Overclock Intel Core i5 4670K with Hyper212 EVO

CombustLemons · Dec 28, 2014

Do you think that using the Hyper212 Evo I have any room to overclock to say 4.0Ghz? I want to but I am not sure if I can. My PSU is 600W Corsair 600M and my Mobo is a ASRock Z87 Extreme4.

Yep. The EVO is probably the most recommended cooler on the market. Many people achieve 4.5 on the EVO. You'll be fine.

If you've never overclocked before, read read read.

CombustLemons · Dec 28, 2014

Thanks I was worried and read read reading has been what I am pretty much doing. Do you think this guide ( http://www.tomshardware.com/forum/id-1808604/intel-temperature-guide.html ) is a good one to follow considering he has the same bios as me?

barto · Dec 28, 2014

That's a great guide. With guides, focus on the procedure/theory. That's the meat of the article. Each manufacturer will have special settings in the BIOS that you'll have to change once and forget. But the theory and testing is what is very important when overclocking.

Yes, as barto has said, it's an excellent air cooling solution. Just make sure you get a good case and fans to go along with it. Sound can be one of the biggest issues when overclocking. 600Watts of power supply is plenty for any single GPU configuration and enough will be leftover for overclocking.

Recommendations:
Any Fractal Design Define R series case.
Any Noctua fans that you fancy, but only their "Industrial" lineup will really match a black case.

Using Intel God's guide I was able to boot into windows but when I try to run Intel Burn test on standard I am reaching temps of 80 C and then on High I am getting temps of 80-90 C then BSOD. Those temps are scary. I have no clue what I did wrong. I really just wanted to go to 4.00 Ghz but I entered 44 as the cpu multiplier. What should I do?!

CombustLemons · Dec 28, 2014

Here is my setup from the A-Tuning Utility http://i.imgur.com/y45gdNX.jpg

CombustLemons · Dec 28, 2014

I undone what I did using Intel God's guide I think its back to normal but I still want to do 4.00 Ghz can someone please help me?

barto · Dec 28, 2014

Did you read the other guide I posted?

Set your CPU input voltage to auto and manually change the Vcore volatage to 1.3V with no offset then the CPU ratio to x45 and CPU cache to x40. Everything else should be on auto.

Test with AIDA64 only with the CPU/Cache/Memory boxes ticked
*In AIDA64 goto Tools>System Stability Test

If your temps are still at 80+ afterwards then you might have either applied too much or too little thermal paste or haven't seated the heatsink evenly. Alternatively your fan may not be spinning fast enough if you're 100% sure both of these are not the problem.

In order to check you should remove the heatsink and wipe off any thermal paste on the heatsink itself with a paper towel and rubbing alcohol(be careful no paper towel is left stuck to it), then reseat it evenly by tightening the screws in a cross pattern hand tight at first and then another half turn past hand tight with a screwdriver still going in a cross pattern.

*Tighten First *Tighten Third
*Tighen Fourth *Tighten Second

If you still experience high temps even with the CPU fan spinning at 1500-2000 RPM then you may have too little thermal paste or the CPU input voltage is simply too high. Try lowering the voltage by 0.01 until the system is no longer stable then bump it back up another 0.005 and run the test again. If there's still a problem then experiment with the amount of paste.

Once you get to the point where your max temp is 72-74 there's no more need to worry. If it's not possible then just lower the overclock and voltage appropriately until you're happy with the results.

I suspect your only problem is that you've set the CPU input voltage so high. That is not the correct voltage you should tinker with when overclocking the CPU ratio multiplier. It's generally recommended to not exceed 1.9V for input voltage even on water cooling, but it should be good on auto.

Do NOT attempt to raise Vcore voltage higher than 1.3 unless you're absolutely sure of what you're doing. You wont really get into the danger zone until after 1.4V and higher but it will degrade the processor faster when operating at a high voltage.

I will try this but do you mean max temperatures in Intel burn test or what because as of now on high test I am getting over 74 but never 80 keep in mind that is without any overclocking because I am did the first overclocking I did by resetting my bios to the default
Edit: Read your post wrong use Aid64

Derp64 · Dec 28, 2014

I mean the temps you get while testing with AIDA64 at those settings. Some stress tests are designed to put the CPU at absolute maximum workload which involves number crunching similar to the stress that Bitcoin/etc mining machines undergo. They're not real world representations as far as any kind of gaming is concerned and your temps will be 5-10C higher when running such tests.

CombustLemons · Dec 28, 2014

Aid64 has been running for about 15 minutes and the temps haven't exceded 74 C. That seems good. Do I keep the test running or does it stop on its own? Also just to verify I am using Aid64 Extreme Trial.

Edit: I have also been running realtemp during the SST and I saw that the first core went to 76 C max the rest haven't passed 64 C should I be worried or?

Derp64 · Dec 28, 2014

You must stop the test manually. It sounds like your problem has been solved and there's nothing to worry about with max temps like that. You can still attempt lowering the voltage a bit or increasing the CPU ratio multiplier if you want. I'm on a x48 cpu and x45 cache at 1.3V with my 4790k. If you're gonna stay at that you can try to get the CPU cache as close to the CPU ratio as possible for slightly better performance. Keeping it within 3-5x is good enough however.

EDIT: The results you're getting from realtemp would indicate that your heatsink may be seated unevenly or that there's not enough paste on it. Just try reseating it first and see if that solves the problem before applying more. You only want to have just enough paste to bridge the gap between the uneven surfaces/placement between the heatsink and CPU.

Derp64 :

I am extremely happy with 4.50 Ghz. How long should I run the test to ensure that my system is stable? Thank you so much for your help since I am new to overclocking!

Derp64 · Dec 28, 2014

Some recommend running the test overnight, but an hour should be sufficient enough. If you're not seeing any problems with general use afterwards then don't worry about it. Reminder to read my edit in the above post incase you missed it.

CombustLemons · Dec 28, 2014

Derp64 :

I saw edit about reseating the CPU cooler. I will probably try this if any more of my cores exceed 74 C after an hour of Aid64.

EDIT: I am replying from my laptop as the PC just blue screened with WHEA error. Going to check event log now.

Derp64 · Dec 28, 2014

It would probably help you seat it more evenly if you can remove the fan until after it's seated as well. Getting anything below 70C on air with high overclocks is very good and extremely exceptional at the price of those heatsinks.

EDIT: By the way I was wondering what paste you're using?

CombustLemons · Dec 28, 2014

Derp64 :

I believe the paste came with the Hyper 212 EVO but I may have some arctic silver somewhere. Also when checking the event log for the WHEA error when I went to Applications and Services > Microsoft > Windows > Kernel WHEA it showed no errors only operational events. What does that mean? I think the error was: whea_uncorrectable_error

Derp64 · Dec 28, 2014

I couldn't tell you anything about errors that isn't obvious. Maybe that one core overheated or the processor is just a bad apple and needs a little boost on voltage. Just try reseating and moving to 1.31V there shouldn't be much if any difference in temps.

EDIT: If it's still not stable at 1.35V try lowering the cpu multiplier to 4GHz and if there's still a problem afterwards you should seek help from Intel or another manufacturer once you determine the problem.

Derp64 · Dec 28, 2014

Using WhoCrashed might also help you determine the problem.

CombustLemons · Dec 28, 2014

If I just want the overclock to be at 4.00ghz what should I set the cpu ratio/multiplier to? 40?

Derp64 · Dec 28, 2014

You'd just set it to x40 and should probably bring the cache down to x35 with it. I hope you didn't damage it with the heat from when you were messing with input voltage or seating it in the socket.

CombustLemons · Dec 28, 2014

I'm worried now that something is damaged so I have decided to remove the overclock by setting the bios settings back to default.

Derp64 · Dec 28, 2014

It's unlikely to have suffered signifigant damage in such a short time especially considering the fail safe shut down mechanism, but even so if you did the warranty generally doesn't cover negligent usage outside of normal operation.
