3770k overclock further than 4.5ghz?

Hardware Hub Overclocking
1

I’ve had my 3770k overclocked to 4.5Ghz at 1.225V for well over 2 years now. At the moment, I’m using a be quiet pure rock slim cooler but do you see any possibilities of getting a higher clock speed with a bigger/better cooler? (It’d be so sick if I can get 4.8 or even 5Ghz)
my specs:
i7 3770k 4.5Ghz
Kingston hyperX DDR3 16GB OC 2133Mhz (1866mhz stock)
MSI GTX 1080 Gaming X
EVGA 750W 80 plus gold
Thanks. :smile:

Edit:
Motherboard: ASUS P8Z68-V PRO
Temps:
Idle37-40C
Gaming for more than 2 hours: 58-60C
MAX load: 77-79C

More Edit:
Thermal paste: Arctic silver 5

Update: Got the Dark rock pro 3 as suggested by @Hako. Overall temps dropped by 10 C! Hoping for 4.8 ghz stable in the next few days.

Final Update (99% certain): Reached 4.7 Ghz stable at 1.28 V. Temps are great and nothing strange has occurred in the last 2 weeks. :smile:

You still have headroom in the Voltage area, though you didn’t mention your current temps.
If you delid it or get it delidded you might even get some more headroom in terms of temps.
A Dark Rock Pro 3 or a Noctua cooler will help keeping the temps down some more.
So yes there is a possibilty to get some more out of it.

Voltage can be pushed quite high on these Chips. To calculate the TDP you are using you do (Used Voltage/Original Voltage[1.025 if i am not mistaken])^2 * default TDP[77w]. That would make:
(1.225V/1.025V)^2 * 77W = 109.980369 W. Your Cooler is rated for 120W. So your Cooler should be Upgraded. A Dark Rock Pro 3 would be a good choice. Good thermal paste like thermal grizzly i would say is important as well. But your Motherboard should be able to push these Voltages as well. Asus Rampage Boards, Asus Sabertooth boards are generally good for Overvolting i would say. But don’t have too much experience with Ivy-Bridge overclocking/-volting in general.

Ah yes sorry.
Idle temp: 37-40C
gaming load: 58-60C
MAX load: 77-79C
Thanks for advice! :smile:

I just saw Dark Rock Pro 4 unveiled at CES. maybe good price for pro 3 :smile:

You might still want a new motherboard. Or keep Money handy when it you current fails, if you push too much voltage.

good point. thx :smile:

ordered dark rock pro 3. found a good deal on newegg. 4.8Ghz confirmed? :smile:

ok, got the dark rock pro 3 and managed to get it OC-ed to 4.8ghz. (stable 3 days so far) :smile:
Temps:
Idle: 39-42 C
intel XTU max load 30 min in: 84 C
voltage: 1.34 V

Doesn’t seem to go any higher than 65 C during games. normally stays around 60 - 62 C
Would you say temps are acceptable? or go back to 4.5 ghz for better longevity?

The temps seem very ok.
See how stable it is in the long run and if it’s unstable or you notice weird behaviour then step it down a bit.

it started to act strange. Now It’s at 4.7 Ghz at 1.27V. it seems very stable so far. :smile:
idle temp: 32-35 C
max temp: 75 C

I got off the OC train a few years ago, always would find strange things eventually and the benefits were pretty slim.
Now i just add aftermarket cooling to keep 24/7 max boost and call it good, no issues anymore.
