Overclocking a i5-4670k

DeltaRecon2552 · Feb 5, 2014

I have a stock cooled i5-4670k. I let AI Suite III overclock it for me at first to start. It put it to 1.2 vcore and 4.2 ghz. It crashed about 10 minutes into PlanetSide 2. So I rebooted and put my Vcore to 1.21 with a deviation of 0.001. I now run PlanetSide on Ultra at over 70fps in combat and over 200 at the Warp Gate. I'm happy right were it is. I didn't torture test it. Just gaming. Temps never went over 50 c. Should I go further or just stay where I am?

you should run prime or occt for stability/torture purposes, if its not stable you will get random bsod's and stuff, suggest you test it, as to how far you want to go that your personal preference

Sigh. You should never overclock with a stock cooler. They aren't designed to cool processors with higher clocks and higher v-core levels.

What you should do is stop and buy an aftermarket cooler. The most popular cooler is the CoolerMaster Hyper 212 or the 212 EVO edition. But there are other good brands.

+1 Agreed even though it's tempting because you have cool temps, you should not be overclocking on a stock cooler. I also recommend the Hyper 212 EVO as I have it on my 3570k clocked at 4.3GHz. My temps went from 70c at full load down to 50c at full load. Those coolers are amazing for the price!

My EVO just now came in the mail.

DeltaRecon2552 :

Did you read the Overclocking Guide by chance?

DeltaRecon2552 · Feb 5, 2014

Yes I did.

DeltaRecon2552 :

Fantastic. That makes life easy.

Now that you have a new cooler, run Prime95 with your current OC for a few hours to ensure stability. Temps with Prime95 will always be higher. If stable and want to go higher, increase clock and test again. If your PC crashes, raise v-core a little. Test again.

The EVO is a cooler for mild to high clocks, with suitable temps. It maybe difficult to get the 4670k above 4.5-4.6 on air.

Where can I download it without getting 10 million other add-ons and toolbars?

Yes it looks sketchy, but it's not. It's developer's website.

I'm also a fan of RealTemp temperature monitor.

DeltaRecon2552 · Feb 5, 2014

Okay. I'll download it real quick.

I got my cooler on and temps dropped a hard 20c on Prime95 with adaptive Vcore of 1.260 with .01 offset at 4.4 ghz.

EDIT: I hit max temp spike of 89c on Adaptive with Vcore of 1.280 so I set it to manual at 1.270. Testing now. Still stable at 4.4 ghz with stock CPU Cache settings.

barto · Feb 8, 2014

I like to do about 2-3 hours of Prime95 when testing. Remember, Prime95 will stress the CPU higher than any game so you'll see higher temps in Prime95.

DeltaRecon2552 · Feb 8, 2014

I know. I hit a max of about 60c in very stressful combat in PlanetSide 2. I'll run about 1 hour and try 1.260 vcore.

EDIT: 17 minutes into Prime95 I'm spiking to 85c.

barto · Feb 8, 2014

I think you should lower the V-core back to 1.21 or 1.22 and test. The basic purpose of raising the v-core is when you experiencing crashes. You don't need to raise it unless you experience the crashes. That is why you have such high temps right now.

DeltaRecon2552 · Feb 8, 2014

I'm stable thus far at 1.250. Go lower or let it test a while longer?

Again, I like to test 2-3 hours. OC'ing isn't a quick process. If you hurry it up, it will lead to you damaging parts.

DeltaRecon2552 · Feb 8, 2014

I've read the guide. I'm just trying to find the point that I crash right now. I'm running 1.240. If I don't crash within 20 minutes I'll go down 0.01. When I finally crash I will go up 0.005 and test, and if I crash again up 0.002 until I don't crash within 2 hours of Prime. I haven't crashed yet so I'm still going down on Vcore.

DeltaRecon2552 · Feb 8, 2014

That won't damage anything will it?

barto · Feb 8, 2014

No. You should be fine.

DeltaRecon2552 · Feb 8, 2014

I'm testing 4.6 at 1.240 vcore.

barto · Feb 8, 2014

Good to hear. Not to be mean, I held back responding just so you would test for a few hours.

DeltaRecon2552 · Feb 8, 2014

LOL. Well take all my work from the past few hours and chuck it out the window. I was only working one frigging core. I'm back at 1.250 at 4.4 ghz.

barto · Feb 8, 2014

Lol. Live and learn.

DeltaRecon2552 · Feb 8, 2014

I crashed again at 1.250 vcore and I'm now trying 1.260. I want to try to stay below 1.250 Vcore. Should I adjust my CPU Cache Ratio settings? Any tips at all to get my Vcore down?
