I5 4690K Stable Overclock - Opinions?

Guys,
I overclocked my I5 from stock speed, after I bought and installed an H60 Corsair Watercooling system. I managed to get the chip speed up to 4.4ghz, with 1.155v on Vcore, +0.4v offset on chip voltage and LLC on; it was later on tested with X264 for 6 hours, Aida 64 for another 6 hours and Prime for an hour, all passed (Prime did get very warm temperatures).
Going any higher than that on the clock speed would require Vcore over 1.175 (already tried) and my cooling system wouldn't handle the temperatures. I did not touch Cache speed or any other chipset values.
So what do you think, is it a good chip? what about the OC?
Thanks for passing by!

Edit: Didn't read the corsair h60 as cooler.
Thats a very nice mod you have mate. Temps on prime were running on the high 80s and even 90ish (degrees) when I had 1.175v so I decided to go as low as I could. On 1.155 I get an idle at around 28-32 degrees and max registered on HWinfo was 83 during Prime test; gaming doesn't go over 67 degrees. Keep in mind that I have a small case and a GTX 760 with stock cooler running around 75 degrees during gaming so its not exactly cold in there.-

stable at 4.4 on 1.55 isn't too bad. if i recall correctly i had to bump mine to 1.2 to get it past 4.2. as for the temperatures (No offence) i woulden't expect too much from a single fan radiator. My system reached 70 degrees ofter running prime overnight. try intel burn test. drop it back a little if it goes over 90. intel burn test is known for pushing high temps

I know I can't expect much, thats why I stopped at 4400mhz. Just replaced stock case fans with High Static Pressure 120x120mm Corsair fans; temps are much nicer now while gaming, not on idle though.-

1.44 V

Voltage skyrocket after 4.8GHz. Mine does fine with about 1.3V for 4.8... 8 threads. i5 are poor clocker on average. I've always had more luck with i7s. The HT requires more voltage and generate much more heat and I guess intel bin them a bit for that reason.

I was able to boot at 5.1 but I need 1.48V... you can see where this is going for a mere 100 MHz increase.

i have three of them in the front of my case. they are pretty quiet. 4.4 is were i stopped seeing huge performance increases, so be happy with that

my experiences with has well is that few go past 4.8

both myself and a few friends can't seem to get past it.

These are my 4690K OC results (inc package temp)
- Gigabyte G97N Gaming 5 ITX motherboard (memory @2400Mhz)
- Corsair H105 cooler w Gentle Typhoon at max 1100rpm
- 23C ambient, CPU idle temp 33C

4.2Ghz @ stock voltage 1.04V - 47C
4.5Ghz @ 1.14V - 54C
4.6Ghz @1.185V - 58C
4.7Ghz @1.23V - 62C
4.8Ghz @1.30V - 68C with fans at 1400rpm 66C

Wouldn't worry too much about it. You'd be talking minimal gains in most apps and games.. like 1 or 2% if that.
I'd say such money is better spend elsewhere (GPU, CPU, SSD).. but this ultimately depends on what you are personally after, what thing you'd like to improve foremost.

eg.

4.1ghz = 1.134v
4.2ghz = 1.187v
4.3ghz = 1.213v
4.4ghz = 1.268v

just a sample...

To hit 4.8 I just set it to the 4.5ghz profile, started with 45 CPU Ratio and drpped the voltage to 1.27 and worked up. Would reccomend just modding a profile as it already dials in settings for you

edit : i'm using a H80i GT cooler btw.. i think this would suffice on overclock.. just want atleast 4.2-4.4ghz
If you're after a moderate overclock, it's often good to look for what I call 'hitting the wall'.. So for my CPU.. between 4.2 and 4.5Ghz, I only needed very litte additional voltage to go to the next step. (~0.03V)
As you can see from my table above...from 4.5Ghz.. it started needing more (0.045 - 0.07V for each step. So for normal use, I stuck with 4.5Ghz.

By going in steps of 100Hz and you'll sooner get 'a feel' for your CPU. You can then also strike a good balance between temps & performance.

STABLE 4690k 4.3 GHZ

I have a fast, stable 4.3 GHz i5 4690K overclock at 1.2 volts. Never goes over 35c (95f).

System Specs: i5 4690K, Thermaltake Riing 12 CPU Cooler (blue LED ring), Gigabyte GA-H81M-HD3 motherboard (K Overclock turned on in Classic Bios settings (Important, will not actually apply overclocks well without this step), GSkill Aries 16 GB 1600 MHz RAM (blue) (XMP profile activated), Gigabyte NVIDIA GTX 1060 Windforce 6 GB Video card (overclocked), Raidmax Vortex V4 case (blue grille), 2x 120mm front Blue LED fans, 1x 140mm Thermaltake Riing 12 fan (Rear). 1x 80mm Blue LED fan (Top), EVGA 400W PSU. Because of the size and positioning of the CPU cooler, it is nearly perfectly lined up with the rear case fan. As a result, all the hot air from the CPU gets sucked right out the back of the case! :) However, I can not get the 4690K stable over 4.3 (4.4 or higher freezes the system and resets it to stock after manual reboot). I believe it is because my power supply is only 400W and most recommendations for a system with specs like these to overclock is 500W. I will eventually remedy this but for now, I am happy to have it faster than stock stable, and cool.
