i5-4670k overclocking

post #1 of 8
Thread Starter 
hi guys,

I recently bought an intel i5-4670k with a msi z87-g45 mobo with a corsair h110.

I have tried to overclock and stress test but in need of help.

First off, I have tried to pull my cpu frequeny to 4.0Ghz with auto voltage.



When I stress test this I get to a voltage point of 1.39V maximum at full load.

The temperature doesn't seem to dangerous but from what I read, that is a very high voltage.

Also, I tried stress testing it at 3.4GHz with cpu voltage as auto but voltage still strikes up to around 1.26V.

So I have two questions:

1. Is it OK to use "auto" for cpu voltage?

2. is my CPU faulty at all? Because it requires a high voltage to keep it stable at 3.4GHz.

Thanks

Also, when I monitor my Vcore, it sometimes suddenly spikes up to 2.04V for a very very short time. Nothing happens, but is this normal?

Read the guide in my siggy first.

Check uncore mult, it should be manually set to stock.

Forget autooverclock. Overclock it yourself. x264 to stress. Monitor vcore via Hwinfo.

It is NOT OK if it goes up to 1.39 on AUTO.
Set it to 1.2..or use the offset.
Offset will raise it AUTO as well..but I'm pretty certain it'll be controlled by the chip.
You shouldn't need any more than 1.2 for 4.0 and a little more..

Bro, are you on adaptive voltage while stressing with a synthetic?

No, that's exactly what you don't do if you're running a synthetic stress test like Prime or Ibt or Linpack.

 

Get it off auto-overclock. It's weird auto-oc is tripping out like that but until you actually try to overclock with any sort of seriousness, we can't establish if your CPU is good or bad.

So do I just leave it at auto if im running a prime95 stress test?

Set it to manual.

 

Like I said, ditch auto-overclocking. You need to input the voltage for a multiplier yourself to get any real results.
