As BigBadBeef says, you need to take an incremental approach to get there, but I would think that most 4790K's could get there with a 120MM air cooler.

Rule no.1 for OC: Don't just skip over to some ridiculous CPU frequency and voltage, you don't know how far you've come along the CPU lottery. Go one increment at a time and don't increase voltages until it gets unstable. Do it until you cannot stabilize the frequency under any circumstance or the temperatures fall outside of safety margin.

Overclocking is never a sure thing; two chips from the same wafer might have different limits or need different voltage. I would think that 4.2GHz-4.4GHz should be realistic even if you don't do so well in the "silicon lottery." If you hit the jackpot, 4.5-4.6.
Edit: 4.8GHz @1.375V might be attainable under water if you get a good chip, but is not an average, and I would not expect this on a 120mm air cooler.

Respectfultly, sir, you've been misinformed.

DelroyMonjo,

Core voltage above 1.300 is NOT recommended for 22 nanometer architecture, unless you're into competitive overclocking on extreme below ambient cooling. Informed and experienced overclockers, and the professionals here at Tom's, as well as many other websites who test and evaluate Intel processors and write review articles, all agree.

From the Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

" ... excessive Vcore and temperatures will result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl#q=Electromigration - which prematurely erodes the traces and junctions within the processor's layers and nano-circuits. This will eventually result in blue-screen crashes (BSOD), which will become increasingly frequent over time.

CPU's become more susceptible to Electromigration with each Die-shrink, so 22 Nanometer architecture is less tolerant of over-volting. Nevertheless, Vcore settings should not exceed the following:

-> Core 2

1st. Generation 65 Nanometer ... 1.50 Vcore
2nd Generation 45 Nanometer ... 1.40 Vcore

-> Core i

1st. Generation 45 Nanometer ... 1.40 Vcore
2nd Generation 32 Nanometer ... 1.35 Vcore
3rd Generation 22 Nanometer ... 1.30 Vcore
4th Generation 22 Nanometer ... 1.30 Vcore ... "

I appreciate your reply.

Some of our readers are very impressionable, and can be easily mislead. It's very difficult to correct misinformation once it takes root.

We encourage everyone to word their comments carefully, and take the time and care to be specific.
