour OCCT, and 20 pass LinX have been used widely.

---------------------------
I have been playing with the 24/7 stability on x21 multi, and BCLK216 seams to be a major jump, at least for my CPU.

My CPU (which i really know it's normal behavior), acts like it has enough Vcore for 21x216, but adding other voltages won't stabilize the system.
Adding Vcore (within the expectations) doesn't help either. It seams to need much more Vcore from this point, but acts like it is missing something else.


I experienced the same behavior from BCLK226 with x19 multi too. I tried to get it stable @4.31GHZ (227x19), but never could stabilize it for 24/7, and couldn't figure what was wrong.

Both runs SuprPi32M and more .., feels fine and stable for light load, but gives BSOD 30 sec. into prime, LinX, or OCCT.

I think the MB plays a role in this behavior too, because the same CPU (and RAM) have been showing the same behavior on my good old DFI UT too, but on other BCLKS. I remember it was showing similar behavior when i was trying 19x216 (if i remember right). I never tried over 210x21 on that MB, and can't say much abut x21 behavior.

These BCLKs may change with new BIOSes too, I guess. I suspect some tweak on the MB would affects these BCLKs too, but I don't know what on this MB, yet.
