De ennek nem OC kell, hanem fesz.csökkentés. 
First of all, the 7870K runs happily off lower voltages than the default 1.487V for 3.9GHz and I was able to run 3.9GHz from below 1.2V. I tested 4.0GHz and 4.1GHz at 1.2V without problems, but crashed at 4.2GHz, which required 1.3V to run. I didn't try any intermediate voltages so this is only a rough dividing line.
I planned my 4.5GHz-4.9Ghz series using clearance multiples (43x105=4515, 44x105=4620, 44x107=4708, 45x107=4815, 45x109=4905). The first three worked fine: 4.515GHz=1.43125V, 4.620GHz=1.45V and 4.708GHz=1.475V; but 4.815GHz crashed with voltage raised to 1.5375V, even with the LLC settings set to extreme, so my 'Hello Boys, I'm Back' poster will have to stay unposted and I will have to leave off testing this chip any further until Asus update the BIOS and/or someone lets us know what the upper limit for CPU voltage is.
Azért felpöccintette 5 GHz-re is.
