Here is intels demo for turbo:

Oh so the option to further increase the speedstep multi is board exclusive?

I have a i5-2500k with a P8P67, speedstep and OCd using offset. The first one is on idle/normal PC usage, the second is under load/gaming.

I'm sure other overclocking boards can do it too, not sure since I have never owned anything else besides the P8P67

Every P67 board has speedstep and allows you set it up to your liking. It's an Intel feature, not board dependent.

Well, at least i (to this day) haven't heard of one that lacks the feature.

On my P67A UD4 B3 if you set voltage to auto or normal then it will still drop to around 1v at idle along with the lower 1.6ghz cpu speed.

Wow, so many new people insisting he did something wrong to start the thread off...

Disable C1E, Speedstep, and any other BIOS options that change your clock speeds or voltages dependent on outside factors.

If you have a doubt about a setting, better to ask first and not make a mistake.

Good luck.

Thanks guys.. will ask around again once I receive my board and cpu.

I just want a rock stable 4.2 Ghz with an H50 cooler. And hoping that it can still clock down and volt down normally.

I did rep accordingly

Guys!

Finally got the board and CPU

Can someone please lend a hand on how to get a 4.2 Stable OC?

I have the ff:

2500k
ASUS Z68 V PRO
G.Skill Sniper 1866 (running at 1600 only.. idk how to chang it)

....

All I know is that I should change the CPU multiplier first.

I also want a it to downclock like the other guys do it.. so I can save some lifespan and electricity.

Would appreciate someone holding my hand xD This'll be the first SB OC I'll do

Before you do any kind of overclock it would be a good idea to note down what your stock voltage is. Then it is just a case of tweaking voltages in accordance to the multi used for your desired overclock. I would definitely look at the 'sandy stable club' for overclocking reference, it has a detailed spreadsheet that I compiled to show voltage against overclocks and temps against voltages.

Hope that helps.

How do I know what my real stock voltages are?

With CPUZ atm: It sayss

Core Voltage 0.984 to ~ 0.98X (keeps changing)
Core Speed ~1605.5 Mhz
Multi x 16.0
Bus Speed 100.3

I just want a "mild" 4.2 Ghz that can downclock itself when idle. I know this is lame but.. can't the mobo adjust stuff for me automatically if I hit it to a x42 Multiplier? Then adjust from there?

Thanks for the quick response tho.
