the i7-2700k requires higher voltage than anticipated during the overclocking process
I'm currently trying to overclock an i7-2700k to somewhere in the mid 4 GHz range while remaining below 80°C and under 1.35V. At 4.3 GHz, the CPU crashed at 1.332-1.344V while running LinX, and the temperature was near 79°C. It may be worth noting that when LinX was running, the frequency would drop fron 4.3 GHz down to 1.6 GHz as if it was idling. I don't believe this is throttling because the throttle temperature is somewhere in the 90°C range. The CPU was stable while in-game and Prime95 blend, but not LinX.
I've seen others achieve much higher frequencies at much lower voltages than this, and I'm a little confused if there is much more I can do. Is there another voltage I should look to increase (VTT, IMC, etc.), or did I just get unlucky in the silicon lottery?
It seems like a setback in the silicon game. Also, a processor's overclocking capability tends to decline over time, meaning it might not reach the same voltage ratio performance it did when newer. My 4930k had to slow down its clock speed for stability after four years... Let me know if this helps!

Examine the temperatures of each of the four cores separately. If there isn't enough cooling for the CPU and one core operates at full speed while the other three run very lightly, then a single average temperature might show 79°C for one core and 50°C for the others. This could account for both the observed temperatures and the throttling to 1600MHz.
