i5 4690k - Overclock temperatures and could I go further?

[Neildd]

Hi,
Are these temperatures fine? I've overclocked my CPU to 4.2GHz on stock voltage. Using the Coolermaster 212 EVO for my cooler, I peak at 75 degrees celcius on Small FFTs test on prime95 v28.5 (once hit 82 for a split second on one core on a really hot day), and about 60 degrees celcius on Blend. I am using Real tempt GT to measure temperatures. Whilst gaming (CSGO and Arma 3 mainly) I tend to peak at just under 60 degrees, around 58 or so on my second core which runs about 5 degrees hotter than the others. Idle temps are at around 30 degrees.

4.2GHz is the most stable I can go without adjusting the vcore. Is there any room for me to push further by upping the voltage?

Apologies how this has been asked multiple times, would just like to know for sure

Other specs:
Corsair Vengeance 2x 4GB 1600MHz RAM
MSI Z97 PC Mate mobo
Corsair 600W power supply 80+ bronze rated
Sapphire R9 270X GPU

Thanks in advance

Yeah there should be plenty of room, depending what you are comfortable with. What is your vcore voltage now? And yes your temps are perfectly acceptable, even during stress testing, being in the high 80's at full load is acceptable. If you are just gaming, then you have plenty of room to work with because you rarely hit stress levels like you would in those tests. My i7 is in the mid 60's when I game at 4.7 with a hyper 212 evo like yours.

You could go for increasing the vcore voltages and your temps whilst gaming are Very much alright.Just make sure you dont go to the extreme end.

Thanks for the quick replies. Under 100% load CPU-Z reports my Core Voltage to be at 1.081V; not sure if this is correct. I have it on Auto mode in BIOS (which I presume is the same as adaptive) and that reports 1.088V. Not an overclocking wizard so I'm not sure which is correct, or if both are etc.

You're welcome. If you are not a wizard and you value longevity the most, try to keep your max vcore voltage around 1.2-1.25. That will be the least amount of stress, voltage wise. Mine is at 1.34 V at 4.7 and I'm willing to risk it because 4.7 is a huge difference for me, from 4.6. If I didn't notice the difference as much as I do, I would just leave it at 4.6 with 1.27 vcore.

Basically you want to find out the max multiplier you can use with the amount of voltage you have. You have to increase voltage as you move your overclock up, or else you will not be stable. As you increase your overclock and voltage, your temps will get higher so you have to watch them and possibly adjust your fans as well. You can try moving it up to 4.3 at the same volatage now and test and if it doesn't work, then try moving it up to 1.15 at 4.3 and run a few tests. If stable, try it at 4.4, same voltage. If it's not stable, you can up your voltage in increments whatever you choose, depending how much time you have to invest. Each time you increase, means test and then reboot and change bios if it fails and such so it just depends how much time you want to invest.

When you get into the higher levels, you will most likely have to adjust your VCIIN voltage as well to get a stable ovreclock but it depends on your board. Mine's around 1.8.

Thanks a lot. I will start pushing my VCore up alongside my multiplier (42 was the highest I got on 1.088V voltage) and try and report back, should my CPU not fry!

You're welcome, you wont fry it unless you go super high voltage. I have profiles in my bios so I have about 7 or 8 saved all with different levels of overclock, so I can just switch whenever I want and it's really easy. If you don't have the option to save profiles, just make sure you write everything down somewhere, so if you are having issues, it's easy to just go back to one that works right away.
