I can't get this thing stable over 4.2 ghz. I have been overclocking using the multiplier. I tried a core voltage as high as 1.250! and it still won't go over 4.2. Any ideas? It BSODS once I get to windows if its at 4.3ghz. Is there something I am overlooking? I am used to overclocking AMDs.

You may need more voltage. I need 1.3 volts in bios(1.28 volts in CPUZ) to get over 4.2ghz stable with my 2600k

Okay so I am at 4.3ghz and 1.32v. Maybe a stinker of a chip. Temps are only 65 under prime 95.

If 4.3ghz proves stable I'll go for 4.4. Is 1.4v the max for air cooled?


edit: it crashed after 5 mins of prime.

Using intel burn test, it says I am stable at 4.1ghz on standard setting. Voltage I set back to auto. Maybe I'll just leave it here. Temps got as high as 73 during burn test. Idle is around 30.

Edit: also this is a microcenter 3570k, the stepping is 9 and the revision is E1 if that helps.

Should I be disabling the turbo boost feature when I overclock?

I guess my 1.21V for 4,2ghz is lucky then? what temps under load do you got ? like prime 95

I would recommand not more then 1.34V for daily 24/7 gaming under Aircooling, your CPU will die even faster with more V

Mine will do 4.2 ghz at 1.21 volts but the second I put it over that it BSODS. I don't know how stable it is at 4.2, but it seems 100% stable at 4.1 so I may just keep it there since its running at 60* C and no higher running p95 with my case fans on low setting, which seems excellent to me.


I am getting idle 30 load in prime at 60. Burn test seems way more intensive.

I am using a CM V8 with the blue led Thermaltake A1926 @ 2000 rpm instead of the stock fan. This helped about 5 degrees C.

There are a lot of options for intel that I am not very knowledgeable like PLL.

What frustrates me is the guys that get 4.5 ghz with stock vcore and post all over the net about it, getting me all hyped up about this chip!!!! ;) Atleast my 939 clawhammer overclocked from 1.6ghz to 3.0ghz with the worst binned stepping so I guess I used my luck up on that one :p.

Sorry i was unclear with my words The temp question was directed @ BarbaricSoul


@amp281 Could you check With Cpu-z what Vcore is applied already on Auto settings and None OC. Maybe you just got a bad to OC Chip

It's better than mine does apparently, as I'll crash after several days at 4.2ghz*1.21volts. I need 1.25 in bios for 4.2ghz. Any farther, my voltage requirements start to rise pretty quick, as in 1.35 for 4.968ghz(48*103.5, highest stable OC I've gotten so far). But then again, my 2600k will only do a multi up to 48. Multi at 49 and it's instant crash.

My end is 47 @ 1,34V mine starts to eat V as well after 4,2ghz And running quite hot around 78-80C underload ...only got my H80 to cool it :<
I presume 4,2ghz is the magical gap between vcore=mhz increase

What do you mean? i set it to 1.21V in the bios as Manuel setting not offset. And Load-line calibration to very high my board is not drooping from 1.3661 to 1.21... it´s just Core temp reading it out wrong !

don´t be! we are just lucky to got a bit better chip...
Yeah and these things are so fast anyway it doesn't really matter besides online bragging rights :laugh:.

I've had 2 awesome overclockers (939 venice and 939 opteron), 1 average overclocker (phenom II 965be), and then this one. If I knew it was gonna be so limited I'd have not gotten the k edition :laugh:.

edit: My superpi 1m is 8.954s @ 4.1ghz. Still pretty damn fast.

So your CPU get whatever voltage you set in the BIOs? I've never heard of a motherboard that has absolutely no VDrop. Wikipedia has a pretty good explaination of what VDrop really is-
Voltage drop describes how the supplied energy of a voltage source is reduced as electric current moves through the passive elements (elements that do not supply voltage) of an electrical circuit. Voltage drops across internal resistances of the source, across conductors, across contacts, and across connectors are undesired; supplied energy is lost (dissipated).
Whenever electricity passes though wires and circuits, a little bit of the electricity is basically absorbed by the material the wires and circuits are made of, therefor your CPU doesn't get the exact amount of electricity your motherboard is set to send to it.

As for what coretemp reads, that's not what your CPU is using. That is what's known as your Voltage Range VID. From what I've read, Sandy Brdige CPUs have different VIDs. The individual CPU VID is set durning the factory testing of the CPU. Your 2600k is rated for up to 1.36 volts while mine is rated for up to 1.37 volts. Generally, the lower the VID, the better OC'ing results. The MAX VID for Sandy Bridge is between 1.38-1.39. Here's a pretty good forum post I found concerning Sandy Bridge VID-

Leave core voltage at auto,set PPL voltage to 1.65,leave multi at auto and put turbo clock for all cores at 44.

So your CPU get whatever voltage you set in the BIOs? I've never heard of a motherboard that has absolutely no VDrop. Wikipedia has a pretty good explaination of what VDrop really is-
That is not what i am trying to say. What i am trying to say is that my board Vdrop is around 0.010-0.015V even with High Load-line calibration settings.
1.225V in Bios results in 1.216V as you saw on the screenshot but it means that 4.2ghz is running with 1.215V Stable.

edit: Actually let me check in bios one sec.

Oh ok, I missunderstood you. That is pretty good VDrop you have. I'm actually set at 1.26 in MSI Control Center and showing 1.24 in CPUZ, so I have a .02 VDrop on my board.

Also, I was wrong with what my 750 board got. It had .038 vdrop, not .38 vdrop.

try running CPUZ and see what it says your running.
