I'm trying to exceed 4.8GHZ on a 6600k.
My setup includes: Z170a gaming M5 from MSI
6600k i5
Gskill trydent Z at 3200mhz
Corsair H60 AIO w/ ML120 fan
Corsair HX750w psu
I've removed the CPU delidding and replaced thermal compound with liquid metal ultra. I also added more liquid metal between the heat spreader and the heat sink.
Currently, I'm at 4.85ghz and cache at 4.75ghz. Core voltage is set at 1.415v and core frequency at 101.15. My XTU benchmark score is 1413 at 58c.
I have plenty of thermal margin. I'm pushing this chip to its limits but can't reach 4.9ghz. The system boots but freezes during the benchmark.
My question is: Can we exceed the maximum voltage if we have enough thermal headroom?
I know some users with LN systems achieve 6.5ghz, which would require even higher voltage for stability.
Thank you for all responses.

The CPU isn't the sole component that becomes hot under higher voltage, and your instability might stem from VRMs and other parts as well.
Those LN2 overclocks also help with cooling components like VRMs.
Can you push voltages further, as long as you have enough thermal capacity? Usually, yes... but it's not just about the chip's heat tolerance.

The CPU's performance isn't solely dependent on voltage; other components like VRMs also affect heat generation. Those LN2 overclocks you see help cool things such as VRMs too. You can try higher voltages if you have sufficient thermal capacity. Generally, yes—but it depends not only on the chip but also on the thermal headroom available.

The CPU might possibly exceed 1.52V if a suitable cooler is used briefly, but I can't confirm it won't happen. The motherboard's behavior remains uncertain. I definitely wouldn't try running it at such high voltages.
