I have a 4770k and I'm about to get an H80i, I need overclocking help

[yotmam12]

I want to get it to ~4.4GHz, without going over 1.3 vcore and without having temps over 95C.
Should I do 44*100MHz or something else?

h80i is very capable and can keep the temps below 80C even on 1.3v!. increasing the multiplayer is the correct method as you suggest but use manual voltage and increase by 0.005v if isnt stable. do not go 44x100 at once, try stock voltage and try 40x100. stress test and see. if it fails then increase voltage. im pretty confident you wont need to pass 1.3v for 4.4ghz. also make sure you have a solid psu unit! and always constantly monitor temps! try to stay under 75c fot 24/7 also increase llc (load line calibration) to at least high - ultra high. it will help stability!

Use this as your guide to overclocking your 4770K. I used it as a guideline to overclocking my own 4770K (attached to an H80i), and achieved a rock solid overclock @ 4.2GHz. There's more to overclocking than just cranking up core voltage, as is explained in the guide.

Note that the H80i will most likely not keep your processor cool enough for stress testing if you crank it up much past 4.2-4.3GHz. I hit ~90c at 4.4GHz, 1.275V/Core, with slightly adjusted Analog, Digital, and SA voltages. For every day / gaming use you should be fine, though you'll want to keep an eye on it for extremely intensive CPU tasks.

h80i when on push pull confing im sure it can do way better than you are saying even at 1.275v. also the actual voltage needed also depends on the mobo! also warer cooling solutions suffer from increased ambient temps around the cpu area due to fan absence.so very good airflow is needed!

H80i fans are installed in a Push/Pull intake configuration, and in "Performance" mode through Corsair Link. Clocks are at 4.2GHz and 1.180V/Core. It was stress tested using RealTemp and Prime95 running a Small FFTs benchmarking test. Maximum temperatures reached ~80-81c for cores one, two and three; core four is always about ~10c cooler than the other cores (For some odd reason). Ambient temps are anywhere between 32-40c for light loads.

Just some numbers to go by. You might be able to pull better numbers than I've currently got, but for the moment it should give you an idea of what to expect. Keep in mind that you won't see high temperatures just browsing, playing games or what have you. I don't top ~60-65c usually on a day to day basis. Rather they only get that hot when I'm stress testing the CPU to verify stability.

As for overclocking, you should be able to get a clean 4.0GHz overclock without adjusting many, if any, voltages. Even then you'd probably be able to squeeze 4.2GHz without much fuss. 4.4 - 4.5GHz might be a task though.

Powerbolt, something about your ram, does it ran in dual channel mode in such arrengement? doesnt need to be o 1-3 or 2-4 slots?also about the core temps differences that occures due to the implementation of the memory controller in the cpu and also due not a perfect apply of the thermal paste on the cpu!
if you can run at 4.4ghz and 1.275v and hit 90c why cant you have a stable o/c with lower volts at 4.2ghz?

I've not had any trouble with memory as far as dual channel goes. My system reads all 16GB of it, unless it reads it but doesn't run dual channel.

@Chris987 Thanks for pointing that out. I must have read it wrong earlier when I was looking at my OC specs spreadsheet. Turns out MSi was right in that the voltage is approximately 1.18V/Core. I was looking at my 4.4GHz run which was cranked up to 1.275V. Oops.

ok, also about the dual channel try cpu z it clarifies that! anyway all cpu's aren the same so all atempts have different o/c results! even with the same hardware 😉
