I think he has the Micro one.

The latest for ASRock Z77 Extreme4-M is 1.20.

The latest for ASRock Z77 Extreme4 is 1.60.

Look on the box of your mobo and see if it says Extreme4 or Extreme4-M, as it will make a big difference.

ah ok I didn't even know there was an M version of this board.

I have the Asrock z77 pro 4, 4 pro for the last bios version is 1.20, not the M version

If you don't have fixed, then just use offset. I prefer it anyways! Saves power! thumb.gif

I have 50% = Level 3, offset -0.015 , in cpu z i vcore is 1.192 for OC 4.3, I can drop a bit but the offset to -0.020 or too little?

I can lower cpu pll voltage to 1.789?

Hey guys/kenny,

To start off, excellent guide. +rep

I actually have a few questions, as I am pretty new to this. I am using my sig rig.

I used your guide and it worked great. At the moment I am at 4.0 GHz @ 1.2V.The temps max at 71-78-76-72 during a Prime95 blend test for an hour. The Package temp is 79 if that means anything. I also ran IBT pm very high for 10 runs and the highest temps I got were 73-79-79-76 with a package temp of 85.

EDIT: I am now at 4.3 GHz @ 1.22V with a max temp of 74-85-84-77 on a high IBT for 10 runs.

I am not looking to absolutely max the OC capability of the chip, but do whatever is perfectly safe to do. What should my next step be? Should I increase the voltage or leave it? Should I change another value? These numbers don't seem to great, as I have seen many others getting 4.4 GHz with 1.2V and the same cooler.

I am also having some trouble with my RAM, which is in this thread:
http://www.overclock.net/t/1265910/samsung-2x4gb-asrock-z77-extreme4-help#post_17406158
That may or may not be part of the issue, if there is one. Screenshots of all of my settings may be found in that thread too (the CPU related ones might be moreso in the spoilers at the end

Last thing that I can think of now... What's the best way to test for stability? I will be gaming mostly if that makes a difference. I have IBT, Prime95, and AIDA64. If you could mention the program and all the settings that would be awesome!

Thanks in advance,
Big Al

If you like the speed your computer runs at then leave it. It's all up to you where you stop. Some chips just don't do as good as others. Remember that IB is about 5-10% better clock per clock than SB. As for the 80C temps, its all good. The chip will not be harmed until 105C at which it will shut itself off and prevent any damage from occurring.

I would use Prime95 Custom Blend 80% of installed memory (no other apps running). I didn't find IBT to be that great at stability and produced much higher temps than Prime95 (and no app to-date has even came close to Prime95 temps).

just had some question i have Asus baord and these settings are diffrent there

Turbo Boost Power Limit: Manual
Short: 500
Long: 500
Long Duration: 1

Again, only a limit. No limits for overclocking; set it to max.
Additional Turbo Voltage: Auto
Core Current Limit: 300


Max Watt i can put on short and long is 255?(should i just put 255?)

Also i dont have ocre current limit
But it says Short (core)current limit:
And Long(core) Current limit

Both need to be set at 1/8 of some Amperes? left it at Auto cause i really dont know what to set these to would like help with that:)

Started like you sugested with a 0.005 Offset And Level 2.

Resulted in 1.248 vcor in cpu-z with small drops to 1.244. (Not 100% sure if these are correct on last 2 digits but like 99% sure not at home right now:P)

and i could get to 45 multiplier.

MAx temps 1 hour blend prime95:

72-74-72-69.

Tried to get higher. but stopt at 0.030 offset(resulting in 1.272 vcore) and prime would crash withing 1-2 minutes.

Should i keep going or just settle with 45 multiplier.

My ram runs at 2133 MHZ at 11-11-11-30-2n(XMP profile).

Thnx!

Yep, just put it at max. I type in 3000 in all the fields and leave it at what it sets it too (in my case it was 500).
As for the Short/Long Current Limits: Set them to max too. Type in 3000 and then leave it to what it sets it too. They are merely limits used to amount of juice your system can use. It's like setting the max horsepower in a Viper to lower than what it can do... why would you ever do that?

Keep going! Max voltage is 1.52v and max temp is 105C. Any games you play won't come close to the Prime95 temperatures.

You can lower the CPU PLL as low as 1.5v. But most think 1.7v is the sweer spot. As for the offset, you gotta test that out yourself. See if it is stable, if not try another offset.
post #646 of 9460
in my experience cpu PLL from 1.832 (auto for my bios @ 4.4) to 1.586 (lowest allowed) made maybe a 1c temp difference but also caused instability. the best way to lower temps is to use a higher llc level I think.. it will take slightly more voltage w/ a higher llc like 2-3 steps, like llc level 3 as opposed to 2. but the temps will also be around 5c lower.

This is what I noticed as well.

Find the ratio you want, use the highest LLC load line you can, and find lowest offset possible to get stability.

For me it goes like this:

4.3 can use level 5
4.4 needs at least level 4
4.5 needs at least level 3

others are probably different though.

Hey guys,

Doing some OCing with my new 3570k and not sure whether to set the vcore to offset or fixed. I currently have it fixed at 1.22V.

If I should change it, what would I change it to? (I have never used offset).

Thanks in advance!

This is my sig rig if that helps.

I personally like Offset better...
