post #271 of 19539
I've OC'd my 4670k to 4.5GHz stable at 1.25v. Max Prime95 temp is 70c. Uncore/ring bus is at stock 3.4GHz. Is it ok to leave it at 3.4GHz for 4.5GHz or even if I attempt higher CPU OC?

yes got my 4770k @ 4.6 with uncore at 3.5 you can always try incrasing in 1's to see if it can run at 4.5

Hi,

So I'm trying tofind stable voltage for 4.7 Ghz for my 4770k. I ran AIDA64 for stable test in 12 minute, than I had BSOD. I had 1.220V in BIOS. manual.. CPU-U shows 1.218V. You can see it here.. sorry for bad angle. It is snapshot from my Camcorder.

BTW: I set cachce on 35 ratio. What about voltage? I leave it on Auto, Do you recommend something about cache ratio? thanks to all

Yes, leave at stock, go for higher overclock., Once you stop then try to raise uncore.

 

 

The most important thing is how good your CPU is. If it requires low voltage, you don't need a fancy watercooling system or mobo. I saw a guy with Evo 212 at my frequency because they needed so little volts.

what about this:

if I have a good or decent cpu and a ok motherboard, will it be overclocked better w/ H80 cooler?

Motherboard matters very little. Your overclock will be controlled by the CPU, not the motherboard, unless you are using some kind of exotic cooling.

1.22V is very low for 4.7, you will most likely need to raise the Vcore to get stable at that speed. If you crashed at 12 min in Aida, then you aren't really very close to stable. And I'd set cache ration to 36x, just to take that variable out of the equation while you are working the overclock (35x sometimes auto increases higher on some boards).

As long as ring bus is not overclocked much, it can go on auto. I've added that info to the guide.

Each selection (Blend, Large FFTs, and Small FFTs) has a small description of what it tests and is better at testing various different components of you system and overclock. As long as you are in the low 90s you will be ok temps wise for short tests. For longer tests either try to get the temps down (better cooler, lower ambient temps, or even lower the voltage and multi) or use another stress test (OCCT is a good alternative, although you will experience similar temps). Let us know how you make out...

Thanks for the info. I'll try it again tonight. My cooler is a H100i btw.

I try to overclock with 44 with everything auto .

Prime95 for at least 20 minutes:

100-97-95-87

it seems that core 0 is always high then all 3 cores. why is that?

what do I did wrong to make core 0 so high?

Bro, core 1 being the hottest is fine. First of all, the biggest determinant of your temperatures will be your voltage. Core 1 tends to get the hottest for mine and other people's too. More interesting is that your fourth core is 87 degrees, 13C cooler than your hottest core. I think that's still small enough to be ok though considering you're hitting high temps.

 

Also, be careful. I personally wouldn't want to hit 95C+.

Auto voltage at 4.4 might be crazy high. Did you check to see what it was? You are probably better off using a manual voltage.
