Overclocking Issues i5 4670K

Hey guys. It's me once again with a little bit of a problem  :P.

 

I'm having trouble overclocking my i5 4670k.

I've bought the cpu a couple month ago and at that time I was able to get a stable 4.4ghz (3.4ghz stock) out of it.

Which was great, cause it resulted in a pretty solid performance boost for both BF4 and Skyrim.

But then for a while I wasn't really gaming that much and to relieve some pressure from the CPU I undid the overclock

for the time being. But now I tried to get the 4.4ghz back, cause I'm currently doing some more gaming again and some

content creation. But even on 4ghz my System will eventually freeze during AIDA stability testing.

And I haven't changed and specs of the system.

 

Specs:

  • Mainboard: Gigabyte Z87X-D3H
  • CPU: Intel Core i5 4670K
  • Ram: 8gb 1333mhz Teamgroup (2x 4gb dim)
  • Graphics: R9 280X
  • Power: Cooler Master 650W Modular

I have ruled out temp problems, I was monitoring my CPU temps very closely during stress testing and CPU temps didn't rise above 70°C (158° fahrenheit).

I'm using a Noctua NH-D14 CPU Cooler and all Noctua NF-F12 fans in my Case: Picture

 

I've tried a 4.4ghz overclock with 1.3V. But couldn't get it running.

 

I was wondering if perhaps my powersupply or my ram could limited the overclock. The power supply and the ram is from a former system of mine and they are both 4+ years old.

And I definately changed the connections of my power supply since I last overclocked. Could it be a problem, that the cpu doesn't get enough amperage?

RAM is not the issue, might be your PSU that has degraded to a point where the rails are not stable enough.

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

@Yakshirak check other BIOS settings. You can also disconnect and reconnect the 8 pin CPU power, though I doubt that this will help in any way...

 

I'm not an expert on this... so some resident overclocker will be a better person to listen to...

 

Also, your profile pic creeps me out...

I've just checked the Gigabyte website for any recent bios updates. And they release a new version in late August this year. 

I'm running on the new bio right now on 4.4ghz and 1.3V with intel turbo boost disabled. And so far it looks stable.. (aida for 25min now... it crashed after like 2min running aida before the bios flash)

I will report back with more results.

Can anyone tell me if this is normal: Picture

 

The ram frenquenzy seems to be a bit on the low side? Or is this normal?

your ram is dual data rate so you are currently running your ram at 1333mhz

if you have faster RAM you have to enable XMP profile 1 in the BIOS for it to work at the rated speeds.

Also you should dial in the proper voltage for the sticks manualy.

Ok. I've managed to get a 4.2ghz running with 1.25V on the CPU. I've been running Aida64 for about 19h now and had no crash.

 

All I really did was flash my bios and fiddle around a little bit more than usual with the voltage. But I'm pretty satisfied. It's not what I had, but I blame the deterioration of my power supply and or CPU.

 

I will be upgrading my build soon with 2133mhz 8gb Ram and a Corsair RM750 PSU. And then early 2015 I will probable go for 1 or 2 GTX 970s.

 

Thanks for the help guys! I really appreciate this community :)

Just a quick question. What is your voltage in CPU-Z vs. voltage in your bios. I just got a new power supply myself. I was 1.26v in bios on my old power supply which was 1.272v in CPU-Z. I have 1.29v in my bios with the new PSU for a 1.272v with my new PSU. You may also want to bump your memory voltage to 1.55v up from 1.5v. If you have 1.6v memory a slight bump up may help with stability. You should be able to get 4.5ghz out of your 4670k. I have the 3570k and anything above 4.5ghz takes a big increase in voltage. They use the same process on Haswell so the overclocks are quite linear with ivy bridge to Haswell and the Devil's Canyon chips. The Broadwell stuff is all new with DDR4 with 14nm.

I have the voltage in the bios set to 1.3V and cpu-z displays 1.299V. So I guess it's fine.

And I don't really know why, but for some reason, when overclocking I can't get stable above 4.2ghz. Do I need to ramp up the voltage even further? Because heat output isn't a problem at all. Under load with 1.3V my CPU hover around 70°C... so there's that.

i did not see you mention your uncore (cache).

You should manually set uncore to 3.5 @ 1.150v until the core is stable. Heck there is not much to gain oc uncore anyway but at least do that after you are happy with core.

Also set your input voltage to 1.850v.

Ok. I've got a stable 10 minutes out of my 4,5ghz @1.35V run before I ended the test and tried ramping the clockspeed up to 4.6ghz. But even @ 1,4V 4,6ghz just doesn't get stable.

I am running a longer stability test right now with these settings @4,5ghz: Picture

I will edit this post with my results. Again thanks for all the input fellas! I really appreciate it.
