I'm looking into getting a new PC and i was just wondering how much i can overclock the I9 7940x with these specs

Motherboard - ASUS ROG STRIX X299-E Gaming

Graphic cards - 2 x MSI GeForce GTX 1080 Ti ARMOR 11G OC

Ram - Crucial Ballistix Sport 4x16GB 2400 Mhz CL16

Power supply - Corsair RM1000i Gold cert.

Cpu cooler - NZXT Kraken X52 RGB v2

Certainly overclockable, even easily, but these are monster CPUs, so good cooling is a must. A 240mm all-in-one isn't bad, but certainly people have pushed these high core count chips to 4.5+Ghz on all cores, with delidding usually, and beefy coolers.

Really your limiting factor is going to be temperature, so the first thing I would do is look at the core voltage under a full load at stock settings. You'll probably want to stay under 1.3 volts, with 1.35 being a more or less safe max value. And check the temperature as it does so.

As the CPU will boost to 4.4Ghz on its own with at least a single core, that frequency is certainly on the table. The problem is getting 14 cores to do it at once, this is going to consume way more power...

I would suggest using the PC for more than 2 months to see if there are any issues pop up. If there are no issues within 2 months, you might want to overclock it with some guides on YouTube. Also, Intel will void your warranty if you overclock it.

The problem is getting 14 cores to do it at once, this is going to consume way more power than 165W. (And you have to ask yourself, do you really need all those cores at that speed) If you are gaming or something, maybe try setting the max boost on 4 or 6 cores to 4.4Ghz and see if it can handle it. If you need all cores to go as fast as possible, probably going to need to invest in more cooling.

You will need to play with it to get a feel for the CPU and what it can tolerate.
