Help overclocking my i7 4770k

I'd like to see my cpu overclock to 4.5 if possible.

I'm currently running 4.3 ghz at 1.2v with the base clock at 1x.

P95 temp max has been 80C after two hours. Any suggestions?

Also, I'm cooling with an h100i.

more voltage and a better cooler.

If I raise my voltage, my temp will surely go up though.

What cooler would you suggest?

yes when you raise the voltages you will get higher temps.

your only option for better cooling is a custom water cooling setup.

Alright, thanks!

What temp do you suggest I stay under on P95 for the i7 4770k?

Bump the voltage, crank up the fans and add +2 to your multiplier!
Your processor can handle approx. 100C before throttling :wahoo: 

If you run into a hard thermal wall, consider Delidding as a (somewhat risky) option to quickly lower your temps.

hahaha well... that does not sound ideal. Thanks for the tip. 100C? That sounds dangerous and I'm a broke college student so delidding is out of the question.

Honestly, oc should be out of the question.

Yeah, 100C is quite hot, but Haswell can handle the heat :) 
Not that I would recommend leaving it there for extended periods though.
Personally, I try to keep my 4770K below 80C MAX in day-to-day usage.

As a broke student, take the relatively cool 80C MAX/Stress temps and run with it!
The 200MHz bump from 4.3GHz to 4.5GHz will add barely add a noticeable performance gain anyways...

Once you are done with your studies and have a little cash; or about a month before your planned upgrade; then you can have some real fun overclocking your chip ;)

haha if I make it through alive and find a job, that is!

I'm gonna try a few more settings and see what I can do. Thanks for the help. :)

Any time.

Okay so I finally pushed my voltage to 1.215 with 4.5ghz.

Now my max with P95 is 86C. I don't like that number, but I feel like I won't ever hit that number either.

One thing I've been noticing is my first core is always about 12 degrees warmer than my fourth. Actually they're in descending order of warmth. Is that normal?

I was thinking tomorrow I'll take my h100i off and refix it to see if it may be sitting wrong.

Thoughts or suggestions?

Some variation is normal between the temperatures of different cores is quite normal, but 12C seems very large.
The first step I would take is the same as you already plan; reseat the CPU cooler with a fresh TIM installation.
If that does not fix the variation, it is probably a buggy temp sensor in the core and there is not much you could do about it.

Still, 86C in prime95 is still quite good!
I would not be worried about your temps at all at this point.
Not only is this within spec, it is also hotter than you will likely ever hit under normal usage.

Definitely reseat cooler. What method did you use to apply your thermal paste?

There was already thermal paste on the h100i.

One other question: How can I access my files from an old hard drive? Can I just plug it in to the motherboard and power supply and access it?
