Yep!

It will be 4.5 GHz because the settings I am recommending include setting the multiplier to 45.  So, go ahead and do that.  It'll be alright.

This will be something you can determine without anyone else's judgment by seeing whether or not your system can run Prime95's Custom Blend test for 14 hours or slightly more.  14 hours is how long it takes Prime95's Blend test to go through all 84 of its FFTs one time each (it may take a little longer than 14 hours, but it won't be more than 15 hours).

 

The reason for doing the Custom Blend test is so that you can tell Prime95 to use about 90 to 95% of your memory instead of the 1600 MB of the default Blend test.  To do the Custom Blend test, just select Blend and then select Custom.

 

However, the first thing to do is just post what full-load (Prime95 Blend) core voltage you get with these settings.

[*] Ai Tweaker: By All Cores (Can Adjust in OS) (this is the multiplier, which will be set to 45 for now)
[*] Ai Tweaker: CPU Offset Voltage"

 

I'm saying that these are the only two settings that you will still need to come back to once in a while in order to keep tweaking the overclock (for example:  to raise the clock speed or the core voltage).

Enable Internal PLL Overvoltage.  So if it boots, then leave it disabled.

 

If that doesn't work, then put it back to Disabled and increase the Offset Voltage until it boots.

 

If the motherboard won't boot (if it doesn't even get a chance to begin loading Windows), then we'll go from there, but this is a very unlikely event to occur with these settings.

Absolutely!  This is actually why I'm recommending that we start at 4.5 GHz.  I see no reason to start lower than that.  ;)

I don't know what these people are saying, but I know one thing is for certain:  if it's stable, then it's stable and you can use your computer however you want with peace of mind.

Cheers for spending some extra time on my case.
I think 4.5GHz should be enough of OC for the Nvidia 600 series cards? And also for the normal performance.
If the temps are okay, should i push to 4.7GHz? (We'll talk about that later, will probably pm you by wednesday morning) rather than posting here if you don't mind. So check your Inbox!
Thanks again.

`

when i pair my 2x4 with that extra 4 i can boot into OS but when i try to OC it just require restart after some time...
or its doing on its own...
now what im thinking that those sticks have to be on 16gb to work ok cause one slot is left opened

Question about the Asus AI Suite. I want to set different oc settings in Windows with the Turbo V, but it seems like I can't adjust the multiplier with it. I clicked ON and let it restart my comp, but after that it's still the same. Does anyone know what I need to set in Bios or AI Suite to allow it to change the CPU multiplier in Windows? Thanks.

Have CPU-Z open while something like Prime95's Blend test is running.

I think so, but this is always the judgment call of the end-user.  ;)

Thanks again.

 

I'd prefer that you post a message in this thread instead of sending me a private message because that way we may be able to benefit other members.

 

Anyway, I'd love to try 4.7 GHz, but for now let's wait and see what these settings for 4.5 GHz give us.  :)

I'm not sure about this, but I think this needs the Intel Management Interface to be installed.  Edit:  I just tried it, and it turns out that I'm wrong.  Mine doesn't save the settings either.

 

Why not do this directly in the UEFI BIOS instead?

I want to try set a higher oc setting that are only used for running emulator, for daily use 4.6ghz is more than enough, but I want to see if I can push 4.7-4.8ghz stable and use that setting only for emulators. If anyone knows how to enable that setting in Turbo V, please share. Thanks.

I can't explain any better than wikipedia. I did try playing 4K video on a first gen Intel Core processor & ATI 5870. With software acceleration it can play fine but when using hardware acceleration, the whole computer crashed. That is only one instance of 4K video.

Hmmm, can you direct me to a link for a 4K resolution video?

An example of a 4K resolution video:

Click the cog wheel, and select "Original".  This will result in the 4K resolution as opposed to a lower res like 1080p.  When you're watching, pay attention to the details.

From what I've read, clock-for-clock, a 3570K is noticeably a little faster and more powerful than a 2500K, but when a person is only concerned about the clock speed number, a 3570K would be disappointing because it tops out on air at around 4.5 GHz to 4.6 GHz.  However, again, clock-for-clock, the 3570K is a little faster.  So a 3570K at 4.4 or 4.5 GHz is like a 2500K at 4.7 or 4.8 GHz.  Going further, clock-for-clock and voltage-for-voltage, Ivy Bridge's temps are higher than Sandy Bridge's.  So the temps for Ivy Bridge at 4.4 or 4.5 GHz with whatever the voltage would be for that are higher than the temps for Sandy Bridge at 4.4 or 4.5 GHz with whatever voltage would be for that.  However, again, and one last time:  clock-for-clock, Ivy Bridge is a little faster.

So, Ivy Bridge overclocking is a little different.  Some will contend that it's not different but a little inferior because the potential maximum overclock is lower, but these CPUs are still a little faster and more powerful than Sandy Bridge.  So when I say that Ivy Bridge overclocking is different, I mean that the approach is different when one knows what to expect.

In other words, I think the expectation is to top out at about 4.5 to 4.6 GHz on air just like how Sandy Bridge tops out at around 4.7 to 4.8 GHz on air.  Yes, some air coolers can allow Sandy Bridge to reach 5 GHz, but that isn't the average.


I can help you overclock.  You are right that it's really easy, and I think I might be able to make it even easier.

Let's try these settings in the UEFI BIOS and go from there:

[*] Ai Tweaker:  Ai Overclock Tuner:  Manual
[*] Ai Tweaker:  BCLK/PCIE Frequency:  100.0
[*] Ai Tweaker:  Turbo Ratio:  By All Cores
[*] Ai Tweaker:  By All Cores (Can Adjust in OS): 45 (this will be 4.5 GHz because 45 x 100.0 is 4500)
[*] Ai Tweaker:  Internal PLL Overvoltage:  Disabled  (Note: enable this if Windows refuses to boot with these settings here)
[*] Ai Tweaker:  Memory Frequency:  set this to whatever memory speed your memory is supposed to be at stock
[*] Ai Tweaker:  iGPU Max. Frequency:  Auto
[*] Ai Tweaker:  EPU Power Saving Mode:  Disabled
[*] Ai Tweaker\  CPU Power Management>:  CPU Ratio:  Auto
[*] Ai Tweaker\  CPU Power Management>:  Enhanced Intel SpeedStep Technology:  Enabled
[*] Ai Tweaker\  CPU Power Management>:  Turbo Mode:  Enabled
[*] Ai Tweaker\  CPU Power Management>:  all of the rest:  Auto
[*] Ai Tweaker:  Load-Line Calibration:  Ultra High (this should minimize vDroop to its least amount)
[*] Ai Tweaker:  VRM Frequency:  Auto
[*] Ai Tweaker:  VRM Spread Spectrum: (this disappears when setting "Phase Control" to Extreme, and we will do that next)
[*] Ai Tweaker:  Phase Control:  Extreme
[*] Ai Tweaker:  Duty Control:  Extreme
[*] Ai Tweaker:  CPU Current Control Capability:  100%
[*] Ai Tweaker:  iGPU Load-Line Calibration:  Auto
[*] Ai Tweaker:  iGPU Current Capability:  100%
[*] Ai Tweaker:  CPU Voltage:  Offset Mode
[*] Ai Tweaker:  Offset Mode Sign:  +
[*] Ai Tweaker:  CPU Offset Voltage:  0.005
[*] Ai Tweaker:  Everything else:  Auto, except for CPU Spread Spectrum.  CPU Spread Spectrum should be disabled for Z68 boards because having it enabled results in actual the BCLK being 99 MHz



[*] Advanced\ CPU Configuration>:  CPU Ratio:  Auto
[*] Advanced\ CPU Configuration>:  Intel Adaptive Thermal Monitor:  Enabled
[*] Advanced\ CPU Configuration>:  Active Processor Cores:  All
[*] Advanced\ CPU Configuration>:  Limit CPUID Maximum:  Disabled
[*] Advanced\ CPU Configuration>:  Execute Disable Bit:  Enabled
[*] Advanced\ CPU Configuration>:  Intel Virtualization Technology:  Disabled
[*] Advanced\ CPU Configuration>:  Enhanced Intel SpeedStep Technology:  Enabled
[*] Advanced\ CPU Configuration>:  Turbo Mode:  Enabled
[*] Advanced\ CPU Configuration>:  CPU C1E:  Enabled
[*] Advanced\ CPU Configuration>:  CPU C3 Report:  Disabled
[*] Advanced\ CPU Configuration>:  CPU C6 Report:  Disabled



Now, once all of these are set, there will only be two settings that we will need to tweak going forward (and so this is where it becomes easy):

[*] Ai Tweaker:  By All Cores (Can Adjust in OS) (this is the multiplier, which will be set to 45 for now)
[*] Ai Tweaker:  CPU Offset Voltage



So really, overclocking Sandy Bridge mostly becomes a matter of adjusting only the multiplier and the voltage.  smile.gif (I don't know yet if this applies to Ivy Bridge too)  Unfortunately, it can only become this easy once you know what to do with all of these other settings!  hehe

If these settings allow you to boot into Windows, then can you report back what your full-load voltage is as displayed by CPU-Z?  For full load, I recommend running Prime95's Blend test for a few seconds.

Thanks, benceh!

Have a concern with some settings. I reckon that last year you were recommending to start off with Manual voltage first and when you get the desired voltage already, then that's the time we go with Offset?
